Rider Profile

Best For	Best suited to intermediate or experienced riders who can manage a punchy, vibration-heavy big single with sharp, immediate responses.
Purpose	Built for supermoto thrills: tight, twisty roads, city dashes, and the occasional trackday rather than long-distance travel.
Rider Fit	The tall 860mm seat height and light 145kg dry weight demand decent leg reach but reward the rider with an easy-to-flick, low-effort chassis.
Character	A raw, rowdy, minimalist machine that thrives on aggressive throttle inputs and rewards an active, engaged riding style.
Not Ideal For	Not a good fit for riders seeking plush comfort, passenger-friendly ergonomics, or a relaxed long-haul touring companion.

Units

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

Feet:

At 860mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2001 KTM Duke II 640, with a relaxed knee angle of around 135 degrees and a forward-leaning 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.
