Rider Profile

Best ForThis bike rewards confident, experienced riders who understand how to manage a light, powerful, and razor-sharp chassis.
PurposeBuilt for attacking twisty roads, supermoto track days, and turning ordinary streets into a playground for aggressive cornering.
Rider FitThe tall 880mm seat height and firm, minimal seating position demand good leg length and reasonable fitness for extended riding.
CharacterA raw, high-strung big single that feels like a dirt bike wearing street tires, delivering visceral thrills and instant responsiveness.
Not Ideal ForThis is not the right bike for riders seeking long-distance comfort, passenger accommodation, or a relaxed, low-maintenance ride.

2008 KTM 690 Supermoto R Rider Ergonomics Assessment

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

Feet:

At 875mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2008 KTM 690 Supermoto R, 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.
