GSG Performance

GSG Performance is an independent motorcycle performance workshop based at Knockhill Racing Circuit in Fife, Scotland. Serving road riders, trackday enthusiasts and racers, the business combines hands-on engineering expertise with advanced tuning and diagnostic technology to improve motorcycle performance and reliability. It is a certified Dynojet Tuning Centre and K-Tech Suspension Service Centre.

Services include custom dyno tuning and ECU re-flashing, with fuel mapping designed to improve throttle response, optimise power delivery and address flat spots. Tuning is tailored to each motorcycle, setup and riding style rather than relying on generic maps. GSG Performance also provides suspension servicing and setup for K-Tech, Öhlins, WP, Showa and KYB units, with adjustments suited to the rider’s weight and needs.

The workshop carries out routine maintenance, track preparation and full track-ready builds, as well as precision diagnostics to investigate running issues. With a data-led approach and attention to detail, GSG Performance aims to deliver smooth, usable performance for road, trackday and race use.
