Yoshimura Introduces 2019 KTM 790 Adventure RS-4 Slip-on

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.

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

Stock muffler weight: 7.9  Lbs.
Yoshimura RS-4 Slip-on weight: 7.7 Lbs.
