Pro-Shift Digital Closed Loop Bump & Blip System


Probably the fastest manual Flatshifter & Downshift-Blipper on earth, providing under 25 mS (millisecond) up shifts and super fast clutchless auto-blipped downshifts.

This unique patent applied for closed loop Flatshifter system USES NO LOAD CELLS.

Providing "flat" upshifting with integrated seamless ignition control, the system also provides ultra high speed auto-blipped downshifts.


Utilising linear potentiometer feedback to sense gear shift position. This double IOM TT winning closed loop Flatshifter System takes individual gear position readings every 1/1000th of an inch. 

Remote digital readout screen makes programming easy.

Integral closed loop controlled self adjusting ignition cuts allow "flat" upshifting in all conditions.

Stand alone  ignition or fuel cuts provided allow "flat" shifts with any ECU.

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

Optional external ignition or fuel control signal allows the ignition "cuts" or retardation to be operated by a variety of high spec ECU's.

Electronic Downshift Blippers are "on time" adjustable, available with either telescopic or remote cable operation to suit all applications. These unique ultra fast high powered solenoid driven devices are specifically designed to "blip" the throttle to allow seamless clutchless downshifts. Unlike some air or vacuum devices these units will not run out of power during multiple downshifts.

DBW Blippers now also available.

Easily adjustable for "tuning" the system to your personal style of driving.

No requirement for compressors or vacuum modules.

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!

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.

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.
