Rider Profile

Best ForThis is a moped-class 50cc scooter suited to new or learner riders, typically restricted to those with a basic license or moped permit.
PurposeBuilt purely for short urban hops, errands, and commuting rather than any kind of performance or long-distance riding.
Rider FitVery light weight and a low, accessible seat height make it easy to handle for smaller or less experienced riders.
CharacterA nimble, playful little runabout with sporty naked styling that punches above its weight in city agility despite minimal power.
Not Ideal ForNot suitable for highway travel, touring, carrying a passenger any real distance, or anyone seeking genuine speed or performance.

2014 Yamaha Aerox R Naked 50 Rider Ergonomics Assessment

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

Feet:

At 815mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2014 Yamaha Aerox R Naked 50, with a moderate knee angle of around 100 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.
