quickshifter

Easy and safe quickshifter

directly integrated into the keihin ecu firmware

Overview:

The whole functionality relies on predefined gear ranges.
The software is comparing the live gear sensor against these gear ranges each crank revolution and decides whether to cut power or not.
Tight gear definitions allow very low engagement force to minimize gearbox and shift fork wear.
In order to enable smooth shifting with the clutch, the QS is inactive below the configured TPS threshold.

The software was entirely created from scratch
No parts were copied from the 2023+ KTM software!
This is to ensure the QS is working reliable and exactly as specified.

Compatibility:

In general this modification is possible to all 4 stroke KTM/Husqvarna and GasGas competition bikes using the gear position sensor

Subject to errors and changes


Installation procedure:

The quickshifter must be flashed on site as its neccessary to exactly configure gear ranges and your desired sensivity.
A remote flashing solution is not possible as of today
