Rider Profile

Best ForBest for experienced riders; its peaky, high-revving nature and aggressive ergonomics punish beginners. Ideal for those with track or sport-riding background.
PurposeA dedicated supersport built for carving canyons and lapping racetracks. It rewards precision and high revs over relaxed cruising or hauling gear.
Rider FitAggressive committed riding position: tall 850mm seat, low clip-on bars, high rearsets. Compact and light at 190kg, but hard on wrists at low speed.
CharacterA razor-sharp, screaming inline-four that lives above 10,000 rpm. Flickable, precise and thrilling on a smooth road or track, demanding but rewarding.
Not Ideal ForNot for beginners, commuters seeking comfort, two-up touring, or anyone wanting easy low-rev torque or long-distance ease.

2003 Yamaha YZF-R6 Rider Ergonomics Assessment

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

Feet:

At 820mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2003 Yamaha YZF-R6, with a cramped knee angle of around 70 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.
