Rider Profile

Best ForBest suited to intermediate and experienced riders who can manage strong V-twin torque and a sharp, aggressive chassis.
PurposeBuilt primarily as a street-oriented naked brawler for fast backroad blasts and spirited cornering rather than long-distance cruising.
Rider FitA light, compact naked bike with a fairly tall 850mm seat that suits riders of average to above-average height and confident low-speed handling.
CharacterAggressive, torquey, and razor-sharp, with a raw big-twin character that rewards an active, engaged riding style.
Not Ideal ForNot ideal for riders seeking plush touring comfort, wind protection, or any serious off-road capability.

2008 KTM 990 Super Duke Rider Ergonomics Assessment

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

Feet:

At 855mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2008 KTM 990 Super 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.
