Italkit has redesigned its geometry to reduce the risk of failures caused by the piston ring, a problem that can end up damaging both the piston and the cylinder itself.\u003c\/p\u003e\n\u003cp\u003eWith this new configuration, the aim is to achieve a \u003cstrong\u003elonger cylinder service life without compromising performance\u003c\/strong\u003e, making it an especially interesting option when it is time to renew the top end of the engine and correct one of its critical points.\u003c\/p\u003e\n\u003cp\u003eThe cylinder is made of \u003cstrong\u003ealuminum-silicon alloy (Al-Si)\u003c\/strong\u003e and uses a \u003cstrong\u003eNikasil inner coating\u003c\/strong\u003e. This combination offers high wear resistance and good heat dissipation, something especially important in a 2-Stroke engine that usually operates at \u003cstrong\u003ehigh revs and temperatures\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe kit includes a \u003cstrong\u003e1-ring piston with a domed crown\u003c\/strong\u003e, an ideal option in 2-Stroke engines due to its smaller contact surface and lower friction compared with a 2-ring piston. This allows for a \u003cstrong\u003equicker engine response, better ability to gain revs, and lower mechanical drag.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy install this cylinder?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRedesigned rear transfer port\u003c\/strong\u003e to reduce the risk of failures related to the piston ring.\u003c\/li\u003e\n\u003cli\u003eGreater \u003cstrong\u003ereliability and durability\u003c\/strong\u003e of the engine top end.\u003c\/li\u003e\n\u003cli\u003eMade from \u003cstrong\u003ealuminum-silicon\u003c\/strong\u003e for good heat dissipation.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNikasil\u003c\/strong\u003e coating with high wear resistance.\u003c\/li\u003e\n\u003cli\u003eMaintains a configuration designed for \u003cstrong\u003ehigh performance\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eA good option for \u003cstrong\u003erebuilding the top end\u003c\/strong\u003e of an engine that already shows wear.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThe kit includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItalkit Cylinder Ø47 mm\u003c\/strong\u003e in aluminum-silicon with Nikasil coating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-ring piston with domed crown\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eTop-end gasket set.\u003c\/li\u003e\n\u003cli\u003ePiston pin bearing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCylinder head insert not included.\u003c\/strong\u003e Italkit offers different Ø47 mm cylinder head insert configurations to adapt the assembly to the type of piston and the level of tuning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailable cylinder head inserts:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCU.34.85.1:\u003c\/strong\u003e for domed-crown piston, compatible with kit CI.34.085.G.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCU.34.85.1A:\u003c\/strong\u003e high-compression version for domed-crown piston.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCU.34.85.2:\u003c\/strong\u003e for Italkit 4279\/1 piston with 10° crown.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCU.12.85.3:\u003c\/strong\u003e for Italkit 2984M piston with 12° crown.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible models\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKTM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e85 SX 2018-2025\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eGASGAS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMC 85 2021-2025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Italkit","offers":[{"title":"Default Title","offer_id":67612859990407,"sku":"CI.34.085.G","price":479.16,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0860\/6223\/5959\/files\/CI.34.085.G.png?v=1790930340","url":"https:\/\/motoscoot.net\/en\/products\/cylinder-italkit-d-47mm-ktm-85-sx-18-25-gas-gas-mc-21-25","provider":"Motoscoot","version":"1.0","type":"link"}
