Touring riding position ergonomics: reach and angles

For a rider with the default 560 mm torso, 320 mm upper arm, 340 mm forearm, 450 mm thigh, 450 mm shin, 840 mm inseam (about 33 in), the touring riding position (upright, feet neutral: bar 470 mm forward and 340 mm above the hip, footpeg 260 mm forward and 490 mm below the hip, 750 mm seat height, 10 deg torso lean) models to a 76.1 deg knee angle and 80.9 deg elbow angle, both within geometric reach, and a +90 mm inseam-minus-seat gap. Computed with the Rider Triangle geometry model, method version 1.0.0, reviewed 2026-09-11.

What the touring position changes

The touring category (upright, feet neutral) moves the footpeg and handlebar coordinates relative to the hip, and changes the torso-lean assumption used to place the shoulder. Moving the footpeg further forward and the handlebar further forward and lower increases forward lean and can close down the elbow and knee angles for a given limb length; moving the seat lower shifts the inseam-minus-seat comparison without changing arm or leg geometry at all. These are broad editorial planning categories, not specifications for a manufacturer or model, and seat height and control layout vary widely within any one style. The computed angles above use this tool's own law-of-cosines solver against the default rider measurements; change the measurements in the simulator to model your own body.

A knee or elbow angle near 180 degrees is closer to straight; a smaller angle is more bent. An unreachable result means the straight-line distance between the joint endpoints is outside the sum or difference of the two limb segments for that body, not a measurement error. None of this establishes comfort, footing, clearance, or safe control; confirm the real motorcycle in person.
