Rider Profile

Best ForThis is a serious offroad enduro machine best suited to intermediate-to-advanced riders comfortable with a light, punchy two-stroke.
PurposeBuilt purely for technical enduro trails, woods riding, and competitive offroad use rather than road or highway travel.
Rider FitThe tall 963 mm seat height, minimal seat padding, and firm long-travel suspension demand good rider fitness, leg length, and standing-riding stamina.
CharacterA featherweight, high-revving two-stroke enduro bike that rewards aggressive, active riding with sharp handling and explosive low-weight agility over obstacles.
Not Ideal ForNot suitable for riders wanting a comfortable commuter, a passenger-friendly bike, or a machine for sustained highway touring.

Feet:

At 985mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2010 KTM 250 EXC, with a moderate knee angle of around 90 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.
