Rider Profile

Best ForBest suited to intermediate to experienced off-road riders comfortable with a tall seat height and aggressive dirt geometry.
PurposeBuilt as a pure motocross-style off-road weapon for trail riding, cross-country racing, and technical terrain rather than street use.
Rider FitThe tall 900mm seat height and light 128kg wet weight favor taller or more athletic riders who can manage standing and shifting body weight over rough terrain.
CharacterA sharp, lightweight, high-revving dirt machine that rewards aggressive, active riding and quick directional changes over rocks, jumps, and loose surfaces.
Not Ideal ForNot suitable for riders wanting a comfortable road-going commuter, a passenger-friendly machine, or long-distance paved touring.

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

Feet:

At 960mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2025 Kawasaki KLX300R, with a cramped knee angle of around 85 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.
