Quick Shifter Sensor Yamaha KXF 450

The Quick-Shifter sensor detects the shifting process and interrupts the ignition (in conjunction with the GPX-H8) or the injection (in conjunction with the GP1 EVO tuning box) for milliseconds. Thus, the upshift under full load and full throttle is also possible without clutch and without throttle removal. The result is better acceleration! 

GPXH8 ignition box required or
