UPDATE: The Sachs MadAss 125cc German-Engineered Motorcycle

UPDATE: Based on the original groundbreaking Sachs Madass 50, only 150% madder, the 125cc version is like no other motorcycle.

Designed and manufactured by Sachs of Germany, who celebrate their 120th anniversary this year, the Sachs Madass 125 shares the minimalist philosophy of its smaller sibling.

Engine: 125cc / 4-stroke / Single cylinder

Fuel is carried in the frame, so a bulky fuel tank is not required and the twin seat sits on a single tube running from the bike’s spine, so no rear sub frame is required.  The result is an incredibly light machine, weighing just 95kg, which is substantially lighter than similar capacity motorcycles*.

As you would expect from a German company that has been in business since the 19th century, there is no compromise when it comes to quality components.  Reliable stopping power is delivered by a 260mm front hydraulic disc brake, backed up by a 215mm hydraulic unit at the rear.

The beefy rear mono-shock absorber has hydraulic damping and adjustable pre-load, so suspension can be tailored to suit the rider.  Twin stacked headlights provide plenty of illumination as well as giving the front end an aggressive ‘streetfghter’ appearance.  Power is provided by a reliable 4-stroke engine, which can be started at the push of a button.   A cool oval silencer, fitted with a catalytic converter, takes care of emissions.

Sachs are confident that the Madass 125 will be a hit with riders who understand that some bikes take themselves too seriously. The Madass 125 can be ridden by anyone aged 17 or over.

The Sachs 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.

Because the design and feel of the Sachs 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 Sachs 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 Sachs MadAss is a definite attention-grabber even when it’s sitting still. It’s not at all uncommon for Sachs 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.

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.
