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

A really professional team, very approachable, helpful and enthusiastic. They want to make a difference by giving something back to the sport they’ve been involved with for so long. A great support to us when we started the TT with excellent advice and words of wisdom.

Finally I could try the DBS™ at the Mallorca Circuit and the result was FANTASTIC! The operation was very smooth and precise… I had no problem throughout the day! A couple of friends asked me to try my bike and they were surprised at how well it worked and asked me to install the DBS™ on their Kawasaki ZX10R 2012… Thank you so much for everything!

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!

Ian Wante

I’m driving a kart with a Vortex 125ccm RKZ engine and in the past used another shifting system but it wasn’t reliable and not powerful enough… I found the Pro-Shift PSU system with the stronger solenoid. The first test ride was great, a huge difference between old shifter and Pro-Shift! Shifts were 100% precise and super-fast, I had more than 300 rounds on our circuit without any problems!

Michael Steiner

Very knowledgeable and friendly staff. Professional and great aftercare, definitely would go back again!
