Rider Profile

Best ForThis bike is best suited to beginner and younger riders, or smaller-statured adults, who are still building trail riding skills.
PurposeIt's a lightweight recreational off-road machine designed for trail play, dirt tracks, and learning to ride rather than any kind of speed or highway use.
Rider FitIts low seat height, low wet weight, and compact dimensions make it very approachable for short or lighter riders and easy to pick up if dropped.
CharacterExpect a forgiving, low-intimidation ride with a simple air-cooled single, carbureted engine and modest power delivery that rewards smooth throttle control over aggression.
Not Ideal ForThis is not the bike for taller or heavier adults, highway commuting, two-up touring, or anyone seeking real speed or long-distance comfort.

2024 Kawasaki KLX 140R Rider Ergonomics Assessment

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

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2024 Kawasaki KLX 140R, with a cramped knee angle of around 70 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.
