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 YFZ450\u003cbr\u003eYamaha YFZ450R\u003cbr\u003e\u003c\/p\u003e","brand":"Vertex","offers":[{"title":"12.0:1 \/ A' Piston For Brand New Cylinder 94.95mm","offer_id":53947665187157,"sku":"VT2984A","price":142.8,"currency_code":"GBP","in_stock":true},{"title":"12.0:1 \/ B' Piston For Part Worn Cylinder 94.96mm (0.01mm Larger)","offer_id":53947665219925,"sku":"VT2984B","price":142.8,"currency_code":"GBP","in_stock":false},{"title":"12.0:1 \/ C' Piston For Highly Worn Cylinder 94.97mm (0.02mm Larger)","offer_id":53947665252693,"sku":"VT2984C","price":142.8,"currency_code":"GBP","in_stock":false},{"title":"13:01 \/ A' Piston For Brand New Cylinder 94.95mm","offer_id":53947665285461,"sku":"VT3551A","price":160.0,"currency_code":"GBP","in_stock":false},{"title":"13:01 \/ B' Piston For Part Worn Cylinder 94.96mm (0.01mm Larger)","offer_id":53947665318229,"sku":"VT3551B","price":160.0,"currency_code":"GBP","in_stock":true},{"title":"13:01 \/ C' Piston For Highly Worn Cylinder 94.97mm (0.02mm Larger)","offer_id":53947665350997,"sku":"VT3551C","price":160.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0880\/0528\/0085\/files\/VT2984.webp?v=1779101159","url":"https:\/\/tradeparts.aceatv.co.uk\/products\/piston-kit-stock-bore-for-yamaha-yfz450-r","provider":"Ace ATV Trade (Parts)","version":"1.0","type":"link"}
