Rider Profile

Best ForThis is a beginner-level youth minibike intended for children learning to ride, not for experienced adults.
PurposeBuilt purely as a small-displacement kids' trail bike for supervised off-road practice and light dirt fun.
Rider FitIts tiny 685mm seat height and 58kg weight make it suitable only for small, lightweight young riders, not full-sized adults.
CharacterA simple, low-powered, air-cooled two-stroke with drum brakes and basic suspension, designed for gentle learning rather than performance.
Not Ideal ForThis bike is not for adult riders, highway use, touring, or anyone seeking speed or serious off-road capability.

2004 Suzuki JR 80 Rider Ergonomics Assessment

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

Feet:

At 685mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2004 Suzuki JR 80, 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.
