"RS-4J" is a cyclone that combines Yoshimura Japan's technology with US Yoshimura's "RS-4" silencer design for motocross, which is active in AMA Supercross and other events. The cone end uses a luxurious carbon material. The front side of the silencer is laser marked with ``RS-4J'', and the ``double emblem'' with an emblem on the back side is standard specification, and we are particular about details. The lineup includes slip-on specifications that are easy to replace. Approximately 40% lighter than the standard muffler (STD: 5.1Kg, RS-4J titanium cover: 3.1Kg).
