Rider Profile

Best ForSuitable for beginners and learner riders, including those on a moped or restricted-license permit, as this is a small-displacement 50cc two-stroke scooter.
PurposeDesigned purely for short-hop urban commuting and running errands around town rather than for speed or distance.
Rider FitVery light and low, with a compact frame that makes it easy for riders of almost any height or strength to handle and park.
CharacterA nimble, buzzy little two-stroke scooter that feels sprightly around town thanks to its light weight, chunky 10-inch tyres, and quick-turning nature.
Not Ideal ForNot for riders wanting highway speeds, long-distance touring, carrying a passenger comfortably, or any kind of off-road use.

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 2005 MBK Booster, 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.
