Rider Profile

Best ForThis bike is best suited to beginners, young riders, or smaller-statured adults taking their first steps into off-road riding.
PurposeIt's a lightweight trail and recreational off-road bike designed for casual dirt riding rather than speed or long-distance travel.
Rider FitIts low seat height and very light weight make it extremely approachable for smaller or less experienced riders.
CharacterIt's a friendly, forgiving, low-power trail companion that rewards playful, low-speed maneuvering over raw performance.
Not Ideal ForIt's not suitable for highway travel, touring, carrying a passenger, or riders seeking real speed or power.

2012 Kawasaki KLX 140 Rider Ergonomics Assessment

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

Feet:

At 780mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Kawasaki KLX 140, with a cramped knee angle of around 65 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.
