Rider Profile

Best ForThis is a beginner-friendly moped-class scooter suited to new riders or those with only a basic license, note the dry weight figure listed (267 kg) appears inconsistent with a 50cc scooter and is likely a data error.
PurposeBuilt purely for short-hop urban commuting and running errands around town, not for speed or distance.
Rider FitVery light and low seat height make it accessible to riders of almost any size or strength, with minimal physical demands.
CharacterA cheeky, playful little naked scooter with sporty 10-inch wheels, meant for zipping through city streets with a bit of attitude.
Not Ideal ForNot suitable for highway riding, long trips, carrying a passenger comfortably, or anyone seeking real performance.

2009 MBK Booster Naked Rider Ergonomics Assessment

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

Feet:

At 768mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 MBK Booster 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.
