Pro-Shift Bump & Blip Shifter II TM

Available for Sequential gearboxes                                                                                                                                                                                                                                                                                                         Specifically designed to provide super fast clutchless up & downshifting this unique system provides clutchless "flat" upshifting with intergrated ignition or fuel injection ramping restore facility allied with ultra-high speed Auto-Blipped downshifts.


Uniquely utilising a two way Hall Effect Sensor to trigger the "Bump & Blip II'" GCU (Gearshift Control Unit) this revolutionary operation method provides far faster more accurate gearshifts than other conventional methods without the need for load cells.

Important note, The Bump & Blip II's two way Hall Effect Sensor has two 6mm male threaded ends and requires fitting "in line" to the gearbox's operating rod or gearlinkage so the gearshifting forces act on the cell to effect upshift cuts and downshift blips, if your vehicle does not have this then Pro-Shift can provide alternative solutions.

Integral timer controlled fully adjustable ignition or fuel injection cutting allowing "flat" upshifting.

Timer controlled ignition or fuel injection ramping facility giving smooth power restoration after "flat" upshifting, ideal for use in wet or slippery conditions.

Fully adjustable timer controlled DBS ™ (Downshift Blipping System) "on times" providing ultimate control over clutchless downshifts.

Patent Pending Hybrid Remote cable Downshift-Blipper for Car Throttle Bodies including idle screw replacement ferrule, this works in a pushing motion making the installation very quick and simple, This ultra fast acting downshift blipper utilizing a specifically designed lightweight solenoid will provide reliable high speed clutchless dowsnshifts with a typical "on time" of around 50mS allowing precise multiple downshifts.

Telescopic Throttle Blipper this works in a pulling motion and is suited to throttles where a pushing blipper is not.

DBS ™ (Downshift Blipper System) modules available for Drive By Wire (DBW) throttles

After 3 seasons of use the gearbox internally looks like new and needs no revision at all. This shows how good the Pro-Shift system has worked. All I can say is thank you very much to all at Pro-Shift for such a good package, I can fully recommend it to anyone looking for a similar system!

Thanks so much Pro-Shift! The system is amazing on the road, can't wait to get it on the track. Well worth the money, the only thing that beats your product is your customer service. Couldn't recommend enough!!!

Really happy with the system. It's just completed the bike, it's made it so stable on heavy braking and down shift!! The lap times are the proof I needed! Transformed the bike so a big thank you to all at Pro-Shift.

Everything installed and if I had to give a rank from 0 to 10 for it I would give 12.

Your shifter works exceptionally well. The ability to shift through corners allows for fast corner shifting without having to change riding geometry and is a great benefit. I won my first race of the weekend virtually without practice. Very pleased.
