The new Works Finish Alpha T slip on for the 2017+ KTM 390 Duke adds the distinctive Yoshimura sound and provides the 390 single cylinder engine 11% peak H.P. and 17% peak torque. Made in the USA.

My personal thanks to Greg Hatcher. I received the item in great nick after paying applicable custom duty. The item is top notch it looks and sounds the part. Great piece of kit. I have installed it on my 2017 Duke 250. Hail Yoshimura……
