This highly versatile patented system allows super fast clutchless up and downshifting, along with ultra high speed auto-blipped downshifts.

The Bump & Blip II™ system is an advanced quickshifter with a downshift blipping for seamless up and downshifting. Originally developed for the Isle of Man TT, the Digitally Programable Bump & Blip II™ features integrated ignition or fuel injection cuts plus a ramping restore facility, this allied with our DBS™ gives seamless clutchless up & downshifting.

Key features

Designed with passion, built for speed

Allows for super fast clutchless up and downshifting and provides "flat" upshifting with an integrated ignition ramping facility, along with ultra-high speed auto-blipped downshifts.

Absolutely no requirement for heavy compressors or vacuum modules to power the throttle blipper.

Triggers the "Bump & Blip" GCU to provide faster and more accurate gearshifts without the need for gearbox damaging load cells.

Allows for "flat" upshifting.

Gives smooth power restoration after "flat" upshifting, ideal for use in wet or slippery conditions.

Our customer feedback

Many thanks to Roy and Chris, amazing service as always! You are a fantastic team up there and always willing at short notice to help.

Adrian Lewis

For me as a disabled person, the PSU has helped me ride a motorcycle again. I have lost balance and nowadays prefer to ride a trike, I have used the PSU for about 15000 kilometres now and found it a great help! Now me and my lifelong partner enjoy the rides and make people and other riders turn their heads when we arrive at places, we are also members of the Wing Riders Golwing Club and take part in all rides and activities every month!

I have had a Pro-Shift system installed in my Escort MK2/ Tractive Gearbox now for a number of years and it has operated faultlessly throughout. The Pro-Shift team are without doubt the perfect example of what customer service and support should be. Highly recommended!
