Does the Yamaha DT125R fit you?
The Yamaha DT125R (1988–1989) lists a 840 mm seat height. In this simplified seat-height model, an inseam around 84 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 DT125R's dual-sport category suggests a tall, upright seated 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 dual-sport category is commonly associated with on/off-road versatility and lighter trail use, usually with a tall seat. 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.
