YOSHIMURA - KTM 790 / 890 / HUSQVARNA NORDEN 901 - RS-4 SLIP-ON

Fitment: 2019-2023 KTM 790 /890 Adventure and 2022-2023 Husqvarna Norden 901 Yoshimura started off by developing their Works Finish RS-4 muffler profile to compliment the KTM's power delivery. In response, the bike increased 5.5% in max HP, and 4.7% in max torque. To add to the aesthetics and protection they included a carbon heal guard. That Yoshimura power and rumble that the RS-4 delivers is perfect for both on and off-road adventures.
