Quickshifter

A quickshifter or quick shifter is a device that eliminates the need to use the clutch or throttle when shifting gears on a manual transmission.

Mechanical, linear, sensors typically close a micro switch at a factory preset force level in one particular direction only.

In comparison with the mechanical type these relevant features ensure a more accurate, error free, shift detection for after-market applications, depending on rider preference, use case and, set correctly, reduce wear on the transmission gear selection system.

The load on the transmission is generally reduced (or "unloaded") by cutting off the ignition and/or fuel supply of the engine, or by disengaging the clutch.

To avoid a hard shock reaction on the chain drive, stand-alone modules can activate the cut cylinders in a staggered, controlled manner.
