It is built around a 4.375-inch stroke and a 10.5:1 compression ratio, and is offered in a +.010 oversize.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eRiders choose this kit when they want durable internals for performance riding. The forged piston crown is built to withstand demanding use, and the crown includes generous valve pockets to accommodate big valves. Force-fed pin oiling delivers lubrication directly to the pin, and the ArmorGlide skirt coating reduces friction while improving scuff resistance.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eThe 10.5:1 compression ratio offers a noticeable performance increase without requiring extreme modifications, which makes it a practical option for a range of V-twin builds. Whether refreshing an older motor or looking for more power from a newer one, this kit provides a robust foundation for a more reliable engine.\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 K0210P1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Piston Kits \u0026amp; Components\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement:\u003c\/strong\u003e 96 to 103 cubic-inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke:\u003c\/strong\u003e 4.375 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompression Ratio:\u003c\/strong\u003e 10.5:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize:\u003c\/strong\u003e +.010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Crown:\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;\"\u003eWhat is the piston crown made from?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThe piston crown is forged for durability and includes generous valve pockets for big valves.\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;\"\u003eHow does the kit handle lubrication?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eIt uses force-fed pin oiling to provide enhanced lubrication to the piston pin.\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 does the ArmorGlide skirt coating do?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThe ArmorGlide coating reduces friction on the piston skirt and improves scuff resistance.\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\": \"What is the piston crown made from?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The piston crown is forged for durability and includes generous valve pockets for big valves.\"}}, {\"@type\": \"Question\", \"name\": \"How does the kit handle lubrication?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It uses force-fed pin oiling to provide enhanced lubrication to the piston pin.\"}}, {\"@type\": \"Question\", \"name\": \"What does the ArmorGlide skirt coating do?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The ArmorGlide coating reduces friction on the piston skirt and improves scuff resistance.\"}}]}\u003c\/script\u003e\n\u003c!-- vt:seo-end --\u003e","brand":"Wiseco","offers":[{"title":"Default Title","offer_id":53035850530927,"sku":"K0210P1","price":322.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/a743-5c818a776c2db_ee08567f-56f8-4885-bc8c-cfa1a0413f4d.jpg?v=1777529735","url":"https:\/\/vtwinbikers.com\/products\/wiseco-tracker-piston-kit-96-to-103-4-375-stroke-10-5-1-010-k0210p1","provider":"VTWIN BIKERS","version":"1.0","type":"link"}
