Rider Profile

Best ForThis bike rewards experienced off-road riders who understand two-stroke power delivery and clutch control, though its light weight makes it more forgiving than its race pedigree suggests.
PurposeBuilt specifically for competitive extreme enduro, hard enduro, and technical trail riding where minimal weight and maximum suspension travel matter most.
Rider FitThe extremely low dry weight and tall seat height demand active standing-riding technique and reasonable fitness, but the low mass makes it far easier to muscle through obstacles than a heavier machine.
CharacterA purpose-built, race-derived two-stroke enduro weapon that feels sharp, explosive, and utterly focused on technical terrain rather than comfort or refinement.
Not Ideal ForThis is not the right choice for commuting, highway touring, carrying a passenger, or anyone seeking plush comfort and low maintenance.

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

Feet:

At 963mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2025 KTM 300 EXC Six Days, 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.
