​Don’t let the relatively low price fool you into thinking that this is a low quality product - View our excellent feedback comments on ebay from many happy customers.

The Rapid-Shift has evolved over 2 decades into a simple, high quality, reliable and affordable Quickshifter. It has been regularly tried and tested in the toughest environments including moto-cross, supermoto, car, kart and road racing including WSB/BSB/Isle of Man TT.
Rapid-Shift requires no special tools or extra set-up/calibration devices and can easily be fitted in your garage/shed/street etc. It is not affected by water and sensor/kill time settings won't drift with temperature variations. 

The Rapid-Shift control box contains an 8 pin micro-controller with minimum components on a single sided printed circuit board encapsulated in a tough waterproof epoxy resin potting compound. The relays controlling the ignition or fuel injection coils are high spec, high current and unaffected by the level of vibration and G forces involved in motor-sports. 

We have had such a good reliability record for so many years now that we confidently offer a 30 DAY NO QUIBBLE FULL REFUND.

We aim to offer an excellent service at all times and value our reputation. If you do have any complaints or feedback which could improve this service then please contact us. This would help you by letting us rectify your problem and would also make our service/product even better.

If you’re not familiar with Quickshifters, they allow faster, full throttle, clutch-less gear changes resulting in increased acceleration, better corner stability and reduced lap times.I've never checked but I should imagine you would rarely see a race bike at National or International level without one. This fact alone speaks volumes as these professional teamswouldn't add anything which didn't give measurable benefits.

How It Works:- The control box is constantly watching the sensor (every 1000th of a second) to detect the position or pressure of the gear lever when the gears are about to be separated (gearbox selector drum starts turning). The control box then cuts either the ignition or fuel injection and starts the kill time. This can be adjusted from 55 to 85 milliseconds (1000th of a second = 1 millisecond). When the kill time is over and the next gear selected, the engine power is restored and the control box carries on monitoring the sensor making sure the lever has returned before allowing the next shift.
