Rider Profile

Best ForBest suited to newer-to-intermediate riders who want a light, forgiving supermoto to sharpen their cornering skills.
PurposeDesigned for flickable street-based fun, tight backroad carving, and casual urban riding rather than outright speed or distance.
Rider FitThe tall seat height and lightweight chassis favor riders of average-to-taller stature who can comfortably manage a supermoto's stand-up ergonomics.
CharacterA playful, nimble small-bore supermoto that rewards aggressive lean angles and quick direction changes over long highway stints.
Not Ideal ForNot a good fit for riders seeking high top speed, long-distance touring comfort, or serious off-road capability.

2025 Kawasaki KLX300 SM Rider Ergonomics Assessment

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

Feet:

At 861mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2025 Kawasaki KLX300 SM, with a relaxed knee angle of around 135 degrees and a forward-leaning 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.
