To handle the internal pressures of a four-stroke engine, Vertex's four-stroke pistons are forged from the highest quality 2618 aluminium alloy for superior strength and durability. Vertex also utilises a T-box forging on their highest compression pistons. This new design builds on Vertex's outstanding dedication to quality by making it more durable and able to handle even the most demanding rigours better than ever before. Vertex also uses proprietary piston profiles and compression ratios offered in A, B, C and D sizes to maximise power and performance while reducing blow-by and oil consumption. \u003c\/p\u003e\n\u003cp\u003eAll Vertex Pistons Feature:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKits include piston, rings, wrist pin and circlips\u003c\/li\u003e\n\u003cli\u003eAll pistons are heat treated with a T-5 or T-6 hardening and tempering cycle.\u003c\/li\u003e\n\u003cli\u003eReplacement rings are sold individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eNote: Please ensure you have measured and selected the correct size piston.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eBIKE FITMENT\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eYAMAHA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWR450F 2021-2023\u003c\/li\u003e\n\u003cli\u003eYZ450F 2020-2022\u003c\/li\u003e\n\u003cli\u003eYZ450FX 2021-2023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERTEX","offers":[{"title":"A","offer_id":48606178574620,"sku":"24448A","price":439.95,"currency_code":"AUD","in_stock":true},{"title":"B","offer_id":48606178607388,"sku":"24448B","price":439.95,"currency_code":"AUD","in_stock":true},{"title":"C","offer_id":48606178640156,"sku":"24448C","price":439.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/7707\/1132\/files\/MOTOHOUSE_WEBSITE_1_f33eda7d-4f86-47c1-9aa6-63bf5b891607.png?v=1794143514","url":"https:\/\/www.motohouse.com.au\/products\/vertex-12-8-1-comp-piston-kit-yamaha-yz450f-20-22-yz450fx-wr450f-21-24","provider":"Moto House","version":"1.0","type":"link"}
