    Excl. Tax: £116.73 Incl. Tax: £140.08

    technical features: Cylinder with increased 49mm bore, cast in aluminum light alloy to grant better heat stability. Barrel with Nikel-silicious coating; it better resists to wear and abrasion and it improves the piston sliding. The piston is die-cast at high silicon content with “omega” design; it allows containing thermic expansions and reducing stroke matching. Specific piston dome design also improves the compression ratio. It has two fine piston rings, the upper one of which is chromed while the scraper ring is composite. Kit comes complete with one-coat Inox steel head gasket with techno-polymer fluoride covering; it transfers the extreme temperatures and increases the burnt gas seal at high temperature. Fitting this kit may require adjustment of the carburettor and variator roller weights. It should only be fitted by someone with the mechanical ability and equipment to rebuild and set up the engine correctly . It is also recommended to increase the gear ratios to prevent over reving and reducing reliability of the engine. Learn More

    The aluminium cylinder, with closed-deck cooling system, features a specific working, which increases the thermal stability of the cylinder, cutting the risk of barrel distortion even at the highest temperature. The cylinder liner has a nickel -chrome coating. The head plane is brand new and innovative compared to the ones already present on the market: it features a nickel coating to avoid the detonation problems and then worked on with known process in advanced productive CNC centres that grind it with a centesimal calibration. In this way the head plane is perfectly coupled to the cylinder improving the combustion phase in the burning chamber and increasing the head and cylinder’s life It has 5 transfer ports plus an exhaust port with central bridge to optimise the gas scavenging The distribution diagram is brand new for its performance features. The piston is gravity die-cast in light alloy at high silicon content with a chromed, grinded, and lapped cast iron ring. The head is gravity die-cast from a block and later thermal treated to harden the material the same as for the cylinder: the mechanical resistance can be compared to a head machined from a block. CASE BORING AND CRANKSHAFT REPLACEMENT Before assembling the cylinder it’s necessary to bore the cases both in the crankshaft and in the cylinder housing. It is necessary to replace the original crankshaft with the new Polini 85mm one complete with coil. Learn More
