Rider Profile

Best ForThis is a demanding, kick-start-only big-bore enduro best suited to experienced off-road riders comfortable with a tall, lightweight, high-compression single.
PurposeBuilt for serious enduro and cross-country off-road riding rather than road use, blending motocross-derived performance with just enough road-legal equipment to link trails.
Rider FitThe tall 940mm seat height, firm suspension, and kick-start big single demand a fit, confident rider with good off-road technique and leg strength.
CharacterRaw, torquey, and purpose-built, this machine rewards aggressive, skilled riding with sharp handling and strong off-road capability rather than comfort or refinement.
Not Ideal ForThis is not a good fit for beginners, shorter riders, or anyone wanting a comfortable, low-maintenance road or touring bike.

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

Feet:

At 980mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2005 KTM 625 SXC, 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.
