QS4 kit: Quickshifter Suzuki GSX-S 125 2017 – 2024
The QS4 is an advanced external Quickshifter kit that allows you to quickly shift up gears without using the clutch (clutchless upshift). The system works independently of the factory ECU, so it will also work well in motorcycles without standard quickshifter service or after modifications.
It is a solution created for sporty and dynamic driving – on the road and on the track.
