Product Details
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. (Note: Inserts for R77 Mufflers will not fit this muffler)
Proudly made in the USA
New Yoshimura Works Finish takes on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components our factory racers use.
- Contemporary Satin/matte finish
- Uniform heat coloration
- Increased fatigue strength
- Increased scratch and stain resistance
