Casa Lambretta X2 225cc (70mm) tuning kit for Lambretta crankcase type TV SX DL 200cc + CasaCase. Direct heir to the famous X2 210cc, the new X2 has been extensively revised and updated with the usual Casa Lambretta quality. The aluminum cylinder has 5 ports and is supplied with the appropriate concentric head with the special fin design which significantly helps heat dissipation. The new double-ring piston, produced exclusively by Vertex, is forged and treated with a special Fluoro-Carbide coating, which significantly improves its smoothness. An absolute novelty is also the trapezoidal profile of the exhaust port with the "T shape" figure patented by Gilardoni, a Casa Lambretta world exclusive for Lambretta cylinders! The fifth work is obtained from fusion, more functional and safe. As always, the casting is carried out using a steel mould, which guarantees quality and perfection. All cylinders are always the same, no defects. The exhaust port threads are reinforced with a steel insert, impossible to damage them. To complete the cylinder, the X12a intake manifold is available, which allows the assembly of the highly tested Dell'Orto PHBH 26/28/30 carburettors and the related Casa Performance MaxiFlow air filter with dedicated sleeve, without drilling the side hood. The kit is supplied complete with gaskets for assembly.
