Riders choose this kit when they want a durable foundation for a rebuild that offers a strong step up in compression over stock without needing oversize bores.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eForged construction is the core of this kit, giving it the strength to handle demanding riding conditions. ArmorGlide skirt coating reduces friction and helps prevent scuffing, while force-fed pin oiling delivers lubrication directly to the piston pin. The 10.5:1 compression ratio is the feature most riders look for when aiming for improved throttle response and torque.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eThis standard-size kit is best suited to engines with healthy cylinder bores that do not require an oversize piston. It is a practical, well-engineered choice for a V-twin refresh where reliability and a noticeable performance gain are the priorities.\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 K0210PS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Piston Kits \u0026amp; Components\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:\u003c\/strong\u003e 96-103 cu in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Standard\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;\"\u003eWhat compression ratio does this piston kit have?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThe Wiseco Tracker Piston Kit has a 10.5:1 compression ratio.\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 is the piston pin lubricated?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThe kit uses force-fed pin oiling to provide critical 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 size bore is this kit designed for?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThis is a standard-size kit, intended for engines with healthy cylinder bores that do not require an oversize.\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 compression ratio does this piston kit have?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The Wiseco Tracker Piston Kit has a 10.5:1 compression ratio.\"}}, {\"@type\": \"Question\", \"name\": \"How is the piston pin lubricated?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The kit uses force-fed pin oiling to provide critical lubrication to the piston pin.\"}}, {\"@type\": \"Question\", \"name\": \"What size bore is this kit designed for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This is a standard-size kit, intended for engines with healthy cylinder bores that do not require an oversize.\"}}]}\u003c\/script\u003e\n\u003c!-- vt:seo-end --\u003e","brand":"Wiseco","offers":[{"title":"Default Title","offer_id":53035850629231,"sku":"K0210PS","price":322.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/a743-5c818a776c2db_a70493e3-e3a0-4465-9e23-c05d0d77da97.jpg?v=1777529735","url":"https:\/\/vtwinbikers.com\/products\/wiseco-tracker-piston-kit-96-to-103-4-375-stroke-10-5-1-std-k0210ps","provider":"VTWIN BIKERS","version":"1.0","type":"link"}
