Rider Profile

Best ForThis is an ideal first powered two-wheeler, suited to complete beginners and commuters with minimal riding experience.
PurposeBuilt purely for short urban hops, errands, and light commuting rather than any kind of performance or distance riding.
Rider FitIts low seat height, light 83kg weight, and automatic transmission make it extremely easy and unintimidating for riders of nearly any size or strength.
CharacterA cheerful, no-fuss small-wheel scooter that prioritizes simplicity, low running costs, and effortless maneuverability over speed or excitement.
Not Ideal ForThis is not the right machine for highway travel, long-distance touring, carrying a passenger comfortably, or anyone seeking real performance.

2014 Yamaha Bws 12 Inch 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 2014 Yamaha Bws 12 Inch, 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.
