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.
