1. An apparatus for controlling wheel slip in a motorcycle operated by a rider and having two or three wheels, comprising:
an anti-lock brake system, wherein the anti-lock brake system controls a braking force on a wheel of the motorcycle in relation to a slip ratio of the wheel. such that the anti-lock brake system reduces the braking force if the slip ratio exceeds a threshold:
an inertial measurement unit operably connected to the anti-lock brake system, wherein the inertial measurement unit outputs an inertial measurement signal to the anti-lock brake system, and the anti-lock brake system determines based at least in part on the inertial measurement signal whether there is a slide request from the rider; and,
a user interface device operably connected to the anti-lock brake system, the user interface device having an orientation. wherein the user interface device is a throttle of the motorcycle, a handlebar of the motorcycle, or a dedicated input device, and the orientation of the user interface device is manipulable by the rider within a range of motion, and, when it is determined by the anti-lock brake system that there is a slide request from the rider, the anti-lock brake system varies the threshold along a range of values based at least in part on the orientation of the user interface device.
