Rider Profile

Best ForThis is an ideal machine for beginners, younger riders, or those wanting a light, unintimidating supermoto-styled bike to build confidence on.
PurposeBuilt as a small-displacement supermoto-style commuter, it is best suited to short urban trips, playful backstreet riding, and light casual use rather than serious performance or distance work.
Rider FitIts very low weight and manageable seat height make it accessible and easy to handle for smaller or less physically strong riders.
CharacterIt has a nimble, flickable, toy-like personality that rewards playful low-speed riding over outright pace.
Not Ideal ForIt is not a good fit for highway touring, carrying a passenger regularly, or anyone seeking strong acceleration or high top speed.

2017 Kawasaki KLX125 Rider Ergonomics Assessment

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

Feet:

At 830mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2017 Kawasaki KLX125, with a relaxed knee angle of around 120 degrees and a slightly forward 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.
