2010 Sachs MadAss 125 Review

Thursday, November 26, 2009
Brand new and full of contradiction for 2010 is the Sachs MadAss 125.
Is it motorcycle, moped or scooter? The Sachs MadAss 125.
Brand new and full of contradiction for 2010 is the Sachs MadAss 125. It’s compact and agile, yet stout and wildly aggressive looking, sort of like a pissed-off badger. Sachs went with a different animal analogy, a wild donkey. They also went with a different adjective, “mad” meaning furious or deranged. That, my friends, is how they came up with this fantastically eyebrow raising name.

Are you sure it’s a motorcycle? Well, you could call it the smallest naked street bike you’ve seen. You could almost hide it in a pack of bicycles chained to a bike rack. You could also call it the largest, manual shifting moped. The MadAss design draws a good bit of inspiration from an early relative, a 1939 moped called the Presto Saxonette. After 70 years of evolution we get a fresh new design that

has built quite a feverish following since its inception back in 2004. Here’s why:

Mad Genius
The genius of the MadAss lies in its simplicity. Weighing in at a sprightly 220 lbs, this bike would make even the most naked motorcycle blush. No fuel gage, no center stand, no storage compartments, racks or windshield, it’s “motorcycle” distilled to its purest form. Propelled by a 119.7cc, 4-stroke, 4-speed engine the MadAss is capable of reaching 56 mph right out of the box. A bone-stock MadAss is definitely no speed demon, but I found the riding performance to be fine for navigating the cityscape. I’ve been told that a handful of inexpensive bolt-on upgrades could push the upper limit to 75 mph without cracking the engine case.

Of course those sorts of shenanigans would reduce the 85-plus mpg fuel efficiency and possibly raise some environmental concerns. Exactly to what degree, you ask? We’ll continue conducting research on this as soon as our kit arrives. If you’re the tuning type, you’ll know that this particular engine design has been around for ages and lends itself to a plethora of bolt-on performance parts.

Brand new and full of contradiction for 2010 is the Sachs MadAss 125.
The Sachs MadAss 125 is powered by a 119.7cc 4-stroke Single which yields a remarkable 85-plus mpg efficiency.
So, back to the subject of fuel, Sachs continues the “Mad Genius” theme by hiding the 1.3 gallon fuel tank in the bike’s tubular, steel spine frame. When the tank is empty, you get the sputter warning (remember there’s no fuel gauge) which tells you to switch over to the one pint reserve, at which point you’ve got 20 miles to find a gas station. When you finally do pull over and unlock your aircraft styled gas cap to begin refueling you’ll stand a pretty good chance of hearing someone say “Wow! That thing is cool!” or “Whoa, what is that?” People know fun when they see it.

The MadAss features a lightweight, banana swingarm rear suspension, connecting to a preload adjustable mono shock, connecting to the bike’s frame all in a single, narrow plane. The front suspension is a standard hydraulic fork set up and one of few areas for improvement that I discovered. Hang on to that because I’ll summarize my improvement’s list in just a bit.

The 55w stacked projector beam headlights are straight out of the Streetfighter Bike Builder’s handbook. I prefer a wider field of view and found the low beam lighting to be a bit insufficient for my tastes. This gives me an excuse to begin customizing, I suppose.

The MadAss rides on a nice, sticky set of 16” tubeless tires mounted on alloy rims (yes, I agree, that a gnarly set of knobbies would be beautiful) and stops solidly thanks to an oversized set of front and rear hydraulic discs.

I had not done any long term testing for reliability, but my concerns there were quickly diminished after reading about a recent US coast-to-coast journey from a team calling themselves Dr.MadAss. A 3000-mile journey is pretty impressive and that’s nowhere near the 10,630 MadAss miles ridden by Australian motorcycle courier Nick Healey. It sounds like as long as you’re doing the maintenance, the MadAss will be doing the mileage.

Looking a gift horse in the mouth
Ok, it seems we’ve gushed a bit much in that first segment. Now let’s review the other side of this coin. What could be improved? The only storage on the MadAss is for gasoline. There are a couple of different luggage racks available currently and chances are pretty good that you’ll see lots of new accessories for the MadAss this spring, but you may want to get a good backpack if you need to haul a laptop.

Next on my list is the front suspension. The MadAss really dips during emergency stops and you’ll definitely want to stay away from the front brake if you find yourself having to brake around a turn. I recommend asking your dealer about swapping out the front fork oil for something a bit heavier; luckily a pretty inexpensive fix. If it’s still too soft you could consider upgrading the springs; also not very expensive.

Now on to ride comfort, which has been improved over the original MadAss with a bigger, better padded seat but it’s definitely not meant for touring. If you take a break every hour or so then rider fatigue shouldn’t be an issue.

While performance was satisfactory, I found the MadAss to be cold natured. There were times where I lost my riding group while choking the bike to warm it up. I’m told the issue here is that the carburetor needs a “fatter” pilot jet as well as some adjustments to the air / fuel mixture to fix the issue. I’ll be toying with these inexpensive options first to see if they make a difference.

Lastly, I did notice a couple of minor electrical glitches. The kickstand safety switch only killed the engine intermittently. Sometimes I’d put it down and the engine would stop, other times it just kept on putting. Also, after a few days of rapid up and down shifting, my neutral indicator light switch got stuck in the “on” position. These shouldn’t be issues at all, but they also sound like pretty quick fixes.
Sachs continues the Mad Genius theme by hiding the 1.3 gallon fuel tank in the bikes tubular  steel spine frame.
The MadAss 125 has is foibles, but makes for an intriguing small-displacement, fuel-efficient ride for those uninterested in the traditional scooter.

Let’s pin a tail on this donkey
Scooterists won’t like that there’s no storage or wind protection, motorcyclists won’t like that it gets more miles per gallon than miles per hour. But if you are new to the world of motorcycles or just need a light and nimble little campus bike, the MadAss fits the bill. The MadAss is also a great option for two-wheel commuters who had considered a scooter back in 2008, but just couldn’t imagine themselves riding one.

Overall I’m pleased with the MadAss. It’s simple to maintain, easy to tune, inexpensive to upgrade and looks great. I personally wouldn’t mind testing this bike as an automatic, not because I’m too lazy to shift, but as a benefit for riders coping with tendonitis or carpal tunnel syndrome.

Oh, and another advantage to being tiny is that the MadAss is forgiving. Studies show that over 40% of motorcycle accidents involve no other vehicle. The MadAss is less likely to “get away” from you and if it does, you just pick it up, dust it off and keep going.

The 2010 MadAss comes in both a 50 and a 125 with your choice of Bright Silver, Flat Black, Sun Yellow, or Graphite. Look for an MSRP of $2699 on the MadAss 125 and $1999 for the MadAss 50.

Hello All, This is not a reply to anyone, just my experience of the last eight months after I bought it brand new, what some may like to know about before buying one: I bought a Sahcs Madass because I though it was German Built, but the truth is that it is a Chinese made. The advertisement says German engineering, but the company is sold to China, the address of the company is also in China. Anyway: This Madass as time goes by falls apart. Also you have to service it quite frequently, the place I bought it from, wanted me to service it at 2/3 of the time that is said in the book, because they know you'll lose the warranty if you don't get it serviced by the official dealers as they pleased, because it is unique bike. Anyway after that time the bike will fall apart, they know it, so they just want to get your money before that. Rip you off. I've heard some noise in the engine and they told me that was the fault of the clutch cog wheel, so they replaced it, but the truth is that the noise was totally normal. My rear break kept crabbing on, they adjusted on the brake paddle, but did not noticed it was the fault of the rear brake Caliper, because the brake pads do not retract, only after if I turn the bike off for 5-10 mins, but after it grabs on again...Also the heat of the Sun makes ir worse too. My rear brake is broken now totally, keeps grabbing on, so I have to pay for fixing it myself. Due to the vibration of the motorbike all nuts and bolts come loose. The wire for the clutch got damaged due to normal use. The rain got to both systems of controls, such as the horn, ignition, etc. I had to take it apart, and spray some stuff on them. The nut and bolt holding the two parts of the bike together, where the rear wheel assembly connected came loose some time after service that means that anything can happen anytime to the Madass. My electric ignition works only sometimes now... The engine is leaking oil. If you ride it very fast it uses up all the fuel in a very short time. I would not recommend buying it. I loved the look, but now I realized I made a mistake. My mechanic I trust said straight away that this is a cheep Chinese motorbike, but I did not believe it, I thought it was German. I know it know, and the bike speak for itself. It falls apart. It has some normal vibration that shakes everything apart. Actually this is a normal shaking, I guess, and I cannot fully use the right handside mirror, because of that. Anyway, I do not recommend it, but anyway I hope you’ll have a better luck with it if you do...

I wish more companies would develop bikes with similar styles. Modern scooters look ugly as hell in my opinion.

Ah Mike! You had to finally start with the "Sissy bike, Unmanly drivel," Since no one's been too impressed with your anti scooter stuff! You have no idea! lol!
JDubya -Invisible Knight  February 9, 2010 07:36 AM
I see that it has a 4 speed, does it have a real clutch or is it auto clutch?
CP -But where's it made?  January 29, 2010 02:12 PM
The video mentioned "German-designed" as in "German engineering in da house- jah!" but I assume that means made in China or Taiwan. Is it better made than the pitbikes out of China?
toddol1971 -almost there, but not quite!  January 27, 2010 10:37 AM
Now all it needs is a 300cc motor cr80 forks and shock, knobby tires and real footpegs. I would buy it if it had that, or at least the motor, cause I can do the other stuff for relatively cheap.
aaron -just asking  January 3, 2010 06:46 AM
how much fuel can be filled with it?
michael milstead -Madass 125 in US  December 11, 2009 04:36 AM
The whole problem I have found with this motorcycle scooter is where to get them, they are just not around to be had, being a dealer I was able to get none not even a 50, plenty of customers looking but no bikes, the distribution is awful

Its Pimp!
LABiker -Hmmm  December 1, 2009 04:24 PM
Needs a G6 w/ CVT in it; it's a glorified scooter, and needs the displacement bump & CVT to be capable of short freeway hops.
shao -no tank to grip ?  November 30, 2009 04:21 PM
"there is no gas tank to grip with your knees. In my mind that is what makes this a scooter"

By that definition, a Sportster or a Gas Gas trail bike is not a motorcycle. On a Sportster, because of the air box, you cannot really grip the tank on one side. And many Gas Gas bikes have visually no tank...just some thoughts....
Steve781 -no tank to grip  November 30, 2009 09:40 AM
We looked at one of these this past weekend. My wife is looking for her first bike and she like the look of this. It helps that a major dealer for these is a short walk from our house. It is a great little bike in every respect but one, there is no gas tank to grip with your knees. In my mind that is what makes this a scooter. If you really want to learn to ride a bike then you need to know how to hang on with your knees to separate supporting your weight from your control inputs. If you want a really cool and very function scooter then do look at the madass. But know that it is a scooter. We pick up her 250 Ninja this week.
Mitch -Why is this under the scooter category?  November 30, 2009 09:36 AM
I wouldn't call this a scooter. You straddle it, it has manual shifting, and there's no storage. I would consider it a motorcycle, but for some reason you have it under your scooter category. In any case, this looks like it would be a fun play bike for the street. Oh, and milwaukee mike - give it up, dude. Your schtick has grown way too predictable and boring.
x2468 -klx110  November 27, 2009 05:34 PM
you could probably put a klx110 motor in it. since they look identical. But the KLX110 can be modded to hell by parts from BBR. big bore kits, cam, etc etc. I think you could get 22 horses out of a modified klx110 motor. The same as the flippen 500cc powered one without the weight.

Scooter Tuner - Bad Ass Bike November 26, 2009 02:02 PM
Cool bike. Just a little tuning and you could embarrass all the harley clowns by blowing them off the street. It wouldn't take much tuning to clean up on those overweight 65hp boat anchors. I tuned a 600CC Honda Silverwing scooter and that guy has a lot of fun picking on the harley clowns.
lol....Pirates arghhh!

Steve -Hey Frank  November 27, 2009 04:05 PM
Well, I'd say if you're doing 30 miles one way with time on the highway, I'd recommend something a bit bigger. A scooter may not look as vicious, but something like the Yamaha Majesty would eat that trip up AND give you lots of storage space.
Frank -can i has?  November 27, 2009 10:39 AM

also would this be ok for highway speed?
