The Yoshimura RS-4E racing system was designed to meet stringent FIM sound restriction standards while still maximizing power output across the entire rpm range. Additionally, the RS4E delivers improved durability between service intervals due to a unique internal configuration. The RS4-E has been tested and proven in the most brutal environments from the sands of Lommel, Belgium to the factory Supercross tracks in Southern California.
