Does the Yamaha XT660X fit you?
The Yamaha XT660X (2014–2014) has a 865 mm seat height. As a rule of thumb, riders with an inseam around 87 cm — roughly 185 cm (6'1") tall — can plant both feet flat at a stop. Around 81 cm inseam you'll be on the balls of your feet, and shorter riders will tiptoe. Enter your own height and inseam in the simulator above to see exactly how you reach the ground on the Yamaha XT660X.
Riding position
As a supermoto motorcycle, the Yamaha XT660X puts you in a mild forward lean. The simulator scores the exact knee, hip, and elbow angles for your body so you can see how relaxed or aggressive the reach to the bars and pegs will feel.
What is the Yamaha XT660X best for?
The Yamaha XT660X is best suited to agile urban and back-road riding from a tall, upright perch.
Braking & stopping distance
At 186 kg wet plus a rider, a hard stop from 100 km/h on dry tarmac takes roughly 39 m (about 1.00 g). Stopping distance is grip-limited, so it is set far more by tyres and road surface than by the bike or rider weight.
Fit figures are rules of thumb (flat-foot inseam ≈ seat height); the simulator gives your exact reach and joint angles. Braking is an estimate from wet weight and wheelbase on a dry road.
