Rider Profile

Best For	Best for intermediate to experienced riders who enjoy a lively single-cylinder character; the tall seat and punchy delivery reward confident, active riding.
Purpose	A sharp, minimalist streetfighter built for backroad carving, spirited city blasts and quick B-road runs rather than long-haul mileage.
Rider Fit	Very light (148kg dry) with a lofty 865mm seat and upright, roomy naked-bike stance; slim, flickable and easy to muscle for taller riders.
Character	A single-cylinder hooligan: torquey thumper punch, razor-sharp handling and no-nonsense KTM attitude packed into a featherweight trellis chassis.
Not Ideal For	Not for tourers, two-up cruisers, or riders wanting all-day comfort, a low seat, or smooth long-distance highway manners.

Units

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

Feet:

At 865mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2011 KTM 690 Duke, 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.
