Introducing the newest RS-12 full system from Yoshimura R&D of America for the 2022.5 KTM SX-F Factory Edition/2023 SX-F 450 and 2022.5 Husqvarna Rockstar Edition FC450/2023 FC450. We got to work as soon as we could developing a system that would not only perform better than stock but one that would make the new 450's more controllable and more connected. Days of dyno and rider testing put our new RS-12 Signature Series exactly where we wanted it. Packing lots of punch for these two 450cc European machines.

This new system is the first Yoshimura production motocross exhaust to incorporate a resonator on the header and in the muffler. This new header resonator unlocks bottom and midrange power to not only make the new Austrian bikes more powerful, but provides more rider connectivity.

Spark arrestor sold separately.

The RS-12 proudly developed, designed, and made in the USA.
