Our customer feedback

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

Shaan Shareef

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!

Jay Kinberger

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!

Jorge Piza

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

For me as a disabled person, the PSU has helped me ride a motorcycle again. I have lost balance and nowadays prefer to ride a trike, I have used the PSU for about 15000 kilometres now and found it a great help! Now me and my lifelong partner enjoy the rides and make people and other riders turn their heads when we arrive at places, we are also members of the Wing Riders Golwing Club and take part in all rides and activities every month!
