The WSM Piston Kit, designed for Yamaha engines, offers superior quality and durability with construction that meets or exceeds OEM standards. The pistons feature a nonabrasive MoS2 (Molybdenum Disulfide) coating that reduces heat and friction, contributing to increased power output and extended engine life. This coating actively draws heat through piston walls and out the bottom, promoting efficient cooling and enhancing performance under demanding conditions. The specially hardened tops add strength to the ring grooves, ensuring durability during high-stress operation.
Designed with an improved E-clip, this piston kit ensures a secure fit and reliable performance in each cylinder. The kit is ideal for those seeking a high-quality replacement to restore or boost engine performance, with each kit intended for a single cylinder application.
Constructed with precision, this piston kit is a reliable choice for Yamaha engines requiring a 67.00 mm piston, combining innovative features with robust materials to meet the demands of professional and recreational use.
