Rider Profile

Best ForThis bike suits experienced riders who are comfortable with a powerful, top-heavy V-twin that responds sharply to throttle and brake input.
PurposeBuilt as a supermoto, it excels at aggressive, flickable cornering on tight twisty roads and occasional track days rather than long-distance cruising.
Rider FitThe tall 875mm seat height and firm, upright riding position demand good leg length and core strength for hustling the bike through corners.
CharacterIt has a punchy, torquey V2 engine character paired with razor-sharp steering geometry, making it feel eager, playful, and slightly wild at low speed.
Not Ideal ForIt is not a good fit for riders wanting a plush, wind-protected long-haul tourer or a machine suited to serious off-road trail riding.

2008 KTM 990 Supermoto Rider Ergonomics Assessment

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

Feet:

At 870mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2008 KTM 990 Supermoto, with a relaxed knee angle of around 140 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.
