Rider Profile

Best ForSuitable for beginners and casual riders, including those newer to two wheels thanks to the automatic transmission and low seat height.
PurposeBuilt primarily as a nimble urban commuter for short hops, errands, and weaving through city traffic rather than performance riding.
Rider FitVery manageable for riders of most sizes and strengths, with a light weight and low seat height that make it easy to handle at stops and in tight spaces.
CharacterA practical, easygoing little scooter that prioritizes convenience and maneuverability over outright speed or excitement.
Not Ideal ForNot a good fit for highway touring, long-distance travel, off-road use, or riders seeking strong acceleration and high top speed.

2013 Yamaha Bws 125 Rider Ergonomics Assessment

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

Feet:

At 780mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2013 Yamaha Bws 125, 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.
