KTM and Husqvarna have introduced LE and Rockstar Editions for 2018 and now Yoshimura is ready to add to the experience of these awesome dirt bikes.

We developed the RS-4 in the R&D lab called the Motocross track. The RS-4 boasts its own resonance chamber and utilizes its volume and a unique baffling system to create the sound and power that is purely Yoshimura. With 450’s it’s not all about creating more power, it’s about creating more usable power and the RS-4 makes it happen.

Proudly made in the USA.

* Yoshimura Slip-on weight: 6.5 lbs. vs Stock Weight: 8.1 Lbs
