Rider Profile

Best For	This bike is best suited to younger or smaller-statured riders, or beginners, moving up from a mini or 85cc machine and building motocross skill.
Purpose	Purpose-built for closed-course motocross and off-road track riding rather than any form of street use.
Rider Fit	Its very light weight and low-mid seat height make it manageable for smaller or lighter riders, though the two-stroke power delivery still requires active, energetic riding.
Character	A nimble, high-revving two-stroke motocrosser that rewards aggressive throttle and clutch work with sharp, flickable handling on rough terrain.
Not Ideal For	Not suitable for highway travel, commuting, carrying a passenger, or riders seeking comfort and long-distance touring capability.

Feet:

At 871mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2021 Kawasaki KX100, 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.
