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.

Our leading technicians have been working with the Honda MSX 125 and as a result we are offering a line-up of performance MSX products. Riders can choose from the slip-on or full system and for those riders who’d prefer to upgrade in stages we’re offering the header pipe as a standalone kit.

Our precision engineered exhausts are fabricated using premium high thermal tolerance T304 “aerospace” grade stainless steel tube that will endure through the harshest of conditions, combined with our CNC Mandrel bent large bore design pipework which permits maximum performance by allowing a greater flow of exhaust gas. The fact that installation of this Scorpion system requires no changes to the bikes standard settings, doesn't require a remap and the OE system does not require cutting for installation this as a result, allows for straightforward installation when using the provided fitting kit.

Riders will be able to indulge in a more tantalising tone with a much deeper sportier acoustic range that will epitomize the enduring quality of this product throughout its lifetime of service. Also instantly noticing a sharper throttle response and increase in bhp. These improvements can be chalked down to the manufacturing process, high-flow silencer and our beneficial dose of weight reduction which can all take a bikes rideability to the next level! Because when machine meets road your exhaust system is a key component of its performance. 

Our silencer style options listed below allow for Riders to professionally tailor their bikes aesthetics with our handpicked range of silencer finishes which utilise our unrivalled build quality to maintain longevity and peak performance on the roads. We’re offering our signature Red Power silencer finished in either black ceramic or brushed stainless.


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.
