Forged from the highest quality 2618 aluminium alloy, Vertex pistons are perfectly suited to handle the rigors and high pressures of today's modern four-stroke engines. Plus, to aid in the break-in process and reduce wear, every Vertex piston utilizes a unique Molybdenum Disulphide (MOS2) coating on the piston skirt.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWhat truly sets Vertex apart from the competition are the unique piston profiles and compression ratios that are offered in A, B and C sizes. This variation in sizing, a mere 0.004\", allows the piston to be perfectly sized to the cylinder for maximizing power and performance while reducing blow-by and oil consumption.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eCompatible with:\u003cbr\u003eYamaha Grizzly 660\u003cbr\u003e\u003c\/p\u003e","brand":"Vertex","offers":[{"title":"A' Piston For Brand New Cylinder 99.95mm","offer_id":53947667644757,"sku":"VT3104A","price":92.4,"currency_code":"GBP","in_stock":false},{"title":"B' Piston For Part Worn Cylinder 100.45mm (0.01mm Larger)","offer_id":53947667677525,"sku":"VT3104B","price":92.4,"currency_code":"GBP","in_stock":false},{"title":"C' Piston For Highly Worn Cylinder 100.95mm (0.02mm Larger)","offer_id":53947667710293,"sku":"VT3104C","price":92.4,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0880\/0528\/0085\/files\/PHOTO_COMING_SOON_2025_v3_4b78b786-4703-49d8-ad2c-2cfd1d36e0d8.webp?v=1779101165","url":"https:\/\/tradeparts.aceatv.co.uk\/products\/piston-kit-stock-bore-for-yamaha-grizzly-660","provider":"Ace ATV Trade (Parts)","version":"1.0","type":"link"}
