Rider Profile

Best ForSuits riders with at least some prior experience, as the tall seat height and single-cylinder torque delivery reward confident handling.
PurposeDesigned as a supermoto-styled machine for punchy, playful riding on twisty tarmac and light urban duty rather than outright speed or long-distance touring.
Rider FitThe 875mm seat height and 177kg dry weight demand reasonably long legs and moderate strength for stop-and-go maneuvering.
CharacterA lively, single-cylinder torque-driven bike that feels agile, upright, and eager to flick through corners with minimal fuss.
Not Ideal ForNot ideal for riders seeking high-speed highway cruising, plush two-up touring comfort, or serious off-road capability.

2007 Yamaha XT 660 X 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 2007 Yamaha XT 660 X, 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.
