Riders choose it for a rebuild or for a performance build that needs a solid, durable base.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eThe forged piston crown is built for strength, and the ArmorGlide skirt coating reduces friction and scuffing for smoother operation. Force-fed pin oiling enhances lubrication under load, helping the assembly hold up when pressure is high. The 10.5:1 compression ratio is intended to deliver power gains and improved throttle response across the rev range.\n\nThis is a +.020 oversized kit, which suits engines whose cylinder walls need a bore to clean up, or builds that call for an oversized piston. Cylinders should be bored and honed to the exact specification for these pistons to achieve the intended performance and longevity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor off-road \/ closed-course race use only.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3 style=\"margin:20px 0 6px;\"\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Wiseco\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e K0210P2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompression Ratio:\u003c\/strong\u003e 10.5:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke:\u003c\/strong\u003e 4.375 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement Range:\u003c\/strong\u003e 96-103 cubic-inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize:\u003c\/strong\u003e +.020\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Forged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSkirt Coating:\u003c\/strong\u003e ArmorGlide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.75 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"margin:22px 0 8px;\"\u003eCommon questions\u003c\/h3\u003e\u003cdiv class=\"vt-faq\"\u003e\n\u003cdiv style=\"margin:0 0 12px;\"\u003e\n\u003cp style=\"margin:0 0 3px;font-weight:600;\"\u003eIs the piston construction forged?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eYes, the Wiseco Tracker Piston Kit uses forged construction for extreme strength.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin:0 0 12px;\"\u003e\n\u003cp style=\"margin:0 0 3px;font-weight:600;\"\u003eWhat is the compression ratio of this kit?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThe kit has a 10.5:1 compression ratio, which is intended to provide power gains.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin:0 0 12px;\"\u003e\n\u003cp style=\"margin:0 0 3px;font-weight:600;\"\u003eWhat is the oversize of this piston kit?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThis is a +.020 oversized kit, so cylinders should be bored and honed to the exact specification for these pistons.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is the piston construction forged?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes, the Wiseco Tracker Piston Kit uses forged construction for extreme strength.\"}}, {\"@type\": \"Question\", \"name\": \"What is the compression ratio of this kit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The kit has a 10.5:1 compression ratio, which is intended to provide power gains.\"}}, {\"@type\": \"Question\", \"name\": \"What is the oversize of this piston kit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This is a +.020 oversized kit, so cylinders should be bored and honed to the exact specification for these pistons.\"}}]}\u003c\/script\u003e\n\u003c!-- vt:seo-end --\u003e","brand":"Wiseco","offers":[{"title":"Default Title","offer_id":53035850563695,"sku":"K0210P2","price":322.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/a743-5c818a776c2db_3d84f362-50e7-400b-8073-2cd02e722ef3.jpg?v=1777529734","url":"https:\/\/vtwinbikers.com\/products\/wiseco-tracker-piston-kit-96-to-103-4-375-stroke-10-5-1-020-k0210p2","provider":"VTWIN BIKERS","version":"1.0","type":"link"}
