Rider Profile

Best ForThis is a 50cc learner-legal moped-class machine, best suited to beginners, young riders, or those restricted to small-displacement license categories.
PurposeIt's designed as a sporty-styled city commuter for short urban trips rather than any kind of performance or long-distance machine.
Rider FitIts low seat height and lightweight sub-120kg build make it very manageable for smaller or less experienced riders.
CharacterThe X-Power mimics the look of a small sportbike with disc brakes and a six-speed gearbox, but its 50cc two-stroke engine only offers modest performance typical of the moped class.
Not Ideal ForThis bike is not for riders wanting real speed, highway touring capability, off-road use, or carrying a passenger any real distance.

2012 MBK X-Power Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 MBK X-Power, with a cramped knee angle of around 70 degrees and a forward-leaning riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
