Rider Profile

Best ForThis is a competition minicycle built for young, developing riders who already have solid off-road fundamentals, not a beginner's first bike.
PurposeIt exists purely for motocross racing and skill progression, bridging the gap between smaller youth bikes and full-size 125cc machines.
Rider FitIts low 845mm seat height and light, compact chassis are tailored specifically to a young rider's smaller stature and developing strength, not adult use.
CharacterThe high-revving 2-stroke engine delivers sharp, explosive power that rewards aggressive clutch work and precise throttle control on the track.
Not Ideal ForIt is entirely unsuitable for adult riders, road use, touring, or anyone seeking a comfortable, forgiving, everyday motorcycle.

Character map is an editorial estimate based on this bike's specifications, not a lab-tested measurement.

Rider Fit Visualizer

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

Feet:

At 750mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2013 KTM 85 SX 17-14, 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.
