Rider Profile

Best For	Best suited to riders with at least some prior experience, since the tall seat, supermoto-tuned chassis, and sharp handling reward confident, active riding.
Purpose	Built as a road-focused supermoto, this bike is meant for flicking through tight city streets and attacking twisty backroads rather than long-distance cruising or serious off-road work.
Rider Fit	The 865mm seat height and light 186kg weight favor taller or more athletic riders who can comfortably manage the bike at a stop and enjoy standing-up, aggressive body positioning.
Character	It suits a playful, corner-hungry rider who values sharp steering, sporty street handling, and a punchy single-cylinder engine over outright top speed or plush comfort.
Not Ideal For	It is not a good match for riders seeking a relaxed touring companion, heavy passenger carrying capability, or a highly capable off-road adventure machine.

Units

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

Feet:

At 865mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2011 Yamaha XT660X, 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.
