Rider Profile

Best ForThis is a serious offroad enduro machine best suited to riders with solid dirt-riding experience and confidence on technical terrain.
PurposeBuilt for competitive enduro and trail riding rather than road use, with a lightweight chassis and long-travel suspension designed to tackle rough, unpredictable ground.
Rider FitThe tall 925mm seat height, kick starter, and minimal dry weight demand decent rider fitness and confidence standing on the pegs, but the low mass makes it manageable for most body types once moving.
CharacterRaw, focused, and purpose-built, this bike rewards aggressive, skillful riding with exceptional agility and off-road capability rather than outright speed or refinement.
Not Ideal ForThis is not a good fit for new riders, commuters, or anyone seeking comfort, passenger capability, or sustained highway touring.

At 925mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2006 KTM 400 EXC Racing, with a cramped knee angle of around 80 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.
