Rider Profile

Best ForThis is a 50cc moped-class scooter suited to complete beginners and learner riders, not experienced motorcyclists seeking performance.
PurposeIt's designed purely as a lightweight, nimble runabout for short urban trips, commuting, and errands rather than any kind of performance riding.
Rider FitIts low weight and low seat height make it very easy to handle, manageable for smaller or less physically strong riders, and simple to paddle and park.
CharacterThe AeroxR has a sporty, aggressive scooter styling that gives it a fun, youthful character despite its very modest 50cc performance.
Not Ideal ForIt is not suitable for highway travel, long-distance touring, carrying a passenger comfortably, or anyone wanting real speed or power.

2009 Yamaha AeroxR Rider Ergonomics Assessment

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

Feet:

At 828mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2009 Yamaha AeroxR, with a moderate knee angle of around 105 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.
