Rider Profile

Best ForThis small-capacity supermoto suits beginner to intermediate riders who want a light, forgiving bike to build confidence and skills on.
PurposeIt is designed for playful, nimble street riding and light urban commuting rather than outright speed or long-distance travel.
Rider FitIts low 114 kg weight and slim dimensions make it very easy to handle for shorter or lighter riders, though the 805 mm seat height requires reasonable inseam.
CharacterIt has a lively, flickable character typical of small supermoto machines, rewarding aggressive cornering lines over raw straight-line power.
Not Ideal ForIt is not suited to riders seeking highway touring comfort, high top speed, or carrying a passenger any real distance.

2010 Kawasaki KLX 125D Rider Ergonomics Assessment

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

Feet:

At 805mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 Kawasaki KLX 125D, with a moderate knee angle of around 115 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.
