Pro-Shift Digital Closed Loop Bump & Blip™ System

Double IOM TT Winning Closed Loop Bump & Blip™

The Pro-Shift Digital Closed Loop Bump & Blip™ for Supercars with Sequential Transmissions

Originally designed for the Isle of Man TT to provide Super-Fast Clutchless Up & Downshifts.. The patent pending Digital Closed Loop Bump & Blip™ System combines Flat Upshifts with our highly effective DBS™ (Downshift Blipping Systems)

Main features are:


The Digital Closed Loop Bump & Blip achieved Double Isle of Man TT Victories on 2012 debut in the hands of now 17 times Sidecar TT Winning legend Dave Molyneux who commented:

"The Pro-Shift Closed Loop Bump & Blip System was flawless, the fastest clutchless upshifts I've ever seen allied to the precise DBS™ Auto-Blipped Downshifts make this system very special indeed, it increased acceleration, stabilized the bike whilst downshifting which allowed me to brake later, it was a pleasure to use & most definitely added speed"

I had a safe journey home as I took things nice & steady with the new Pro-Shift PS3.5 System installed on my Caterham 7... Then I went for a drive last weekend and WOW, the 7 is now so so fast, I've even said scary fast to some!.. Lovin' it!!!

Finally I could try DBS™ at the Mallorca Ciruit 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!

VG Motorsport Racing with a Rage buggy using Pro-Shift System, managed to finish the Rally-Greece off-road 2017 edition - 7th overall, 3rd in class, 1st Greek Team out of 34 Competitors!

Thank you all !!!!

The new B&B II with strain gauge is FANTASTIC!.. An Awesome race weekend, I rode it and found it to work flawlessly. The ability to micro adjust just turns it into night and day. It was easy and worked perfectly... I was impressed!


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!

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!

MIKE CASON (UK) November 2 2014

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!!!

ROBERT GUY (UK) August 10 2016

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 (UK) May 24 2016

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

LUIS HENRIQUE A. MONTEIRO (Brazil) February 14 2016

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.
