Rider Profile

Best ForSuited to beginners or younger riders taking their first steps on a small automatic scooter.
PurposeDesigned purely for short urban hops and light commuting rather than any kind of performance riding.
Rider FitVery light and low-slung, so it is easy to handle for smaller or less experienced riders at a stop or in traffic.
CharacterA cheeky, nimble little two-stroke moped-scooter that favors quick darting through city streets over outright speed.
Not Ideal ForNot suitable for highway travel, long-distance touring, carrying a passenger comfortably, or anyone seeking real performance.

Rider Fit Visualizer

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

Feet:

At 768mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2012 MBK Booster 13-INCH Naked, with a moderate knee angle of around 95 degrees and a slightly forward 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.
