Rider Profile

Best ForBest suited to intermediate-to-advanced off-road riders, as a small-bore two-stroke motocross machine demands active riding and precise clutch and throttle control to stay in its power band.
PurposeBuilt purely for motocross and cross-country racing on dirt tracks, not for street or commuting use.
Rider FitIts ultra-light dry weight and tall seat height favor smaller or lighter riders who can still comfortably manage the high seat and aggressive riding stance.
CharacterA high-strung, revvy two-stroke that rewards aggressive riding, quick gear changes, and an active body position with sharp, flickable handling.
Not Ideal ForNot suitable for riders wanting a comfortable, relaxed, road-going or touring motorcycle, or anyone seeking passenger capability or long-distance comfort.

2016 KTM 150 SX Rider Ergonomics Assessment

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

Feet:

At 960mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2016 KTM 150 SX, with a cramped knee angle of around 85 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.
