Rider Profile

Best ForThis is a purebred competition enduro machine best suited to experienced off-road riders comfortable with a tall, aggressive, kick-start-only dirt bike.
PurposeBuilt for enduro racing and serious trail riding, not for road use or commuting.
Rider FitThe tall 925mm seat height, light 113.5kg dry weight, and physical demands of a full-size motocross-derived chassis require good rider fitness and reasonable leg length.
CharacterSharp, high-revving, and razor-focused, this bike rewards aggressive input with explosive agility and race-ready handling on rough terrain.
Not Ideal ForThis is not suited to riders wanting a comfortable daily commuter, a passenger-friendly bike, or a machine for long paved-road touring.

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

Feet:

At 925mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2005 KTM 450 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.
