Yoshimura - RS-4 Signature Series Full System - 2019 KTM 250SX-F, 350 SX-F and 2019 Husqvarna 350 FC
Carbon fibre end-cap, Stainless Steel Tail-pipe
The Yoshimura RS-4 Signature series full exhaust system has been developed to win races. Adding power throughout the range and providing torque to help the bike get out of the gate to grab holeshots, the RS-4 system gives the rider confidence to battle with the best. The RS-4 has also been designed to save weight and add monster performance over the stock system. The unique Pentagonal-shape sleeve gives your bike that factory look while adding an exhaust note that isn’t loud thanks to the Polyresonant duplex chamber and two staged stepped baffle for increased performance. Adding to the factory look, the RS-4 includes a Stainless Steel header pipe that is durable and is finished off with a Carbon Fibre cone end cap.
For riders looking to shave off even more weight, the RS-4 Signature series comes in two Titanium versions to match anyone’s factory look. Yoshimura has done it again and offered factory equipment for any rider looking to increase power on their motocross bike!
