Rider Profile

Best For	Suits riders with at least some prior experience, as the tall seat and supermoto-tuned chassis reward confidence rather than pure beginners.
Purpose	Built as a road-going supermoto for sharp cornering, urban attacks, and twisty backroad fun rather than long-distance cruising or serious off-roading.
Rider Fit	The 865mm seat height and 189kg weight mean shorter riders may find it a stretch, though the slim single-cylinder chassis keeps it manageable at a standstill.
Character	A punchy, torquey single-cylinder engine paired with sharp street tyres and supermoto ergonomics gives it a playful, flickable, and engaging personality.
Not Ideal For	Not ideal for riders wanting serious off-road capability, high-speed touring comfort, or a two-up long-distance mount.

Units

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

Feet:

At 865mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with tip-toe one foot on the 2010 Yamaha XT 660X, 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.
