About the HM GP Shifter

Offering the latest in technological advances to ensure the quickest and smoothest gear change possible.

The new HM GP Quickshifter has revolutionised the way in how quickshifters work, using a very complex algorithm called ‘The Kalman Algorithm’ to determine some key information during use. What this now does, amongst other features is give the GP Quickshifter the ability to beat the predetermined ‘kill time’ and release the power back on before this pre-determined time has elapsed in each gear which is also now fully programmable.


Launched on the last round of the MotoGP 2013, it was received with huge interest from from the biggest teams and names in the racing industry. So much so we were invited by Suter Racing Technology to attend the last closed test for Moto2/Moto3 of the year for the teams to test the GP Quickshifter.
