KTM 390 Duke 17-20
2017 - 2020

With its history dating back to the 1930’s KTM has a chequered past of highs and lows but since the 1990’s the Austrian manufacturer has been going from strength to strength and in that time has grown to be one of the most successful brands in motorsports with numerous Dakar Rally victories to name a few. Since the launch of their first street bike in 1994 KTM have been quick to pass on their knowledge gained through motorsport making them one of the most sought-after brands around. Scorpions’ performance exhausts perfectly compliment the KTM’s looks and performance but most of all give a deeper sportier tone than the OEM exhaust.

Our leading technicians have developed through rigorous trial and testing a half system for the DUKE 390. Using dynamometer development combined with track to road technology Scorpion exhausts are cutting-edge performance products. Our branding is a hallmark for precision engineered exhausts, fabricated using premium high thermal tolerance T304 aerospace grade stainless steel tube that will endure through the harshest of conditions. We shape our pipework using CNC Mandrel bent large bore design which permits maximum performance by allowing a greater flow of exhaust gas. 

Installation of this Scorpion system requires no changes to the bikes standard settings nor a remap. The OE system doesn’t require cutting for installation and as a result allows for straightforward installation when using our official Scorpion fitting guides. 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.

Scorpion exhausts provide a sharper throttle response and an increase in bhp. These improvements can be chalked down to our manufacturing process, high-flow silencer and healthy dose of weight reduction. With all these factors packed into our exhaust it’s no-wonder that upgrading a motorcycle with Scorpion has been described as taking a bikes rideability to the next level and transforming the riding experience!

Our signature silencers are instantly recognisable due to popularity with motorcyclists worldwide, maintaining the unchanging standard of unrivalled Scorpion build-quality. The silencer is not only one the most technically intricate components of the exhaust system but one of the most visually eye-catching. For this reason, we offer a selection of silencer styles and finishes depending on motorcycle model and manufacturer. The DUKE 390 can be fitted with the Serket Taper or Red Power style of silencer, our Serket Taper silencer can be finished in either carbon-fibre or stainless steel and the Red Power silencer is offered in brushed stainless or black ceramic.

Riders wanting to take the next step in exhaust performance, Scorpion technicians have provided the solution with our de-cat pipework. The de-cat pipework removes the bulky OE catalyst resulting in unobstructed gas-flow and is perfectly engineered for those riders pushing the boundaries of exhaust performance.
