Does the Yamaha QT50 Yamahopper fit you?
The Yamaha QT50 Yamahopper (1979–1992) lists a 695 mm seat height. In this simplified seat-height model, an inseam around 70 cm is a rough ground-reach reference, not a guarantee of flat-footing. Seat width, suspension sag, boots, mobility, load, and individual proportions can materially change foot contact. Enter your measurements above to compare the modeled reach, then confirm it on the motorcycle.
Riding position
The Yamaha QT50 Yamahopper's moped category suggests a compact, upright low-speed position as a modeled starting point. The simulator estimates knee, hip, and elbow angles from the available geometry and your measurements so you can compare the reach to the bars and pegs.
Typical category use
The moped category is commonly associated with short urban trips and low-speed everyday transport with minimal weight and complexity. Rider Height does not assess handling, performance, or whether this motorcycle is suitable for a particular rider.
Fit figures are planning estimates from the current geometry and simplified model assumptions. They are not safety, compatibility, or purchase advice; confirm fit on the actual motorcycle.
