Japanese manufacturer Suzuki first began producing motorcycles in the 1950’s steadily growing to be one of the big four Japanese manufacturers. A long history in motorsport started initially in Motocross before moving onto circuit racing culminating with several 500cc World Championships and numerous wins in Superbike series. Suzuki turned the sports bike market on it’s head in the 1980’s with the release of the GSX-R750 the first of their legendary GSX-R series of models which have gone on to be one of the most sought after marques available. Scorpion has a long history of producing performance exhausts for Suzuki models across all ranges from the GSX-R125 through to the Hayabusa.


Nothing beats that feeling of knowing you’re riding on an authentic race grade product and Scorpion pretty much pioneered the concept of technology transfer by sharing everything which works on the track with you the rider.

Ultra-light weight materials, hours spent on the dyno and durability testing is at the heart of our extensive development program. From the moment you fire up your new Scorpion, the heart begins to race, and adrenalin starts to flow. Upgrade to Scorpion and bring out the racer in you.
