Yoshimura RS-4 Stainless Steel 'Works Finish' Carbon End Cap Slip-On Silencer

This RS-4 silencer, like every slip on that Yoshimura make, is specifically designed for the new Honda CRF1000 Africa Twin to unleash the power, sound and style that can only be Yoshimura.

Removing the stock muffler saves over 4 pounds (2Kg) and makes the 988cc parallel twin engine growl!

• Oval-ellipse shaped sleeve
• Yoshimura's Works Finish for increased durability and adventure friendly design
• Features an integrated inlet heat shield design for a seamless transition with the stock heat shield

The new Yoshimura Works Finish takes on a unique colouring 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 colouration
• Increased fatigue strength
• Increased scratch and stain resistance

Yoshimura R&D has developed the current generation RS4 for Adventure Bikes — a design that provides an unrivalled combination of power and a quiet exhaust note. The RS4 features a Pentagonal stainless steel muffler sleeve for increased durability.

The front end-cap has a noise reducing Polyresonant duplex chamber, the rear a turned out carbon cap. All parts required for fitment are included (fittings/link pipe etc.) with full fitting instructions and is developed to fit without fuel modification.
