aRacer QSS V2 Standalone Quick Shifter (Single Cylinder)

The QSS V2 (QS Sport V2) is a standalone quick shifter for single-cylinder bikes: clutchless, full-throttle upshifts without replacing the ECU. It cuts the ignition for the shift on its own, so it suits a Grom, Z125, CRF or similar single running the stock ECU, or a bike where you only want a quick-shift upgrade.

Running an aRacer Super X / Super XX ECU? The QSR V2 integrates with the ECU and is the better kit.

Features

• Standalone quick shifter for one-cylinder applications
• Clutchless upshifts once installed and configured
• Faster, more consistent shifts for race and track use
• Suits motorcycle, mini-moto and scooter builds where supported
