Does the Yamaha QT50 Yamahopper fit you?
The Yamaha QT50 Yamahopper (1979–1992) has a 695 mm seat height. As a rule of thumb, riders with an inseam around 70 cm — roughly 149 cm (4'11") tall — can plant both feet flat at a stop. Around 64 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 QT50 Yamahopper.
Riding position
As a moped motorcycle, the Yamaha QT50 Yamahopper puts you in an upright, neutral riding position. 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 QT50 Yamahopper best for?
The Yamaha QT50 Yamahopper is best suited to all-round road riding.
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.
