Emissions Compliance Declaration: QUALIFIED MANUFACTURER DECLARED "REPLACEMENT PART"


WARNING: Cancer and Reproductive harm - www.p65warnings.ca.gov


The KTM 790 Adventure/Adventure R is hands down the most anticipated adventure bike for 2019. KTM has put an incredible machine together for today's more aggressive ADV riders.

We started off by developing our Works Finish RS-4 muffler profile to compliment power delivery. This new KTM responded to our design even more than we had hoped, increasing 5.5% in max HP, and 4.7% in max torque. To add to the aesthetics and protection we included a carbon heal guard. That Yoshimura power and rumble that our RS-4 delivers is perfect for both on and off-road adventures.

Yoshimura RS-4 Slip-on weight 7.7 lbs vs Stock muffler weight 7.9 lbs.

Proudly made in the USA!

STREET SERIES EXHAUST SYSTEM

Open tab
All Street Series systems are Slip-on / Bolt-on applications that do not require tampering with the vehicle's emissions control system, yet still deliver that special spirit the world has come to expect from the legendary company known as Yoshimura. Street Series applications cover all of the iconic profiles that Yoshimura has become famous for. From the legendary tri-oval profiles to the refined ALPHA mufflers, and even our R-55 angular masterpieces. Our Street Series exhaust offer street-legal options for almost everything on two wheels.

Works Finish Explained

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

    Brings my 790 R to life!

    Super happy with the weight savings and finish work to my new RS-4. But really pumped on how strong hit pulls through the upper rpm. The sweet bark it makes is a bonus. Now I can actually hear my 790 R churring out the power! Thanks Yosh for making a killer exhaust!!!!

    Thanx,

    Randy Commans
