What Is A Sachs MadAss?
The stock MadAss is a 125cc (or 50cc) German-engineered motorcycle with a unique minimalist design that mixes aggressive street fighter styling with classic and simple enduro-like qualities. In a nutshell, the MadAss is a motorcycle in its purest form.
Because of its size and 50cc heritage the current model MadAss is commonly labeled or mistaken for a scooter and while this isn't necessarily a horrible thing, it's not really fair to call the MadAss anything other than a motorcycle.
Weighing in at 220lbs and carrying a 124cc, 4-stroke, air-cooled engine, the stock MadAss can reach 55mph (give or take) and get up to 85 mpg on a single 1.22 gallon tank full.
Check out some of the reviews on the 125 Sachs MadAss.
In Canada, the MadAss goes by the name of Nitro and was imported by the Alliance Moteur Groupe (AMG) based in Brossard Quebec. The Nitro is a 2-speed automatic 50cc version of the same Sachs design.
The MadAss is also known as the Sachs Spider 125 in Japan
Don't Let The Size Fool You
Because the design and feel of the MadAss is at the heart of what motorcycling is all about, it's not hard to imagine that riding one is a blast. The solid, quality build and feel of the bike is a great confidence builder for new riders and an excuse for more seasoned riders to push their skills and have fun.
The MadAss is a sprinter and more at home with zipping around town in small trips rather then touring or long hauls but its legs were definitely proven by a 2,850 mile cross-country trip completed by Dr. MadAss and the guys over at the Pride of Cleveland Scooters.
The Cult Of MadAss
The MadAss is a definite attention-grabber even when it's sitting still. It's not at all uncommon for MadAss riders to get questions or comments at stop lights or parking lots. "What the hell is that thing?" "Do you build that thing yourself?" "What's it called? A Mad what?"
One thing is for sure: if you’re bitten by the "MadAss fever" it's safe to say that the only cure will be getting your hands on your very own.
It's a Global Thing
The Sachs MadAss is still the new bike on the block here in the States but it's already had a strong and dedicated showing in other parts of the world. MadAss owners are basically the same no matter where they are: passionate about this great bike.
