Yoshimura 16190BD520 Street RS-4 Works Finish Slip-on Exhaust, SS-SS-CF (Stainless steel, Stainless steel, Carbon Fiber) is made specifically for KTM 1090, 1190, 1290 Adventure Models.
In the world of Adventure bikes, KTM big bore bikes are held in very high regard. KTM 1290, 1190 and now with addition of the new 1090, the orange brand is aiming high at filling every desire of the adventure rider.
For those that want to compliment these three KTM machines, Yoshimura has developed an RS-4 slip-on that delivers in every area that an adventure rider would desires - power, sound and looks. The power that the RS-4 provides is second to none, delivering a 3.1% max gain in horsepower and a 2.7% max gain in torque. The sound the RS-4 provides is throatier, and with over a 5 lbs. weight loss, acceleration and throttle response has been improved dramatically. Finished off with Yoshimura's own Works Finish and you have a winner!
Included with each RS-4 is a sound insert. Optional spark arrestor (SA-04-K) is available separately.
Proudly made in the USA!
