Abstract

A tilt-decoupled steering device of a motorbike includes a handlebar bridge for receiving a motorbike handlebar, a fork bridge for receiving a fork leg, and at least one decoupling device connecting the handlebar bridge to the fork bridge. The handlebar bridge is mounted such that it can rotate about a steering axis and is secured about a tilt axis orthogonal to the steering axis, and the fork bridge is mounted such that it can rotate about the steering axis and about the tilt axis. The decoupling device transfers a steering movement and a steering torque in a steering direction about the steering axis between the handlebar bridge and the fork bridge, and compensates for a tilting movement in a tilting direction about the tilt axis of the fork bridge relative to the handlebar bridge.
