Terms

Bar risers

Blocks that lift the handlebar clamp. They raise only Bar height above hip. Handlebar risers guide

Baseline

A pinned setup to compare against. Try it in the Studio

Clip-ons

Handlebar halves clamped to the fork tubes, as in Sport. Sport riding position

Elbow angle

The inside angle between your upper arm and forearm. A straight arm is 180°. The tool does not compute wrist angle. Handlebar risers guide

Footpeg drop

The distance from your hip down to the footpeg, always positive. Footpeg position guide

Footpeg position

Where your feet rest, set by Footpeg forward of hip and Footpeg below hip. Footpeg position guide

Forward controls

Footpegs mounted ahead of the rider, as in Cruiser. Cruiser riding position

Handlebar rise and pullback

Rise is grip height above your hip. Pullback is how far the grips sit back toward you. Handlebar risers guide

Hip angle

The inside angle at the hip between your torso and thigh. A straight line is 180°. Footpeg position guide

Inseam

Your floor to crotch length, used only for the seat comparison. How to measure inseam

Inseam minus seat height

Inseam minus seat height, in millimeters. A positive gap does not mean both feet reach the ground flat. Seat height chart

Knee angle

The inside angle between your thigh and shin. A straight leg is 180°. Footpeg position guide

Lowering link

A part that lowers the seat by changing the rear suspension. The tool models it as a seat height change only. Seat height change guide

Measured from your hip

Grips and pegs are measured from your hip. The Seat down and Seat up what-ifs move the hip, so bars and pegs shift the other way. Measuring guide

Mid controls

Footpegs between standard and forward. The Touring example puts them 260 mm forward of the hip, between 180 mm for Standard and 500 mm for Cruiser. Touring riding position

Reach

The distance in a straight line, like shoulder to grip. The tool checks whether your limb can reach. How the model works

Rearsets

Footpegs mounted higher and further back than standard pegs. Footpeg position guide

Rider triangle

The shape made by your seat, handlebars and footpegs. How the model works

Seat height

The distance from the ground to the seat. The tool uses it only for inseam minus seat height, so it cannot say if your feet reach. Seat height chart

Torso lean

Your torso lean forward from vertical, in degrees. You enter it. Moving a control never changes it. How the model works

Unreachable

A result where the limb cannot span the distance. The tool says unreachable and never forces an angle. Methodology
