Performance Tuning

BSD Performance has a very simple approach to tuning today’s complex motorcycles. We combine old-fashioned engine know-how with what we learn working at the cutting edge of two-wheeled technology — such as ECU reprogramming and traction control — with the simple desire to do the job right, no matter how large or small.

The full range of options — from mild-mannered to off-the-scale fast!


Our service options are tailored to the customer’s needs, from the major valve clearance service to as little as an oil and filter change for all fuel injected or carburettor motorcycles.

Dyno results

New for the website is our leaderboard, which shows the rankings for bhp and torque, for the bikes we have on our dyno!

This a list of bikes that we have either ecu re-mapped, mapped through a Power Commander or the Rapid Bike add on module, which are the most popular ways of mapping currently.

When I first brought in my GSXS1000 it was awful to ride! A lot of time a effort was spent on the bike to get it right, they did a fantastic job on the bike and were helpful throughout the entire process! The bike now rides how it should do.

Really good service. The work on the bike transformed it entirely (Sprint ST 1050). The difference was immediately noticeable. Far better than it ever was stock. Dramatically smoother rolling on the throttle from closed, still plenty of punch in the midrange, and the bike pulls strongly from 5k all the way to the redline. The staff are all really friendly and helpful and I even got some much appreciated advice on suspension set up.

From the outset the bike is transformed. The flat spot is gone. But the most impressive change is that direct and constant feel of power delivery I now have at the throttle. Riding back through the rain and road debris I had the control and confidence that wasn't there the night before. As a road rider your work is the best investment I have made in the machine.
