Rider Profile

Best ForThis is a small kids' off-road trail bike, not a scooter despite the listed category, and is intended for young beginner riders learning basic motorcycle control under supervision.
PurposeBuilt purely as an entry-level youth trail bike for supervised riding on dirt trails, yards, and easy off-road terrain, not for adult transportation or road use.
Rider FitIts extremely low seat height, light 61 kg weight, and low-power semi-automatic drivetrain make it accessible to small children and lightweight new riders with minimal strength or experience.
CharacterA simple, forgiving, low-power two-stroke trainer bike with a semi-automatic clutch designed to build confidence rather than deliver performance.
Not Ideal ForIt is not suitable for adult riders, highway or city road use, touring, passengers, or anyone seeking real speed or power.

2009 Yamaha PW80 Rider Ergonomics Assessment

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

Feet:

At 635mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Yamaha PW80, with a cramped knee angle of around 55 degrees and an upright 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.
