Abstract

A tilt-decoupled steering device of a motorbike includes a handlebar bridge which receives a handlebar, a fork bridge which receives a fork leg, and a decoupling element connecting the handlebar bridge to the fork bridge. The handlebar bridge (11) is rotatable about a steering axis and is secured about a tilt axis orthogonal to the steering axis. The fork bridge is rotatable about the steering axis and about the tilt axis. The decoupling element is elastic and is designed to transfer a steering movement in a steering direction about the steering axis from the handlebar bridge to the fork bridge, and to compensate for a tilting movement in a tilting direction about the tilt axis of the fork bridge relative to the handlebar bridge via elastic deformation.
