Slip-on Silencer Cyclone

The traditional design of the Slip-On Silencer Cyclone features a ring on the end of the silencer and the "YOSHIMURA" logo is engraved by laser marking for a high-quality look. In addition, the position and angle of the silencer give a sporty impression. There are 4 types of silencer covers to choose from, and a lightweight carbon type is also available.

Even though it is a slip-on silencer type with excellent cost performance to replace only the silencer and tailpipe, the increased power output at high rpm will bring a strong acceleration feeling. In addition, the weight reduction will further enhance the performance of the CB400SF/SB in areas not shown on the power graph. The sound of the inline four-cylinder engine is more elongated and profound, which enhances the feeling of excitement when riding.
