Bidalot developed completely new transfer and exhaust ports that perfectly match the 47.6 mm bore. The goal was to deliver very high power at high rpm without compromising torque and mid-range performance.\u003c\/p\u003e\n\u003cp\u003e The piston is made of an extremely heat-resistant and very high mileage aluminum-silicon alloy.\u003c\/p\u003e \u003cp\u003eThe one-piece CAD-designed cylinder head features a self-centering combustion chamber. The cylinder head protrudes 2.4 mm into the bore. The water jacket has been redesigned and adapted to the new transfer ports. The material thickness is consistent to ensure consistent thermal stability. The outlet is flushed directly, and the water then flows to the cylinder head, where it cools the combustion chamber, ensuring perfect overall cooling.\u003c\/p\u003e\n\u003cp\u003e The timing and compression are designed for racing use (±193° exhaust, ±132° transfer, with a compression ratio of 15.8-16.0 to 1).\u003c\/p\u003e \u003cp\u003e\u003cem\u003ePlease note:\u003c\/em\u003e When installing this racing cylinder, the setup must be completed with appropriate high-end tuning components: reinforced racing crankshaft (with 90mm connecting rod and 44.9mm stroke), internal rotor ignition, VForce reed valve block, larger carburetor (32mm), reinforced clutch, etc. As this is a truly high-end part, you need to have the appropriate know-how!\u003c\/p\u003e\n\u003cp\u003e The cylinder is equipped with a special 4-hole flange, but can also be mounted with a 2-hole flange with a 50 mm centre distance. \u003c\/p\u003e\n\u003ch3 style=\"margin: 25px 0px 15px; font-family: Barlow, sans-serif; font-weight: bold; color: #000000; text-transform: uppercase; overflow-wrap: break-word; word-break: break-word; hyphens: auto; font-size: 1.25rem; line-height: 1.3125; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgba(242, 242, 242, 0.3); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e Technical information Bidalot RF80WR\u003cspan style=\"text-decoration: underline;\"\u003e\u003c\/span\u003e\n\n\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e Aluminum cylinder with Nikasil coating\u003c\/li\u003e\n\n\u003cli\u003e 6 transfer ports - output with boost ports\u003c\/li\u003e\n\n\u003cli\u003e Aluminum-silicon alloy piston, 47.6 mm\u003c\/li\u003e\n\n\u003cli\u003e Chrome plated piston ring, d. 47.6x1mm\u003c\/li\u003e\n\n\u003cli\u003e Incl. gaskets, O-rings, screws and studs (length 124 mm)\u003c\/li\u003e\n\n\u003cli\u003e Flange D.28x30mm - 4 screws\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Billaricambi SRLS","offers":[{"title":"Default Title","offer_id":49334043345220,"sku":"BID11000783","price":529.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0856\/3730\/0548\/files\/574352_4699208-1.jpg?v=1755940776","url":"https:\/\/www.billaricambi.it\/en\/products\/gruppo-termico-bidalot-racing-factory-80-wr-derbi-euro-3-euro-4","provider":"Billaricambi SRLS","version":"1.0","type":"link"}
