Rider Profile

Best ForIdeal for beginners or new riders, including those just stepping up from a bicycle or moped, thanks to its automatic transmission and tiny, unintimidating engine.
PurposeBuilt purely for short urban hops, running errands, and weaving through city traffic rather than any kind of performance riding.
Rider FitVery light and low, so it suits smaller or less physically strong riders and is easy to paddle around and park.
CharacterA cheerful, low-stakes commuter scooter that prioritizes simplicity, fuel efficiency, and nimble low-speed handling over outright speed or comfort.
Not Ideal ForNot suitable for highway travel, long-distance touring, carrying a passenger any real distance, or riders seeking any kind of thrill or power.

2010 Yamaha Bws Next Generation Rider Ergonomics Assessment

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

Feet:

At 803mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 Yamaha Bws Next Generation, 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.
