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!

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!!!

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

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. 

TOM ELLIS (UK) May 10 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

Just to let you know, the autoblipper system works brilliantly thank you! 


I love the product and the service, this thing is amazing I need one for my street car, one of the best mods I've bought for my car.  Thank you, thank you, thank you.
