Forged piston crowns give these pistons strength, and the generous valve pockets are designed to accommodate bigger valves for riders building an engine for more performance.\n\nRiders choose this kit for the higher compression it provides, which is aimed at improving throttle response and power. Each piston carries an ArmorGlide skirt coating that reduces friction and improves scuff resistance. Force-fed pin oiling delivers added lubrication to the piston pin, supporting durability under demanding operation.\n\nThe kit is specified for a 4.000-inch stroke and is well suited to a rebuild where the cylinder walls are being cleaned up with the oversized bore. Proper cylinder boring and honing are required, and a dyno tune is recommended to make full use of the increased compression.\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\u003ePart Number:\u003c\/strong\u003e K0208P1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Wiseco\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement:\u003c\/strong\u003e 88 cubic 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\u003eBore Size:\u003c\/strong\u003e +.010 inch oversize\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke:\u003c\/strong\u003e 4.000 inch\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 compression ratio of this piston kit?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThis Wiseco Tracker kit is built for 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;\"\u003eWhat is the skirt coating on these pistons?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eEach piston features an ArmorGlide skirt coating that reduces friction and improves scuff resistance.\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;\"\u003eDo the pistons have valve pockets for larger valves?\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eYes, the forged piston crowns include valve pockets that accommodate big-valve cylinder heads.\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 compression ratio of this piston kit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This Wiseco Tracker kit is built for a 10.5:1 compression ratio.\"}}, {\"@type\": \"Question\", \"name\": \"What is the skirt coating on these pistons?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Each piston features an ArmorGlide skirt coating that reduces friction and improves scuff resistance.\"}}, {\"@type\": \"Question\", \"name\": \"Do the pistons have valve pockets for larger valves?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes, the forged piston crowns include valve pockets that accommodate big-valve cylinder heads.\"}}]}\u003c\/script\u003e\n\u003c!-- vt:seo-end --\u003e","brand":"Wiseco","offers":[{"title":"Default Title","offer_id":53035850301551,"sku":"K0208P1","price":322.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/a743-5c818a776c2db_22f64efe-57b2-41e6-aee8-ef376e96a7fe.jpg?v=1777529732","url":"https:\/\/vtwinbikers.com\/products\/wiseco-tracker-piston-kit-88-to-95-4-000-stroke-10-5-1-010-k0208p1","provider":"VTWIN BIKERS","version":"1.0","type":"link"}
