Rider Profile

Best For	For young or lightweight racers progressing beyond minis; demands competent throttle and clutch control to manage its peaky two-stroke power.
Purpose	A dedicated youth motocross racer built for closed dirt circuits, jumps and berms — pure competition, not transport.
Rider Fit	Tiny and feather-light with a 750mm seat, 280mm ground clearance and long-travel WP suspension; sized for smaller riders on 17/14 wheels.
Character	Sharp, revvy and aggressive — a snappy liquid-cooled two-stroke that rewards commitment with explosive acceleration and razor agility.
Not Ideal For	Not for road use, commuting, touring or passengers; no lights, kick-start only, knobby tires and race-only intent make it street-illegal.

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

Feet:

At 845mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2025 KTM 85 SX 17-14, with a cramped knee angle of around 75 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.
