Rider Profile

Best ForSuited to new or casual riders who just need simple, low-stakes transportation, note that the 267 kg dry weight figure listed seems inconsistent with a 49cc scooter and is likely a data error.
PurposeBuilt as a small-capacity automatic scooter for short urban hops rather than any kind of performance or long-distance riding.
Rider FitVery light and easy to handle at a stop or in traffic, with a low seat height and minimal physical effort required to ride.
CharacterA practical, no-drama commuter runabout with automatic transmission and modest power designed for convenience over excitement.
Not Ideal ForNot for riders wanting highway speed, long-distance touring, passenger comfort, or any off-road capability.

2009 MBK Booster X Rider Ergonomics Assessment

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

Feet:

At 750mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 MBK Booster X, 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.
