2009 Yamaha YZ250 2-Stroke Bike Test

Because We Can...

2009 Yamaha YZ250
Professionally, the YZ250 (12) has to compete against the likes of Yamaha's YZ450F (7) and the rest of the 450 monsters. Now, with rule changes by the AMA, amateurs can race the 2-stroke in the 250F class which is much more realistic.

Our quartet’s throaty rumble and whir of cam chains was constantly interrupted by the zingy sound of an expansion chamber and shorty muffler. The AMA now allows 250 2-strokes to run in the 250F division, which has opened a whole new avenue for non-professionals. Since Yamaha is the only Japanese manufacturer still producing and importing its 2-stroke line, we brought out the YZ250 to run alongside our quarter-liter Thumpers, just to see if it belongs in the mix.

Weighing the same as our KX250F, the 231-pound machine has a distinct advantage in terms of sheer horsepower. The YZ put out 41 ponies on the Mickey Cohen Motorsports dyno while the most powerful F model spun up 34 (Honda) – only 83 percent! However, the way that power is distributed across the rev range is where the differences lie.

Basically, it is all a matter of personal choice. The 2-stroke is definitely a faster machine, but it takes more skill to get the most out of it, and some riders preferred the even spread of power from the 4-stroke, despite having less available. The one thing our testers did agree on was that the YZ can be very fun to ride, especially in the right circumstances. Here’s how they describe it.

2009 Yamaha YZ250
Our novice was one of the riders who favors the 4-stroke. The YZ was just too unpredictable for him and the confidence and precise control allowed by the 250F is ultimately a better fit.

JC Hilderbrand – Novice
Man, that YZ really surprised me. I haven’t ridden a 250 2-stroke in a long time, or at least one that is mechanically sound. I thought for sure that it would be a lot more fun because that’s what you always hear about them, but honestly it wasn’t as much fun as the 250F machines. The YZ basically just wears me out. It’s definitely way faster and as soon as you snap the throttle it wants to go, but you really have to be more careful about your gear selection. I kept missing corners because I’m not used to the lack of engine braking, so I had a hard time evaluating how well it turns. Since I spend so much time worrying about the track obstacles, especially jumps, a 4-stroke’s smooth delivery is ideal. There’s nothing worse for me than trying to size up a new jump and worrying about hitting the powerband right on the face of it. I love that it’s cheap and I’m sure if I forced myself to spend more time on it I would start to think otherwise, but I really have no desire to.
Sherri Cruse – WMA Pro

By far the best bike of the test ride. Although it wasn’t actually included in the test, it was fun getting the chance to ride the 2-stroke again. It sounds like they’re letting the 250's ride in the (amateur) 250F class, and personally I think it’s a great idea! If the women get a chance to ride them in WMA I will definitely get my hands on one. I know I would ride one at Southwick, but some of the other tracks I would go back to the 4-stroke. I would jump around a little bit.

"I just shake my head and look at my new EFI bike and want to kick it. "

Alvin Zalamea – Vet Expert

2009 Yamaha YZ250
The bike is definitely capable of winning against 250F equipment in the right hands, but really this machine is the most rewarding if you would rather bring home smiles than trophies.

I should’ve bought a brand new ‘09 Yamaha 250 2-stroke. Instead I bought a new CRF450R for $8300 out the door and put 1000 bucks in suspension from Enzo. That’s stupid! Street bikes sell for less. I’m seriously thinking of selling it and buying a YZ250. I’ve just gotten so lazy on the 4-strokes that I’m starting to forget how to ride. I just recently rode with Greg Albertyn at Milestone and he’s riding a 2004 RM250 and he’s spanking all those new-school, bubba-scrubbing pro kids on 250Fs and 450s. Literally, people pull off the track and ask who that Number 7 guy is on a 2-stroke. I just shake my head and look at my new EFI bike and want to kick it. I thought it was the bike and new technology and all that crap, but it’s not the bike, it’s the rider. This is all a conspiracy to keep spending more money to have the best stuff. Well it’s working… So if you’re on a budget, do yourself a favor and buy a brand new 250 2-stroke. Guaranteed you’ll have more fun and go just as fast, if not faster, than your buddy at the track for half the price! If I were competing in the amateur Lites class it would be a no-brainer to choose the 250 2-stroke.

Colton Haaker – Expert
The 2-stroke was a nice transition from the four-bangers. The power is a torquey even feel. I am very used to a KTM 250 and the Yamaha was easy to ride and immediately comfortable. I wouldn't call it a track bike, it is not comparable to the two-fitty Fs. I could take that bike off-road though and make it extremely competitive in EnduroCross. Some different gearing, maybe a flywheel and it’s good to go. The fact of the matter is 4-strokes are still better.

2009 Yamaha YZ250
Tod - "I own a YZ250
- and love it!"

Tod Sciacqua – Vet Pro
The ‘09 YZ250 is an all-around great package I raced the whole EnduroCross series and thought I was on the best bike out there for me. There has been little changed on the newer 2-strokes in the last few years. Most of the attention from the manufacturers has been on the 4-strokes. If I were to have the choice to race the 2-stroke 250 or the 4-stroke, I would pick the 2-stroke hands down. It has amazing, usable power and lightweight feel. With the price of 2-strokes and the maintenance cost, why not have a YZ250 in the garage.

For My Money.
Full scorecard.

Ren Schmidt -Pres. of Revanche2strokes.com  December 14, 2010 06:16 PM
It's frustrating, this which is better, 2 stroke or 4 stroke? No matter which bike you prefer, everyone must admit one thing. We ALL should be allowed to choose whichever one we want based on fair tests and fair competition. This is the frustrating part. NEVER do we get fair tests and or fair competition, 250's should race 250's...period. When the competitions are fair, then the decisions should be made, we automatically "pit" the smaller 2 stroke with the much bigger 4 stroke, and we go away saying things like... the 4 stroke has more power and torque, etc. These tests are not fair and the reader rarely gets a fair comparison to judge. This is because the spineless AMA and the big 4 want us puttting the 2 stroke at a disadvantage.... and we do! If the 4 stroke is better, let it be better because it competes fairly and wins, not because it gets to race a machine that is at a huge disadvantage. If I was a 4 stroke guy, I'd want to beat the 2 stroke in nothing but fair competitions. Wouldn't you?
2strokes are awesome -I used to not like 2 strokes untill i got on one  November 2, 2010 07:39 AM
Im 14 And i have a yamaha yz250 2stroke and its and awesome bike i love riding it it does all the things i want it to do with no problem. You can be at a dead stand still and have a car going 60 and as soon as the car gets with in a car length away ill floor it and it will keep up with car and bette it. It has awesome power & if you put the right parts on it you can get the top speed up too 111mph but stock it goes around 80 to 85
baz 78 -2 stroke till i die!!!!  October 20, 2010 02:14 PM
i own a yz 250cc 2 stroke and love it i have rode some 250 four strokes and find they are a lot easier to ride with there smooth power but if u can ride a 2 stroke properly then a 4 stroke wont look at you!!! i think its a shame now when u go to a race and only see a handfull of 2 strokes there they sound amazzing the smell of 2 stroke in the air is great..i think if people who ride 4 strokes just now were to jump onto a 2 stroke there lap times would suck as it takes more skill to ride a 2 stroke..4 strokes are far more forgiving personally i love the challenge and wont be changing like everyone else seems to be doing...LONG LIVE THE 2 STROKE!!!!:)))))
gotdirt? -2stroke vs 4stroke  September 1, 2010 09:54 PM
ok i read some of this comments and here my 2 cents..i own a 06 yz450f and a 96 yz250 two stroke and is like day and night difference. 2 stroke is pure adrenaline raw power dont care if i crash or if engine blows out cuz is a cheap bike pay 1400 buck used..lol.now my 4 stroke got it for 4500 used is my baby my ferrary i will die if i crash my bike or scratch it plus im scared to blow the engine so i dont ride as much ..lol i like both bikes just about the same power little more fun the 2 stroke to play around the 4stroke smooth power but still lots of power any way if you got money get the 450 if you broke get the 250 two stroke..simple cuz both 2 and 4 are lots of fun..
KS -YZ 2 Stroke  August 4, 2010 12:30 AM
Well, just bought an YZ 250 2 Stroke for Offroadriding.... Modified a little bit to make it a little bit "unaggressive". More Flywheel,bigger Tank,FMF Muffler, and finish is the best Bike for Offroadtrail ever.. The only Bike which I really was satisfied like my YZ now was an 98 Gas Gas EC 250 with hydraulic Clutch,but for the Yam I can get cheaper parts and I hope 2Strokes never die!!!
DoubleDD'sRaceTeam -2-Stroke  July 31, 2010 12:00 PM
CR250 CR125 CR85 All Me and my friends have ever ridden is 2Strokes.
Case in point Listen well
If the Four Strokes are so awesome Why does it take Twice as many CC's
to do the same as a 2Stroke. Less is better. A Scam the company's put out to make more Money. They sell a 2Stroke and make almost zill after the sale because of how well they're designed. 4Stroke you pay forever like a HomeLoan. Just trying to help. Think about it???
Doug Williams -Please Yamaha keep making the yz 250.  July 28, 2010 06:08 PM
Get the YZ two stroke, throw on a gnarly pipe, a desert tank and a weighted flywheel and you've got yourself one hell of a trail bike. This July I did 81 miles of trils to celebrate my 44th birthday. All in less then three hours. Riding a two stroke is like an art. Let the bike become part of you. Ride it, don't let it ride you.
Bob -2006 YZ 250  July 24, 2010 11:58 AM
There is nothing worse than waiting 15 minutes for your buddy to get his F started after a bail out. I'll probably never make the switch to the big 4 strokes and I hope KTM and Yamaha stay true to the sport by standing by the 2 strokes. Several of my friends have switched over to the 450's and yes they out run the 2 banger down the straights, but through the woods they struggle to keep up and on tight technical hill climbs or in the mud they get all out of shape. Maybe if you are set on racing motocross and can afford the high cost of owning a new 4 stroke it's worth it, but I don't see the need if you mainly ride woods and keep your bike for more than a year or two. Plus, it seems like the younger generation is missing out on developing the fundamental skills that a two stroke forces you to learn. Just my two cents.
F.M. -heres my 2 cents  June 2, 2010 07:47 PM
Honestly, I don't find that either is vastly superior over the other. Honestly, for a nooby a 4t is gonna be easier to learn on because the low end is usually more substantial, and the power is overall smoother. A 2 stroke on the other hand, has the advantage of having tons and tons of power. To sum it up, i guess 4t's are easier to ride fast, but a 2t is gonna be way faster in the right hands.
Mista YZ -Thumpers are unrealistic  May 21, 2010 08:26 PM
I can't believe that almost everybody nowadays are saying thumpers are SOOOO much better than smokers. C'MON!!!, they're faster, lighter, technologically advanced, u can work on it with a butter knife, they retail for 1000$ less, and when u need to get it new parts, u only need 200$ to do it, while a thumper costs an arm and a leg to do the same thing. And they're much more refined machine as a whole. Do u need more reasons to buy one?
Brian anderson -2005 yz144  May 13, 2010 08:15 PM
they all ways tell me get a 450 you will be faster and i tell them no thinks ill just be broker not faster i think there scared of me getting allot faster on my 144 and start waxing there 450's and showing them up and in the corners i all ready am (now we are talking a bunch of older weekend riders not pro's} my 144 is fantastic and you know what els it is nimble and just so damn much fun to ride i will never buy a used 4stroke but ill buy a used 2stroke any day of the week knowing that i can get it in great riding condition for just a few coins compared to the 4stroke LONG LIVE THE 2STROKE
Mark Koven -Future of the sport  March 30, 2010 06:10 PM
I would like to see the 2 strokes remain.... the four strokes are raising the cost of racing to unreal levels. I see lots of the new f's for sale used and am hearing nightmare stories about engine rebuilding costs.
bigboost -stroke me  March 4, 2010 08:23 AM
i had a ride of a new fuel injected crf450 the other day and dont get me wrong they do go hard but i get more of an addrenalene hit riding my 1996 yz250 2 stroke, not only that my yz is so much lighter and a lot less to maintain then a 4 stroke would be od rather put a piston and set of rings in my bike then rebuild a 4 stroke more crap = more money ie valves,cam chains,injection or wateva.

dont get me wrong 4 strokes are easy to ride and smooth power but thats about it. my 96 zy250 eats 2005 cr250f hands down and keeps up with most new 450f! do yourself a favour buy a 2 smoker
TwoStroke4Life -Can't compete  December 29, 2009 07:33 PM
Can't beat a two stroke CC to CC with a 4-Stroke, simple and plain. This whole four stroke thing is just a money making deal. Look how much money a brand new 450F is? Look how much money you'll have to spend on the engine alone to be competitive in racing? Look how much money you have to spen to overhaul one a fourstroke? And now with this new EFI, unless you're a mechanic with all the correct tools, forget about it! Two strokes are the way to go. Ready out of the box, you can just about overhaul it with a wrench and screwdriver (Not to mention it costs about half to rebuild the top end compared to it's 4stroke brother) and they're a blast to ride.
Duane -two strokes  December 27, 2009 07:53 AM
i love two strokes!!!! keep on making them yamaha and ktm!
duane -two strokes vs 4 strokes  December 27, 2009 07:51 AM
four strokes smoke also you just cant see it all the time. two strokes smoke when cold but hardly ever when warm, if you got your oil right!
250Beg -09 yz250  December 24, 2009 05:59 PM
Bought a new 250 2t a couple weeks ago and absolutly love it! Traded my 06 crf250r in on a 09 yz250 and couldn't be happier. Bike starts easy, weighs just the same, and tooooons more fun!!!! 4t had a slow building power and the 2t has the snappy, instant throttle response. Not to mention more power. 4t is more granny/old man frienly due to the slow building power. Ride mostly woods and always had issues with the 4t overheating in single track trails, and if I stopped to wait for the other guys to catch up I would have to cut the bike off until they got there, then restart it because it would overheat real easy if I was sitting still. Havent tried it out on the track yet due to all the rain were getting here. Takes a little getting use too since ive owned 4t for so long, havent rode a smoker since i was a kid but absolutly love it. I would definantly recomend a yz250 to anybody wantin a new bike. IF your lookin to buy a new bike make sure u take a look @ a yz250 and dont forget about how easy and cheap it it to rebuild a 2t. Ive owned both and love my smoker!!!!! :)
clemintime the original -lol  December 7, 2009 10:57 AM
its a bad thing :(

richard -05 yz 250 2 stroke!!!!!!!!!!!!!!!!  December 1, 2009 12:05 PM
i have an 05 yz 250 and i have beat the hell out of all kinds of 450's yamaha honda kawasaki four strokes suck on a track off road hillclimbs all around the 2 strokes are the way to go motorcycle companys need to quit making fourstrokes and just make 2 strokes and the world would be a better place mabey a little more smoke but a better place and alot more fun
piston heads -lol  November 16, 2009 10:36 AM
hello im back for great new convorsation ive just brought a cer 500 af and wat bike
MT smoker.... -Thank Goodness for YAMAHA  November 9, 2009 03:27 PM
Can't wait to get my 2010 YZ250... Yes without the F, I have owned only 2-strokes and will never change my thinking. Some of you have became soft and dont want to work hard to go FAST... Well I am 38 now and I'd like to feel some sack between my legs and feel the rush, then to whine cause you got smoked by a 2-stroke...
DT -Ricky-cr500  October 5, 2009 07:58 PM
It is a simple answer to your question to why not make a 500 smoker.They can not put any 450 four stroke they will get close to it!They are still trying to figure out to race a 250 two stroke in the same class.
Hawkins -2-Strokes  October 4, 2009 09:37 PM
im getting a KX250 2 stroke 2004. from all the talk i hear 2 strokes are going to be very good. its my actual bike but i've been riding my friends bike for 1 year which is a rmz250 really dont like how heavy it is. so im looking foward to the power to weight ratio in the 2 strokes, can wait to get it.(this weeked is the truth about 2 strokes for me)
DT -4stroke What!!!  September 30, 2009 08:42 PM
This goes out to anyone who has raced!All the big names you see on tv or mags started on a two-stroke!If they didn't it truley is a shame.
aye -dt 125  September 26, 2009 09:34 AM
for me 2 stroke still one of the most fastest strokes ever i ride with my dt 125 and still a honda 250 can't bit!!!!!!!!
Trevor -Woohoo! 2 stroke!!  September 22, 2009 05:47 AM
03CR250R vs 04 CRF450R. Simple acceleration & top speed race (FROM STILL DRAG & FROM 3rd GEAR DRAG) 2 stroke wins. Every Time. (*personal experience*)

I wish Honda still made 2 strokes... :(


It ain't fast.....without mixed gas!
DT -4stroke What!!!  September 7, 2009 08:20 PM
I have read sooo much about 450f's being a better bike.Well it's not true!If you take a yz250t any year after03 and compare you will see there is no right or wrong.I have a 04yz250smoker with a list of parts too long to go into and the end result is $$$.A 450f has to have 200ccmore to race against it!Oh as far as the cost about 450$$!!!
vince -nice  September 2, 2009 01:30 PM
i like that bike!!!!!!!!!!!
joe -gilera  September 1, 2009 05:10 AM
i have a gilera runner sp 50cc i then brought a malossi bore kit which was a 70cc/ i also brought a 21mm malossi carb/ i also brought racing reeds/ a bigger manifold was also added/ a racing crank shaft and bearings/ are in the engine aswell it has malossi variator rollers/ racing centrifugal clutch/ iridium sparkplug/ a bigger better racing exhaust system/ racing electronics/ cevlar racing malossi belt/ i use putoline racing sysnthetic 2t oil. by the way this bike is a 2 stroke and made in italy so the engine is strong and parts are prety cheap look at some gilera runners on youtube you will be preety suprised on how power pull mopeds and scooters can actually be when tuned etc. another model of the gilera range is the runner sp 125 saddly gilera dont make tis type no more because beying a 2stroke they are quite smokey so the euro laws came out so they were disscontinued but was swapped to a very slow 4stroke they also made a 180 cc model that was also a 2strok and fast. with the 125 model you can also buy a malossi bigger bore kit which will make the bike a 172 cc put it this way when fully tunned these bikes will do about 125mph i think for a scooter that is fast dont u think. about my bike i test rode my bike after easing the piston ring it the bore after doing so i test rid my bike on a straight remember its a now a 70cc i got a top speed of 110mph remember 50cc bikes only go a top speed of 30mph

ricky -cr 250  August 28, 2009 05:25 AM
hi i think 2 strokes are the best they are very powerful and i hate 4 stroke bikes they are sluggish compared to a 2 stroke lol.i grew up on 2 stroke bikes since i grew up on them i now have a cr 500 2001 model. i raced a 450 my cr 500 pissed all over it. it is a abeast and purely a supierior bike if you have got a 250 then look for cr 500 if you want more power seriously this is the bike. i cant understand why they have taken these beasts of the track. then swapped for a 450 machines theres no match to a 500 in mx
JC -2010 Yamie 2T  August 24, 2009 10:44 AM
I think Yamaha already had its press launch for the 2-strokes (not 100% sure). They should be out asap.
kiko -Re: JC's feedback  August 22, 2009 04:53 AM
Thanks man for the response!

Sure i just hope they do allow to race them. Any scoop as to when the 2010 YZ250 2T model may (or may not) come out? Or we have to wait and see after the All-Japan MX Nationals Championship this September '09?

Ciao!
sout sider -hp/power  August 18, 2009 11:58 PM
thats not right! my dads '04 yz 250 puts out 50.1 hp while my uncles '06 crf 450r puts out 46.7 hp! (mabye your 2 stoke wasnt tuned...)
south sider -power  August 18, 2009 11:52 PM
thats not right!!! my dads '04 yz 250 puts out 50.1 hp on the dyno while my uncles '06 crf450 put out 46.7 hp! you guys got it all wrong! (or mabye the 2t need tuning...)
JC -RE: kiko  August 17, 2009 08:31 AM
I think the stock YZ250 is way more powerful than the 250F bikes. It feels like a lightweight rocketship, but they're just two different breeds. We'll see if they let the 2T race with the 4T in professional racing. If so, my guess is that they'll be more than competitive and a favorite choice of the racers.
kiko -hp and torque on the YZ250  August 15, 2009 01:43 PM
Hi JC, the bone-stock YZ250 makes 46.8 hp at 8800 rpm (doesn't lose 5 ponies until 9600 rpm; in fact, it is still making 45 hp at 9100 rpm) and put outs 30.6 ft-lbs of torque, quoting MXA magazine.
kiko -for JC Hilderbrand  August 15, 2009 01:38 PM
Hi JC, what were thoughts about the YZ 2-stroke bone-stock? A lot of power than the usual anemic 250F you reckon?
RP121 -Amateur speakin up  August 14, 2009 10:09 AM
I had a 2005 crf250r for 4 and a half years, great bike BUT it cost me an arm and a leg...six months ago bought an 09 YZ250, Love it. My laptimes have eclipsed to much faster than on the F. Bigger jumps are attainable now. I am looking forward to the maintenance as it will be a $150 affair. I raced it recently, holeshot, win. Much better performance than on my crf250. I had an advantage over the four strokes. Oh if you cannot figure out premixing, get a Ratio Rite dude. It is a better bike for the average Joe, such as a working college student such as myself. I just dont understand why everyone gets so bent out of shape when people say that a 2 stroke is better bang for buck. get off the couch, go ride the dang bike. Unless you gotta mechanic or buy a new F every year, I suggest you check out Yamaha's YZ250. Great suspension, very good predictable handling, smooth strong engine (I holeshot 450s-not a lie), cheap to maintain, and IF something catastrophic happens you wont be out $1500. dont say I didnt warn ya.
jp -what r u thinking  July 8, 2009 06:22 AM
2strokes r the best they keep u ready to ride hard,fast and at your best
JG1 -2Smoke  June 8, 2009 03:01 PM
Been riding 2Strokes right under 20 years now, started on a brand new 1990 red/white YZ80...only 4 strokes i remember seeing were the XR's, but most of my uncles during this time were riding the 500 2strokes. Back then, this was the 2stroke generation, these were the bikes to ride, this is all we knew growing up. I have ridden both the 250F/450F, and while these are great bikes they are not enough to make me switch. The 250F is too docile, and the 450F has different characteristics I just don't like (weight, engine braking, starting issues, Maintenance $, etc.) based on my riding style in single track conditions. The 450 is smooth, and far from intimidating like most say...having grown up on the 2stroke powerband, I feel I can abuse a thumper even more...it's predictable linear power is just that...predictable! I can blow up a 250F, and ride a 450 thumper like my 2stroke, but it comes without the grin. It sucks Manufactures have eliminated the smoker, because it is trully sad to see this generation "learn" how to ride on a thumper. It's like taking away dirt bike history. I will tell you this from experience, a 2stroker can ride your thumper like his 2stroke, but isn't funny that a true thumper CAN'T ride a 2stroke like his/her thumper???
taekwondojunkie -bens comment  June 3, 2009 09:14 AM
2 strokes are not all that much cheaper than 4 strokes.plus the 2 strokes MAKE you earn their respect.
ausmx -whadayatalkinabout  June 2, 2009 11:31 PM
Um... Do you really think if 250 2T's were faster than 450F that all but the YZ and Kato remain? I have ridden and raced all these bikes. I raced 125's and 250's long before there were 250fs and 400, 426 and 450Fs and I will give the 2T one tick... In loam/sand I kill my lap times on a 250 2T compared to a 450F but i think it comes down to the weight difference and not getting as stuffed on the 2T... Im an A grade rider so if you were comparing a B or C grade rider maybe they'd be faster on a 450 in such conditions... BUT... the reality is that 80% of people that buy these bike are not A graders AND even more than that... A 450F/250F is a better overall bike for the extremely varied conditions that are found on MX tracks around the world... I love 2T's and if all the tracks I rode on were sand/loam i'd still have a YZ250. For now Ill keep my CRF450 but as I say, once you've loved a 2T that love will never leave. I got a KTM 300 EXC in the garage as well for those X country days and general ball tearing fun!!
Ben -WTH?!?!  May 31, 2009 02:25 PM
2 strokes SUCK!!! What are you fools smokin? premix? 2 strokes suck front to back, top end to bottom end! They are cheaper, and thats the ONLY benefit.
jeff -2002 suzuki rm125  May 22, 2009 07:03 PM
just picked up a 2002 suzuki rm125 and i love it so much i used to ride my dads 2006 honda crf250x and this thing puts it to shame i really hope they will bring two strokes back, plus you can mod a two stroke way more then you can mod out a 4 stroke. ( 4 joke , 2 smoke) thats what i say!!!!
taekwondojunkie -2strokes  May 21, 2009 01:14 PM
im 39 years old.the last time i jumped on a dirt bike was 1984.i have a friend that rides flat track bikes.hanging around him put a fire under my a!@#.and all of a sudden im riding dirt bikes.so i go out a find me a "99" yz250 2 stroke.got it for $1700 and its a beast.after riding it all the time i test rode a 450 four stroke,i still got a little to learn about dirt bikes but i do know this...four strokes are a cool ride,but the next bike i buy will certainly be a 2stroke.i simply love the off the start power they have.and from what i understand they are a WHOLE lot cheaper to fix.so im giving MAD PROPS to the two stroke.in my opinion the only thing that gives the 4 stroke the edge,is that you dont have to worry about premix.
brad -2 strokes rock  May 19, 2009 08:09 AM
4 strokes are the best hell they only need 2 times the motor and are 2 times the weight why dont they put the money into a 2 stroke 450 and neglect a 250f lets see what the 4 stokes got on that now there not so good without a handicapare they. The way i see this as is the dirtbike companys taking candy from kids at the candy store my 4 stroke buddy blew up his bike he siezed it and with how much it was going to cost to rebuild it, it was cheaper to buy a new bike. I just rebuilt a 2 stroke with worse problems and yes the bike was a 2001 without any rebuilds ever and my four stroke buddys was a 2005 and he barely put 100 hours on his bike but anyways it cost me a sweet 700 bucks with tools prices included.
shrubitup -you need an F on the end of a 250??  May 5, 2009 10:51 PM
This is similar to Hildebrand's review of the 2009 KTM 250XCW. He doesn't know what to make of it. It's just not his thing. THAT'S FINE but don't go throwing your preference into this. What about the rest of the bike besides the motor? Good or bad? Who knows because you so simply dis the bike because it's not an F bike.
mx4lyfe -2STROKES!!!!!!!!!  May 4, 2009 11:28 AM
i had the crf250r. yeah it was ok and i had to keep puting more and more money into it. so i bought a 2001 cr 250 damn. that thing runs better. more power and every thing u will ever need. BRING THE 2STROKES BACK!!!!!
Bill -2-strokes vs 4 strokes  April 20, 2009 07:42 PM
To me you steer a 4 stroke, but you drive a 2-stroke. So, if you want comfort and ease of operation ride a 4-stroke but if you want raw power drive a 2-stroke. It's like an automatic verses a standard sports car, both are fast but built for different owners.
sally -Ok well  April 20, 2009 02:35 AM
I'm the only one here that likes four strokes too? Wtf lol. I do agree that for pure shits and giggles off road riding, or if you are racing two strokes are going to be faster, up to about 500 cc. After that the abrupt power delivery will just pull the front wheel up and you won't actually go anywhere haha. But anyway for enduro trail riding, rock crawling, ruts, hill climbs and all that stupid shit (a very different kind of riding), four strokes will eat the smokers any time. Anyway I've ridden at least 15 different bikes, and I have to say the one that put the biggest stupid grin on my face was a little Kawasaki KX85! You gotta love a bike that weighs like 100 pounds and can power wheelie in fourth gear. I giggled like a god damn school girl the entire time I rode that damned thing haha. Jumped right on, got it into the power band in first gear, pulled a huge wheelie, let it back down, did the same thing in second, third and fourth, several times. Hahahah I could do that all day long. That's the only reason I would ever really want a two stroke though. I would just takie it out and pull wheelies all the time.
Riley -2 stroke come back  April 13, 2009 09:55 PM
support companys that continue that to reasearch 2 stroke motors!!!! they are the best why every one fails to realize this is beyond me??? they can burn cleaner with out a cat so imagine what they could do if they actually spent time to research them Evinrude is one of the few companys researching how to keep the 2 stroke alive!!!
pinned927 -eeeeeyyyyyooooot  April 12, 2009 08:40 PM
I sacked up a while back. I had 3 450's in my garage and said ya know what? eff it. i wanna run caster oil and triple clutch every corner again. I sold my least expensive (least liked) 450 and bought a 250 2 stroke 3 weeks later. After that, i seriously didn't ever have a desire to ride a 450 again. Now i'm gonna sell another 450 and get a 250f. they're all fun
tyler -motocross  April 10, 2009 07:11 AM
I suck at motocross i just like to ride lololol
bryan -just bought an 09 yz  April 8, 2009 08:43 PM
i have been riding 450's for a while now, before that i rode 250f's and have always been a smoker fan, recently sold my 01 cr 250 and my 450 to buy the new yz, i race competitive motocross and some tighter arena cross style tracks. hands down being a blue collar everyday guy who rides, the 2 strokes make since, cheaper, faster, and the fun factor is off the charts. its like a rocket ship waiting to take off. and who can beat the sound, smell and feel of a smoker when its pinned. i made a decision over night. im bringing it back to the smoker in hopes my friends might follow along. everyone, write your letters, go buy a smoker and lets get these things back where they belong, on the podium.
jake -wtf?  April 1, 2009 07:25 PM
i have a four stroke 250f that i bought brand new last year... and honestly i put so much money into that bike just to keep it running..and it seems like im not getting any power out of it.. im trying to sell it for a 250 two stroker..im sick of that pile of junk..
johnny man -2-strokes  March 20, 2009 08:11 PM
I have a yz 2-stroke and I love my bike!!. The kx 250f I had sucked!!!. The 4-strokes have a weight that I will never like,and had I known it had cams,chain,valves,ect,ect,I would have never bought one!. What a waste of money when I could have bought a RM 125 2-stroke. This industry 4-stroke scam is like AIG and their corruption. Motocross was never designed to be a sport for the well off. It is a sport that the average 9 to 5 person could work all week, then go racing on the weekend. Not worry if he can afford to. YAMAHA,KTM, keep making the 2-stroke!. I also noticed more pros are going over the handle bars of these 4-strokes. I sure don't want one landing on me.
JD -bring them back!!..  March 18, 2009 07:57 PM
2 strokes are better bikes!, they give you better skills, less weight, easiest maintenance! and lotss of more advantages!! please bring them back!.. began buyin your 2 stroke and u will not regret it!..
randy -two strokes  March 18, 2009 06:53 PM
fast, cheaper not cheap, takes more practice to master all part of the fun, much easier to maintain, quiter, instant throttle response if you have the nerve, the person who has the most fun wins.
rpm -YZ250 vs YZ450F vs YZ250F  March 15, 2009 06:56 AM
Unbelievable that the article states that YZ250 against 250F is more realistic. A 2 stroke bike is much harder to ride, but as the Japanese Yamaha factory representative said: "4 stroke is just a fashion statement, you can only go really fast with a 2 stroke" Obviously, it all depends on a rider, but definitely a 250 is not even in the same universe with the 250F. Rode on both, 250F is a joke compared to a higher category 250 2T. 450F is a great bike, but with a great rider easily can be beaten with a 2T. Maybe because of the higher torque feel on a 4T that everybody thinks that 2 strokes are weaker, but people need to understand that it just requires a different riding technique and then it is definitely faster than anything in the world. :)
Andre -250F ? pphhhh  March 5, 2009 06:03 AM
These 250F's are pathetic. They need an expensive engine rebuild after 60 hours and you have to rev the piss out of them if you want to go fast.Not to mention they have no bottom end power whatsoever. BRING BACK THE SMOKERS
mototony -2 vs. 4  February 23, 2009 11:49 AM
My KTM 300 2-STROKE makes plenty of torque in a broad RPM range. My motor never chewed itself to bits like my friends 4 stokes' have. My bike is MUCH quieter than the 4 strokes I hear at the track and on the trail. Once rolling my bike feels lighter as well. So lets's see -less initial cost, less maintenance, less moving parts, less noise, less weight, and more fun when the throttle is twisted. Tough decision. As for EFI, you can't beat "automatic jetting", but EFI can be, and already has been adapted to 2 strokes. There are still companies out there working on 2 stroke technology and I am surprised we do not see them in cars by now. If the govenment "experts" ever ban 2 stroke dirt bikes, I will take out a loan and by as many as I can afford before they are outlawed.
2Smoke -Let's be honest  February 22, 2009 07:17 PM
4 strokes are gutless compared to 2 strokes.

Nick West -American 2 Strokes  February 19, 2009 08:16 AM
Hey nice to see your American AMA has done at least something to re-dress the balance for 2-strokes in the amateur classes. In Europe they are looking likely to bring the displacement in the pro series of FIM Motocross so its 250cc 2 strokes against 350cc 4 strokes (dropped down from 450's) - in order to redress the unfair power the 450's now have due to all the R&D done on 4 strokes in the past few years. see this link http://www.motorcyclenews.com/MCN/sport/sportresults/mcn/2007/december/dec17-23/dec2307ktmback350ccmx1plan/ Im in England (UK) and I have a 2 stroke KX 250 actually Road Registered! I don't need to worry about which bike is 1 or 2 seconds faster on a track - I ride for pleasure and fun on the open roads here. I think we are the only country in the world where you can road register these bikes without any modifications (we just have to put a number plate and a horn on it!) - fully insured and taxed - I'll be on it this weekend and I LOVE my 2 stroke!

four strokes are for girls!
Bike Dude - 250 -Colton what the hell !!  January 30, 2009 10:00 PM
Your coments about 4 strokes still being "better" is ridiculous. The smokers rule supreme in the offroad segment, especially if you see how many of them get podium titles in races like Erzberg,ISDE and Romaniacs. Plus a 250 smoker would eat a 250F alive any day, who cares if the 250F makes broader power, the 2 stroke is making 10 more horsepower for Gods sake !!! Thats 30 percent more than a 250F and its cheaper to run to.I hope you guys have fun doing your 700$ rebuilds when your valves go south.
Dan -2-strokes rule!!!  January 12, 2009 06:53 PM
#1 Mixing your gas is not hard #2 Goin fast on a dirt is not the bike, its the rider #3 2-strokes are much cheaper to maintain #4 It depends on your personal preference I love 2-strokes especially 125's and I'm 46 yrs old, 175 lbs. It just comes down to what you like more. If you can afford the rebuilds on a 4-stroke then go for it. But for me it makes more sense to ride a 2-stroke. I do like riding 4-strokes, but I dont want to pay for one. The 2-stroke motor, IMO, is the cheapest, most powerful, easiest to work on, and the most efficient motor there is, hands down.
Willy P -Something to say  December 29, 2008 08:36 AM
I am glad that the YZ 250 was brought into the test with the other 250F's. If they are able to race with them in the amateur class then maybe they will change the pros. A 2 stroke is sooo much easier to maintain and then cheaper to operate on top of that. This bike could help keep some people in this sport like myself who can't afford the upkeep on a modern 4 stroke but love to ride and race with the ability to stay competitive. Long live the two stroke!
bob -2009 yz250  December 26, 2008 02:35 PM
well to me its about being more focused and having more fun and being fitter to ride a 250 2 stroke. all these test riders only rode the bike for like 1 day and if they had like a couple of months or even a year to ride the bike they would all change their mind and say its pretty competitive, all you need to ride one fast is to know the bike, if u know the bike you can push it and know what it will throw at you. and how can mixing premix be a pain in the ass, at least you will know its got some fresh premix that will make the bike run like a million dollars and have some blue smoke that will choke the competition :)
blaze -2009 2-stroke yz250  December 19, 2008 08:18 PM
THIS IS A HUGE THING! IM MIGHT GET ONE MY SELF!!!
John -I have something to say...  December 19, 2008 06:09 PM
How could you say, 'make sure it's got an 'F' at the end of 250 if you're racing a lites bike?' It's that attitude, sir, which is the reason why 2 strokes are dying out. Well maybe not, but still... 2 strokes are a lot more fun than 4 strokes. I own a kdx220 and if I was going to get a new bike it'd probably be a yz 250 or sx 250. It's a good size between 250f's and 450f's and it's less maintenance, I hear. Cheaper too. In your closing you should've said, "if you're a wimp who can't handle the 2 stroke and would rather be lazy on a thumper than go for a 250f." I'm just poking fun; but I understand what you're saying about being in the right gear. With a 2 stroke you need to be revved out when you're hitting corners to get the most out of the bike, so it's more difficult in the sense that you don't have that long pulling traction that a 4 stroke has. Mixing the right amount of premix oil each time can be a pain in the ass, too.
JC -Nothing to Say?  December 17, 2008 04:20 PM
Come on, folks! No comment on the 2-stroke. Hell, it was all our testers wanted to talk about. This is a big deal for amateurs... Isn't it?
