2009 Yamaha YZ250 & YZ125 First Ride

2009 Yamaha YZ250 and YZ125
The 2009 Yamaha 2-stroke motocrossers aren't all-new, but at least they're here! The YZ250 and YZ125 are the last of the Japanese 2-strokes.
There's just nothing like the smell of a 2-stroke dirt bike, or the sound for that matter. The mixing of pre-mix oil and race gas, combusted and then expelled from the shorty exhaust canister of a 2-stroke motocrosser is the original testosterone perfume. While I'm sure it wouldn't be good for my health, I could pump the exhaust straight from the canister of the 2009 Yamaha YZ125 into the vents of my house; living immersed in the glorious odor, and would be a happy man. My girlfriend, on the other hand, might not be quite as happy. But if you grew up riding 2-strokes like I did, I'm sure you wouldn't mind either.

Equally as intoxicating as the odor is the sound. The high-pitched scream of a 2-stroke climbing a fourth-gear-pinned hill will raise the hair on your arms unlike anything else. While 4-strokes are deep and throaty, sounding equally as gnarly per se, it's just not the same. This is why when the invite for Yamaha's 2009 YZ125 and YZ250 intro rolled across my desk, instead of giving it to one of my guys, I personally jumped at the chance. It's been a long time since I've heard that high-pitched scream, and I've missed it...

Sadly, 2-strokes are a dying breed. At one point they were the only option for an MX'er, but with the improved technology of 4-strokes and the tightening of environmental regulations, they are going the way of the dinosaur. With Kawasaki, Honda and Suzuki discontinuing them, Yamaha is now the only Japanese OE still producing the smokers. European brands, most notably KTM, still do as well, but the list is dwindling. Sad, very sad.

In the pre-ride technical briefing, Yamaha made it well known that they want to keep making 2-strokes for as long as possible. Their history is with 2-strokes, as its first-ever motorcycle was a "ring-dinger" and, in fact, for the first 15 years it's all the tuning fork gang produced. Problem is, they can only make what people will buy, and sales have been declining steadily, thus if things don't turn around, it may have to follow the competition. I can tell you one thing, after riding the latest YZs, it'll be a travesty to see them go - they are amazing machines.

Snappy power and proportionate grins characterize the YZ250. Our testers were giddy to smell pre-mix again.
Snappy power and proportionate grins characterize the YZ250. Our testers were giddy to smell pre-mix again.
Because the cost of making a whole new model for something that has seen declining sales is far too high, for '09 the YZ 2-strokes only received a host of small changes. Aimed primarily at saving weight and sharing a parts bin with the YZ-F line, nothing mechanical has been changed on the '09 YZ models.

The front tire on both is now the Dunlop D742FA, which is also used on their YZ450F, and is designed for improved traction in a wide variety of conditions. The rear tire on the YZ125 is the same D756 model, but is now almost a half-pound lighter and has been re-designated the D756G. Also lighter is a new front brake hose holder on both machines, made of aluminum as opposed to steel. They both get gold DID chains, while the seat cover surface now features a new pattern that has more grip.

That wraps up the changes, but it should be pointed out that just because a lot hasn't been updated doesn't mean they are any less advanced. They still feature the same top-of-the-line components as their 4-stroke counterparts: KYB suspension, aluminum frames, titanium shock springs, titanium footpegs, adjustable Pro Taper handlebars, wave-type brake rotors, quick-adjust clutch, etc. By no means are they second-rate. In fact, they're quite the opposite.

Some other key points not to forget: The YZ125 is $750 less than the YZ250F and the YZ250 is $800 less than the YZ450F. Weight is quite a bit less as well - YZ125 is 18 pounds shy of the 250F, while the YZ250 tips the scales 12 pounds less than the 450F. The Yamaha YZ250 is now also legal in the Amateur Lites class, going head-to-head with 250F equipment. They are also legal for all $12.7 million of contingency money Yamaha has posted for '09.

There s nothing quite as enjoyable to flick around as a true tiddler. The YZ125 takes a certain kind of rider to appreciate its nauances in this world of 250F machines.

For testing duties, our boy, former pro motocrosser, Matty Armstrong, joined yours truly, plus some guy named Grant Langston. I hear he's kind of famous and won something called the Outdoor Nationals? Sounds like it should be on the fishing channel. Either way, he sure is fast! After inhaling the noxious fumes of pre-mix for an entire day, here's what found its way through our smoke-filled brains and onto our notepads.

"Two-stokes aren't for sissies - they're hard to ride fast, requiring much more commitment and skill, but when you get it right, there just isn't anything like it. The feeling of absolutely ringing the living daylights out of the YZ125, constantly on the throttle, is almost intoxicating. It really is something every rider should feel at least once in their life. It had been a long time since I've felt that, and while it took me all day to get to that point, when I finally did, it was downright awesome!"

"It's been since the beginning of 2004 that I've ridden a 2-stroke, so it was really cool to get back out here on one. They really are a lot of fun. For a lot of people these are the perfect bikes. They are easier to maintain and the 125 is a good stepping stone for a young rider coming off an 85. A 250F is a big bike and it's a lot easier for a kid to go from an 85 to a 125 than to go straight to a 250F. I think people forget how hard and expensive 4-strokes can be; if you're not an engineer they are hard to work on, too. But 2-strokes are so easy and cheap, they're a great option.

Amateur rules now reflect the changing times and 250s can run with the 250F machines.

"The 125 really impressed me, it had great bottom end. I typically like to lug the bike through the corners and it did great. When I got going on the thing, it revs so high I always thought I was going to blow it up, I wasn't used to it, but it look the abuse and kept on going no problem. So much fun. There always needs to be a place for 2-strokes if you ask me. It's where I came from and I've had a great time out here riding them. I think people forget how good they really are and I think it's cool Yamaha still makes them."

"It's been a long time since I've heard that sound and smelt that smell. It was kind of odd, when I first went to start it, the kickstarter on the 125 was so short and easy to kick, but I was kicking and kicking and kicking and it wouldn't start. I forgot you have to give them a little gas, which is the opposite of a 4-stroke. But once I figured it out it started the first kick, and did so the rest of the day. They are just so easy to use - easy to start, easy to work on - everything about them is a lot less complicated than a 4-stroke.

"Both of these bikes worked amazingly. They were almost hard to ride at first, as I was used to being kind of lazy on the 4-strokes, but on the 2-strokes you really need to be on it. But once I got use to them again I remembered just how rewarding it was. They do everything really well. The 125 is so light and nimble, you can literally put it anywhere you want. It's almost too easy. The suspension felt completely dialed in on both bikes, they felt almost perfect. And the throttle response on both bikes were equally as good, especially on the 250. It's instantly there - so precise. Both bikes worked flawlessly, I haven't had as much fun riding as I had today in years!"

Grant Langston was on hand to enjoy the amount of fun 2-strokes still offer.

After spending a full day riding the last of the Japanese two-stokes, we've come to the conclusion everyone needs to go out and buy one, right now. We are commanding you to do so! Well, obviously we're just kidding, but we are hoping people come around and see how good these machines really are. To see them go would bring a tear to our eyes. We have already put in a request for a long-termer and will proudly take it to the local MX track to fly the 2-stroke flag with pride!

Ren Schmidt -Pres. of Revanche2strokes.com  December 14, 2010 06:37 PM
4 stroke fan or 2 stroke fan, we all should be allowed to decide based on fair competition, not skewed to suit the big 4's agenda to shove the inferior 4 stroke down our throat. And it is inferior, if it wasn't, it wouldn't need a double displacement advantage. Ask yourself this question, if the 2 stroke was as inferior to the 4 stroke as the 4 stroke is to the 2 stroke, would the big 4 and the AMA make allowances for the 2 stroke to be twice as big, so it can compete and everyone can be warm and fuzzy? There's no way on Gods green earth, this would be allowed. Everyone would be crying for the death knell for the 2 stroke, on the grounds that it's so slow that it can't compete and should just go away. Yet, we "help" the 4 stroke everywhere possible, we even go so far as to brainwash the world into "pitting" the 2 stroke naturally into races with the twice sized for 4 stroke as second nature, not only in racing, but in tests and everyday conversations. If the 4 stroke is really the best and the ruler of the 2 stroke/4 stroke battle, let it rule because it's the best when competing head to head and if it does and win, then it can say it's the best. Right now, it's only the best because it's competition has been hamstrung. Should todays pro baseball players be allowed to say they are the best homerun hitters when some of them are hyped on steroids and the old champions didn't have that available, or should they all be forced to play fairly and then, let the best man or machine win?
mike grady -2 st fan  November 24, 2010 07:25 PM
As everybody says 2 stroke mc are slowly fading out, but I am still very convince of its monstrous torque. I also have an underbone mc 2 stroker Yamaha 125zr w/ pure 6 speed power & speed. Hopefully companies who are still producing 2 stroke mc will come up w/ new slick designs.

Loooooooonnnnnnnnngggggggg live 2 stroke power!!!!!!!!! U rock my world..........

Smitty -2 stroke sales are on the rise!  August 31, 2010 06:31 PM
From what I read gentlemen, and the sales #'s the deallers tell me, 2 strokes are slowly making a comeback and some manufactures are debatinf on bringing some of their models back to the states. I think that 4 strokes are more of a fad. However, yes, they are easier to ride on the track but if people would stop dreaming of making a career of racing and just race whats more fun, cheaper, and man up on a little more arm pump......then they will realize (and now they are) that 2 strokes ARE the future and the mags need to continue to talk good of them as they've been in the last 2 years which greatly helps! 2 strokes will never be as they were for sales figures, but they will never die and I think they will slowly start to be R&D again.
Smitty -Chase's YZ  August 31, 2010 05:15 PM
Dude, ya gotta lower ur asking price cause I was at the dealer and can get a 2010 for $6,360....out the door! ........500 off and 500 from Yamaha. No Joke..... Willows in Cheshire, Connecticut. I'm going for a YZ250 or a new 2011 KTM 300 XC-W for $7350 out the door.

2-Sroke Man -Love 2-Strokes  March 24, 2010 03:28 PM
I love the 2 strokes, screw the 4-strokes no power compared to 2-strokes. I used to have a xr100 and sold it as soon as I rode my friends yz85. And now I saving up for a yz-125 because I need the power.But I only have the money for a used one so I'm just looking around. I love the 2 strokes. Keep making them Yamaha!!!!
Raymond -2 stroke is the bomb!!  January 14, 2010 10:41 AM
I have a 2000 kawasaki 125 2 stroke and its not even close to anything else u have so much snap in it and it smells so awesome, Ya don't stop makin 2 strokes!!
Grant Yzinger -2 Stroke YZ 250  December 18, 2009 10:22 AM
Started riding when i was a kid on a RM80,next bike was a CR red rocket (those years this was a state of the art machine),always wanted a YZ 250 though.Life happened and didnt ride for 18 years.I bought a 2005 YZ 250 about 2 years ago.This bike is AWSOME.Without a doubt the most fun you can have with your clothes on.It surprises Every time i ride it,never a dull moment,awsome power delivery from start to finish.This bike wheelies in every gear without any effort,rides dunes,enduro,mx tracks without any hassles.Take a look at the results from the 2009 Roof Of Africa and if that does not set you straight then nothing will.1st - 6th place finishes in 250 class all YZ 250 two smokes.YZ 125 1st in 125 class and the only 125 to finish the Roof.Mark my words the 2 stroke shall return,these 4 strokes are simply not FINANCIALLY viable unless you have a sponsorship or your daddys a millionare or really into the sport.This will be the downfall of the 4 strokes.LONG LIVE THE 2 STROKES.
dakota bronson -2 strokes  December 2, 2009 10:44 AM
I love yamaha's but i ride a kx250 i also have a ttr 125 they bothe have there good and bad things with the kx i have power speed and a power band it is great but i work on it all the time and the ttr i dont have to wait for a power band it is always there but its not very fast. I think they should keep making 2 strokes.
Andy K. -Bad bike  November 13, 2009 08:16 AM
I got a 2005 yz 125 a little while ago. It is crazy fast. I was riding a 2007 TT-R125L that has no torque, you have to bounce it off a rock or something just to pop up a wheelie. Yz 125 nope, Half throttle forst gear stood straight up. The yz 125 was my dream bike as soon as I saw them scream. Having this 125 sitting in the garage during the week kills me. I ENJOY ROOSTING THE 250F's
MT Smoker -Shop around....  November 12, 2009 06:36 PM
Just ordered my 2010 YZ250, yes w/o the F. Tried to get my local Yamaha dealer to get my one, they said that 2-strokes suck and try to offer me a 2008 YZ450F for 5,000.00 new. I said that I wanted a 2-stroke, they then made offer on a 2009 YZ250 for the price of 6,995.00. After thinking about it, the MSRP was 6,599.00 for 09... I felt like I was going to get ripped off, so I called some other Yamaha Dealers in my State. One of them said that they could get me one in Feb of 2010 when they are released and save me some cash. Needless to say my local dealer lost in a sale of not just one but two dirt bikes, cause my wife wants a dirt bike too. So now we have to drive 4 hours to the Dealer that will work with us, but who cares right... We are getting GREAT deals and support from a dealer out of our town... If you have problems with your own local dealers like we had, shop around... You might find what your looking for and be happy like us...
Ryan Dey -A Call to Arms! The Two Stroke Manifesto!  November 12, 2009 05:05 PM
Everyone should read the November 2009 Motocross Action article: "Two Stroke Manifesto" By Jody Weisel The article sums up everything there is to say about the two stroke vs. four stroke debate. You won't want to continue pouring your hard earned money into a four stroke after reading this article. They are inferior machines. A four strokes requires twice the cubic inches (and 2 more strokes) to produce what a two stroke produces in horsepower; not to mention the weight and amount of moving parts factor. It's all been designed to suck more money out of a clueless and gullible buying public. Stop buying the four stroke and the manufacturers will be forced to rethink their decision to eliminate the superior design. Dirt bikes are supposed to be fun! Four strokes take the fun out of riding a dirt bike.
MT smoker -2-strokes ROCK....  November 9, 2009 06:47 PM
Who in world would waste money on a THUMPER??? It has always been knowing that 2-strokes make more POWER and are LIGHTER with less mass of moving parts. Could you think what 2-strokes would be like now!!! If the big four had put the same amount of money into 2-strokes???
Jordan -2009 YZ250  October 23, 2009 10:09 PM
Have raced my 2009 YZ250 3 times (6 motos) have goten the hole shot every time! Not sure if I ever got a hole shot on my 07 CRF250?
Always have had honda's, now I'm true blue YAMAHA!
DT -4stroke What!!!  October 18, 2009 05:33 PM
I have a 2004 yamaha yz250 with too many extra's to go into.With that said I ride with 250f's all the time and they simply have nothing!If they have to put my bike into 450 class where are allowed to build the motor 100% bigger to get the same results something is wrong!I simply ask to read the november 2009 motocross action magazine.Two strokes are not going anywhere.
chris -96 cr 500  October 7, 2009 08:22 PM
nothing will beat my 1996 cr 500. this bike will kill 450 four strokes,eat 350 banshee's ,and murder 250cc two strokes. it's almost to much power.
Barnes -if two strokes die i will cry for sure bye honda cr's least we forget =(  September 15, 2009 11:19 PM
Yz is hottest bike around. I own a kx250 and it was ok so much top end more then yz but not good for jumping. yz however has nice band and great jumping balance. in my opinion my bike tended to be not balanced i rode my friends yz 250 and wow i could tell this bike was tracking straight and pulled great. easy to jump. always did the , brake hit in air to bring front down on my bike more then needed but yz sounds great not loud engine clanking and crap just a great tone.
Dirty Dug -2stroke heaven !  August 21, 2009 05:53 PM
I grew up on 2 strokes and will keep riding them till i die.
I own an RZ350 an IT250 a 1999 WR250 and a 2008 YZ250 and love them all. You cant beat the adrenilin rush you get from that crisp throttle responce and hitting that savage powerband. I like 4strokes to but gimmie a stroker any day !

RAIDEN -YZ125  August 2, 2009 10:11 AM
Im going to be buying a 2003 yz125 instead of a cr125 because yamaha still makes them, honda does not. So i will be supporting Yamaha. Four strokes blow and two strokes go. Yamaha should only make two strokes, why change a good thing. Its nice to see a company like yamaha who listen to the custommers and keep maken the two strokes. KEEP UP THE GOOD WORK YAMAHA

my 02 yz125 is a great bike all around, cheap and easy to maintain and the smell and sound of it is one of the highlights in my day and the power is amazing and the adrenaline rush is an addiction. my friend has an 03 cr250 and the thing is a beast and alot of people r afraid to ride it. keep 2 strokes in the picture and show the lazy 4 stroke riders how its done
Tom Hoogeveen -rm 80 rule  June 8, 2009 05:06 PM

Hector -four strokes suck  June 7, 2009 09:24 PM
I currently have a quad and ttr 125 and i am miserable ever since my cousin let me ride his yz 250. These bike are simply amazing and should never be discontinued. Im trying very hard to sell my two bikes so that i can get me a yz 125. And those people who say they like the steady power of a four stroke and this and that they are a pack of wuzzies, and these other losers who say they are damaging to the enviroment they can suck it because we do far worse things to posion the enviroment so stop chewing on the 2 strokes ass

Pinoy -2 Stroke  June 3, 2009 08:49 PM
Philippines learned to ride motocross with 2 stroke, the sound is really nice to listen it is like a music that the rider needs to make it in good tune, the power is amazing... I hope it will remain.. thanks CR 250 1997

Corey Friendt -2001 YZ250  May 28, 2009 08:09 AM
My 2001 YZ250 is nuts! There isnt any better feeling in the world then going out on that track and being the only 2-stroke, but also being the most noticed. Back in the day all there was, was 2-strokes and every now and then a 4-stroke, and to see how over the years it has made a total turn around with there being all 4-strokes, it makes me sick. I've had my yz250 for about 6 or 7 months, and I am still scared crapless to give it full throttle cuz it's so fast!! KEEP 2-STROKES ALIVE!! The smell, the sound, the cost, the enjoyment; It's all worth it.
koltan macdonald -keep making the 2 smokes  May 25, 2009 07:27 PM
i am 14 and just got my first bike which is a 2000 yz125 and i love the power ban on these things they need to keep making these so i can get a brand new one in the near future
jim van dyke -2 strokes  May 24, 2009 10:34 PM
2 strokes are much lighter in terms of handling and throttle response. I think the 450 4s are fantastic bikes, but I'd rather be riding my KTM 300 especially on tight, fast mountain trail riding. It's quicker, it feels lighter, there's no arm pump the power band is unbelievable and most of all the 2 strokes are an absolute blast to ride. I hope the bike companies find a way to keep making them. I'm sure they would make a comeback.
Mark Nelson -yz 125  May 23, 2009 04:03 PM
I took 2 place over all at SpringCreekMX park in 2007 on a 2005yz125.In 40+B class and all the other guys were on 450s.I had so much fun with the sound of my bike in the corners that other riders look back at me and I would pass them.Quick light fast and easy to work on.Y would anybody want a 4stroke.Mark

AZ Vet Rider -Rekindled 2 stroke love affair!  May 10, 2009 03:16 PM
I grew up riding and racing 2 strokes. I got caught up in the new 4 stroke generation for the last decade. I am currently riding a crf450. I took my son's RM 65 for a quick ride in the desert the other day and that snappy little 2 stroke rekindled my love for them. I am selling my crf and buying a 2 stroke again. There is no doubt that the 4 strokes are awesome machines in their own right, but riding that little 2 stroke reminded me why I started riding to begin with. FUN! Not to mention I love that premix smell in the morning!
drzrider -about your plugs  May 9, 2009 06:25 PM
yes i do have a drz400 but i have a kdx also i like them both, anyway you need to change your gas / oil mixture if your blowing a lot of blue smoke put less oil but not too much less as to harm your engin. i think i run mine 44to1. also i know if i run mine too slow it will fal sparkplugs so i stay on it all the time. hope it helps
Mike -09'Yz 250 blowing plugs  May 5, 2009 11:15 AM
I bought a new 09 yz 250 last week and so far blew about 10 plugs.The bike is awesome overall but I can't seem to keep plugs in it. Does anybody have any idea of what this problem might be? and know how to fix it?
zach preece -my first bike  May 5, 2009 08:30 AM
no one will help me buy my first bike they say that they are to dangerous thay said i should get a four wheeler but i want a dirt bike yamaha yz 250
steve -2 stroke  May 2, 2009 04:12 PM
2 strokes are just better in every way, i ride a 1990 yz250 fast as hell, front wheel up in every gear. where can you change a 4 stroke piston and ring set for 79.99? no ware. The ride, cost and whole thing is much better than a 4 stroke, i had a go of a crf 450 and i honestly thought the yz was faster!! ok you have to stay on the power but i thought that is what motocross was all about!!! There is a saying. "if it aint broke dont try to fix it" was the 2 stroke ever broke? i think not. keep the real mans bike a live and ditch the 4 stroke
2strokerrr -yz250  April 28, 2009 06:04 PM
09 yz250----is a beasT! 4 strokes are 4 pussies nd they sound like the bike is farting the whole time. 2 stroke scream nd make the ride worth riding~!

Mitchell -go 2 strokes  April 21, 2009 03:19 PM
Go the 2 strokes. Its anoying that the greenies are so against 2 strokes. I mean there is bigger problems in the world. Aswell as the fact from recent studies which has shown 2 strokes are better on the environment overall then 4 strokes. Due to all the extra parts and parts which need to be replaced, the 4 stroke is a lot harder on the environment due to the poroduction of extra parts. Whereas the 2 stroke is quite simple to build and very rarely needs new parts. This far out weighs the amount of oil the 2 stroke burns over its lifespan. end rant
Pat Magron -Keeping what started the MX!!!  April 13, 2009 08:42 PM
2 Strokes are what started MX why stop there a blast of fun and theres almost reason they should stop making them. Besides the fact that those damn tree hugen bastards wont shut up and worry about somthing else like the car problem ir somthing.Keep the 2 stroke game alive and thats why i love yamaha and its yz125 that i cant regret geeting.
Carl the irish dude !!! -AWWW  March 24, 2009 02:43 PM
I stupidly went out and bought a 2008 crf250r i really regret it i shud hav stayed with a wing in 125 !!!
rpm -2 strokes are forever  March 15, 2009 05:16 AM
There is nothing like riding a 2 stroke. All this 4 stroke hype is just killing the true fun of motocross itself. I am not saying 4 stroke is not the future, since 2 stroke reached their peak in development (so as we are told !), but I believe a little more time and money invested into these great machines, the snapiness, sharpness, lightness etc. cannot be recreated with ANY 4 stroke machine, they are just too different. Live and let live. Do NOT kill 2 strokes.
Jacob Esler -Go 2 strokes  March 12, 2009 11:41 PM
I love the yz 125 its sik, but i cant really decide between the ktm sx 125 and the yz 125. But 2 strokes are sik they should keep makin them. All the juniors from motocross race them after just coming off 85s they should keep the 2 strokes alive!!!!!
ELLIOTT -YX250 TWO STROKE  March 11, 2009 09:44 AM
One of the best bikes ever. YAMAHA KEEP MAKING THEM. The average rider cant afford to keep them running.
Jahrides -Two stroke fever  February 25, 2009 09:05 PM
I just got into riding with a used 125 two stroke and love it. My buddies have been at it forever and burn up trails on modded out 450 four strokes that cost a ton of dough. I can definitely say the four stroke route is cost prohibitive and would hurt in this economy when it comes time for maintenance. Most of us seem to have more time than money and enjoy the simple wrenching. The sport will suffer the way our economy is headed if manufacturers don't offer affordable, powerful, fun options. The Japanese manufacturers are not stupid, and they could come up with cleaner two strokes if the EPA is the only obstacle. Riders on the pro and hobbyist level will bring back the demand. When I upsize, I'm headed for another two stroke. Thank you craigslist.
bude 150 -two strokes are amazing  January 30, 2009 08:38 AM
I ride a crf 150f and i am getting tired of it. I did have a yz85 and i regret getting rid of it. it is sad that yamaha is getting rid of the two stroke. Two strokes are the best.
Moto-Dave -Amen, Long Live the 2 stroke engine!  January 21, 2009 09:07 AM
I think that Yamaha must have some guilt about pushing the 4 stroke into the AMA which almost killed the better machine they helped revolutionize motocross with? It is sad that there are no more yellow, green and red 2 strokes to race against anymore. I have ridden Yamahas for decades and my son races, so he offers me his bike every year for half price and I never take the bait after I ride them. I first rode his 450 Yamaha and now his 450 Honda and say there is tons of bottom end torque, but where is the “SNAPPY” mid and over rev? I’m not impressed with them at all. I ride trails and ride with racers, so I have to be fast to keep up with my buddies. I choose a 1997 WR250 and had Jim Holley’s Dad (Al) install the long rod kit, bigger flywheel weight, Boyesen rad valve and Fatty pipe. It is extremely fast, but really controllable when putting around with all that low end torque. After all this work it seems it has around 46 or 47 HP or the same as the new YZ. I discovered it was fast when my son convinced me to race a desert race out in Adelanto, 2 out of 3 times I took the hole shot in front of all the brand new 450s of every color! My only flaw was to fall and place only 4th place twice. But we all know which bike is the best … it is the 2 stroke. If we could get Ty Davis on my bike he could do it. I plan on keeping the ole WR until Yamaha makes a brand new WR250 2 stroke again. When they do, I will keep this beauty for a backup bike since it has a California street license too. I am optimistic that Yamaha will make another WR 2 stroke because all they really are is a YZ with a wide ratio tranny, lights and a kickstand. Moto-Dave hitting the trails since 1969
Chris -I love the smell of Pre-Mix in the morning.  January 21, 2009 12:00 AM
This article needs to be blasted out to every MX website and forum!! It would be a shame to see the two stroke go away. I grew up riding a KX80, then a CR125s and now I ride an '06 YZ250 and it's just a beast. So much fun to ride. I'll never buy a four stroke...two expensive to buy, own and work on. What the hell happened!!? It's amazing what slick marketing can do.
Mike Del Duco -Why is it......  January 18, 2009 04:08 PM
Everytime I go to the practice tracks all of my friends are dying to take a spin on my 06 YZ125?? These are guys that have all of the latest 450F's and 250F's. After a few laps on my YZ they come back with a wild look in there eyes like that had some enlightening moment. If the new four strokes are so much fun to ride why is it everybody wants to ride my bike?? Having grown up in the days of Hannah, Bailey, Ward, Johnson, O" Show...how can we let these fantastic machines go? Thank You Yamaha, Please keep making them....I have a feeling that they will make a rebound once the "average" rider gets sick and tired of the maintenance on their 4 stroke....I should know since I had an 06 Honda CRF250F and I returned it for the YZ...and I am much, much faster on the YZ especially with the 18 pound weight difference....
Dave B -Want !!  January 13, 2009 06:00 AM
I ride a done up 04 rmz250, pipe, hot cams, the works, and My mates stock 02 yz85 just about keeps up with it.. that wicked little thing throws the front wheel up every gear, His bike inspired me into Getting a 09 yz250 in mayish, Absolutely cant wait..I know i wont regret it!.
brian -YEAHHHHH BABYYYYYYY!!!!!!!!!!!!!!!!  January 2, 2009 10:25 PM
Just bought an 09 yz250..its like riding a lightning bolt with nitrous!!!!!I LOVE 2 strokes baby!4 strokers got nothin on me.
instigator73 -YZ250 vs. YZ250F power rating  December 31, 2008 07:40 AM
it's not only 45 hp for the YZ250, rather it produces peak 46.4 hp at 8500 rpm....see august 2008 MXA issue. in relation to this august 2008 issue, tracing back MXA's one of write-ups in 2005, the magazine said that the YZ250 makes around 46.8 hp at 8500 rpm and the engine can sustain that peak hp for long whereby at 9100 rpm it is still producing 45 hp, and loses only 5-hp (or a final 41.4 hp) at 9600 rpm before the rev-limiter hits. ok, going back to the august 2008 MXA issue, the 250F makes only a peak power of 36 hp but it needs to be at the screaming revs of 11,300 rpm to produce that. imagine how much engine wear there is compared to the 2T. torque-wise, it's also no competition against the 2T, where the YZ250 makes 30.6 ft-lb at 7600 rpm while the YZ250F only 20.1 ft-lb.
M.Fajardin -2009 YZ125  December 29, 2008 08:56 PM
I love two strokes! I fell in love with premix in junior high school, riding a 1987 YZ250. And now at 22yrs old I pilot a 2009 YZ125. And everyone on their big bore four strokes who have given my bike a fling have gone away saying, "the two strokes have two much power"! In the November edition of Motorcross Action, they showed the 2009 YZ250 makes 45 horsepower compared to the 2009 YZ250F which makes 36 horsepower (pg.45).
Bill Fischer -"All about fun"  December 18, 2008 06:10 AM
The main reason we buy these motorcycles is for the fun factor . I might be a little faster on the 450 4 stroke but I have much more fun on the 2 stroke . Yamaha will sell plenty of them since most of the competition has dropped out .
eric baker -a true winner  December 7, 2008 09:25 AM
the sound, the smell of a two stroke will always be a true love for me, i have always rode two strokes, i had a chance to ride an 2009 yz 450f. that bike is nice but turned it down to buy a 2009 yz125 this 125 rocks, even at 250lbs and 40 years old.

Austin O. -ktm and yamaha  November 22, 2008 07:22 PM
yeah. I hope Ktm and Yamaha are gonna keep the 2 strokes. I'm suppose to be buying an 05 YZ 125 tomorrow. 2 strokes are awesome. The smell, sound and lots more. They are powerful, quick, light and easy to maintain just like they said in the video about the 09 YZ 125 and 09 YZ 250. 4 stroke are a pain to fix, and the sound is lame i think. The really only things better about 4 strokes is they come out of turns better. But who really cares. There's nothing like a 2 stroke!!!!!! LONG LIVE 2 STROKES GO KTM and YAMAHA!!!!!!!!!!!!!
Don -2 Stroke  November 22, 2008 07:43 AM
I have a 2006 YZ125 and love it. I would not trade it for any other bike period. It's so light and has lots of power for a 125. I have ridden a KX250F once and will be honest and say it was a nice bike. The guy that let me ride it also made me kick start it and it took me about 6-7 kicks. It was cool to feel the difference in the power delivery but with the costs of buying a 4 stroke and maintaining one, I still prefer my 125. Besides, I love the crisp sound of a 2-stroke and that lightning hit when you twist the throttle not to mention the smell of premix. Yamaha's 2-strokes are the best too. My 125 is bone stock and it runs terrific. The only thing I have done to it is jetting. I hope Yamaha continues to make the 2-stroke because they do a wonderful job. Forever live the 2-stroke.
Shaariq -125s  November 14, 2008 10:59 PM
i love 2 strokes! i sold my 2008 honda CRF150R and bought a sighty used ktm 125sx, its mad fast, I also have a 2008 wr250 but you cant even ccompare it to the 125. 2 strokes all the way!
Shaariq -125  November 14, 2008 10:56 PM
i just sold my 2008 honda crf150R and bought a slightly used ktm 125sx, its mad, its so fast . My dad has a 2008 WR250, my ktm is faster and way more fun
Crf150Mx334 -2-strokes rule!!!!!!!!  November 13, 2008 06:32 PM
i ride a 2003 Honda crf 150f. I want to sell that and my pw 80 so i can get back into riding 2 strokes again.
dirtbikenut -two strokes = AWESOME!  November 10, 2008 02:05 PM
I'm a big 2 stroke fan also and recently I bought my son (who races Pro) a YZ250 with little to no time on it. He was racing CRF 450' and 250's but after watching him on the YZ250 I can honestly say that I think he is faster. Not to mention he says they are more FUN than his 450. Maybe I'll go and get myself a 125, always like them and road them better than any other bike!
Austin O. -2 stroke riding  November 7, 2008 05:38 PM
Ya. I love yz 125's. I'm getting one soon. I love 2 strokes. Not to be negative bout people that have 4 strokes but i really don't like 4 strokes. I want to keep these 2 strokes alive. I mean...If everybody likes them...then why stop making them. That's dumb! I mean..that smell and zinging noise the 2 strokes got... that's like the best parts bout them. Now y give that all up for these newer 4 stroke dirt bikes!4 strokes are cool..but 2 strokes just own them!!!!!!
mick grady -still need the 2 stroke  November 6, 2008 01:46 PM
I dont see how a 2stroke affects the environment enough to where they are discontinued. It may be the AMA. I dont know. For the average weekend racer/trail rider, the cheaper and easier to maintain 2 stroke just makes good sense. Let the factories totally trick thier thumpers without affecting the average consumer. What they race they have to sell to you and me. I dont need higher cost and headache to go out and have fun on the weekend. Please do not kill these fine machines.
zack vanummersen -keep 2 strokes alive  November 4, 2008 03:34 PM
your right theres nothin like a 2 stroke. it sickens me to find out that the beginning of motocross was with 2 strokes and now they are dying.i will do everything i can to keep 2 strokes out there, and fuck the tree hugger bastards trying to take the classics away.i will always ride 2 strokes and will never find myself buying a four stroke.
