Rider Profile

Best ForThis is a small-wheel youth motocross machine best suited to younger, developing riders transitioning from an 65cc/80cc up toward full-size bikes, not adult riders.
PurposeBuilt purely for closed-course motocross racing and off-road training, not for street use or general recreation.
Rider FitIts light 69 kg weight and 841 mm seat height make it manageable for smaller, lighter riders, typically pre-teens to early teens.
CharacterA high-revving two-stroke racer that rewards aggressive riding, clutch work, and precise line choice on the track.
Not Ideal ForNot suitable for adult riders, highway or commuting use, passengers, or anyone wanting comfort and touring capability.

2015 Kawasaki KX 85 Rider Ergonomics Assessment

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

Feet:

At 841mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2015 Kawasaki KX 85, with a cramped knee angle of around 70 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.
