This kit features a piston with a durable nonabrasive MoS2 (Molybdenum Disulfide) coating that reduces heat and friction, enhancing power output and extending engine lifespan. The MoS2 coating actively draws heat away from the piston through the piston walls and disperses it out the bottom, contributing to better thermal management during operation. The piston’s specially hardened tops increase strength in the ring groove area, providing added durability under demanding conditions. An improved E-clip design ensures secure and reliable installation, simplifying maintenance and assembly. This kit is ideal for rebuilds and performance upgrades where longevity and efficiency are critical, with a size of 65.00 mm to match Yamaha engine specifications. Whether restoring an older engine or optimizing performance, the WSM Piston Kit delivers quality and reliability with proven materials and advanced features.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHigh-quality piston kit designed to meet or exceed OEM standards\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNonabrasive MoS2 coating reduces heat and friction for increased power and longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMoS2 coating effectively draws heat through piston walls and disperses it out the bottom\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSpecially hardened piston tops enhance strength in ring groove areas\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImproved E-clip design provides secure and reliable installation\u003c\/li\u003e\u003c\/ul\u003e","brand":"WSM","offers":[{"title":"Default Title","offer_id":50008272044272,"sku":"5052007","price":93.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/1980\/5424\/files\/269713.png?v=1783706733","url":"https:\/\/sublimepowersports.com\/products\/wsm-piston-kit-for-yamaha-50-520-07pk-65-00-mm-with-mos2-coating-and-hardened-tops","provider":"Sublime Powersports","version":"1.0","type":"link"}
