Rider Profile

Best For	Ideal for beginners or even younger riders, as this is a very low-powered, easy-to-manage 50cc scooter.
Purpose	Built purely for short urban hops, errands, and light commuting rather than any kind of performance riding.
Rider Fit	Extremely light and low seat height make it accessible and unintimidating for smaller or less experienced riders.
Character	A humble, economical city runabout with modest two-stroke buzz and no pretensions of speed or sportiness.
Not Ideal For	Not suitable for highway travel, touring, carrying a passenger comfortably, or anyone seeking real performance.

Units

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

Feet:

At 765mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2007 Yamaha Why, 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.
