Rider Profile

Best ForBest suited to intermediate or experienced riders who can manage a punchy big-single with a light, flickable chassis.
PurposeBuilt for aggressive backroad carving, supermoto-style street attacks, and tight, twisty riding rather than outright top-speed runs.
Rider FitLight dry weight and a tall-ish 865mm seat height suit riders of average-to-tall stature who want an upright, nimble stance.
CharacterRaw, torquey, and characterful, with the visceral thump of a big single and sharp, minimal-mass handling.
Not Ideal ForNot ideal for riders wanting plush long-distance comfort, wind protection, or a smooth two-up touring experience.

2010 KTM 690 Duke R Rider Ergonomics Assessment

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 2010 KTM 690 Duke R, with a relaxed knee angle of around 135 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
