Rider Profile

Best ForThis is a small-wheel motocross machine built for younger or lighter riders progressing beyond an 65cc/80cc bike, not a beginner-friendly road bike.
PurposeDesigned purely for closed-course motocross racing and off-road training, not for street use or commuting.
Rider FitIts ultra-light weight and low-mid seat height make it manageable for smaller-statured or younger competitive riders rather than full-size adults.
CharacterA high-revving two-stroke racer that rewards aggressive, active riding with sharp, flickable handling on the track.
Not Ideal ForNot suitable for taller adults, road riding, touring, or anyone wanting a comfortable, low-maintenance daily ride.

2010 Kawasaki KX 85II 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 2010 Kawasaki KX 85II, with a cramped knee angle of around 70 degrees and a slightly forward riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
