Rider Profile

Best For	Best suited to younger or smaller riders with intermediate motocross experience progressing from a minicycle toward full-size bikes.
Purpose	Built purely for closed-course motocross and off-road competition, not for street or general recreational riding.
Rider Fit	Its very low weight and compact seat height make it manageable for lighter or younger riders who would be overwhelmed by full-size motocross machines.
Character	A high-revving two-stroke minicycle that rewards aggressive, active riding with sharp, flickable handling on the track.
Not Ideal For	Not suitable for taller or heavier adults, commuting, road use, or anyone seeking comfort and long-distance capability.

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

Feet:

At 871mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with tip-toe one foot on the 2009 Kawasaki KX 100, with a cramped knee angle of around 75 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.
