At DMG Motorsports, we present the EBC CSK103 Clutch Spring Kit—a performance-focused upgrade designed to help minimize clutch slip, reduce plate wear, and improve power transfer to the ground. These springs are 15% stiffer than original equipment and use thicker winding material to provide increased clamp pressure. The exact CSK103 kit contains six clutch springs and is listed for 1987–1988 Yamaha BW350 applications.
