Rider Profile

Best ForThis is a supermoto built for experienced riders who are already comfortable with a tall, light, single-cylinder machine that demands active input.
PurposeIt exists purely to carve up tight tarmac circuits and technical mixed-surface courses with razor-sharp direction changes, not to cover distance or haul gear.
Rider FitThe tall 898mm seat height, minimal weight at 109.3kg, and aggressive ergonomics reward a fit, confident rider who can move around the bike and manage a punchy single-cylinder power delivery.
CharacterExpect an explosive, visceral character with instant throttle response, flickable handling, and a chassis that thrives on aggressive lean angles and hard braking into corners.
Not Ideal ForThis bike is not for beginners, commuters, passengers, or anyone seeking comfort, wind protection, or long-distance touring capability.

Character map is an editorial estimate based on this bike's specifications, not a lab-tested measurement.

2006 KTM 450 SMR 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 2006 KTM 450 SMR, 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.
