Our customer feedback

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

I have had a Pro-Shift system installed in my Escort MK2/ Tractive Gearbox now for a number of years and it has operated faultlessly throughout. The Pro-Shift team are without doubt the perfect example of what customer service and support should be. Highly recommended!

Ian Wante

One of the best quick shifters on the market today, with the advantage of being able to tailor make the system to your requirements!

Dave Clark

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!
