Since starting production of their own motorcycles in the mid 1950’s Honda have grown to be one of the largest two-wheel manufacturers in the world. Soichiro Honda always had a passion for motorsport so it was inevitable that before long they would race bikes in Grand Prix and the iconic Isle of Man TT with Mike Hailwood securing their first senior TT win in 1966. The formation of Honda Racing Corporation (HRC) in 1982 saw them debut their first two-stroke race bike the NS500 which went on to win the Grand Prix world championship in 1984 and since then Honda has been a dominant force in Grand Prix racing winning numerous championships and heads the number of wins at the TT.  From the mid 1990’s Scorpion have been producing performance exhausts for a huge range of Honda Motorcycles whilst passing on our knowledge and experience gained from working with the Ron Haslam Race School and numerous race teams over the years. 


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.
