Yoshimura Signature RS-4 S/O - KTM 450 SX-F 2016

Introducing the brand-new RS-4 Slip-On system from Yoshimura R & D of America.

Yoshimura took the time to develop and test in order to deliver the best exhaust system available for the new KTM 450, and the results were worth the wait. We took everything we have learned over the last several years with our world famous RS-4 muffler and revised it with the latest materials and an updated spec that makes this new model perform.

It's time to change the exhaust on your KTM to Yoshimura.

• Pentagonal-shaped sleeve
• Front muffler cap functions as a polyresonant chamber which helps reduce noise
