Complete cylinder kit exclusively produced for Casa Lambretta. Finally there is an option available to give the 50 cc Lambretta engines a reasonable power boost. Thanks to the nikasil plating the cylinder capacity is increased by 50%. The porting layout is similar to the genuine 75 cc cylinder of the LUI model. The item includes: cylinder, 47 mm piston kit, cylinder head and gaskets, small parts.
This cylinder is perfectly combinable with the carburettor kits by Casa Lambretta which are available for the LUI and Junior models.
In any case, it is necessary to adapt the gear ratio in order to actually get the boosted power For this purpose Casa Lambretta offers front sprockets with 13 or 15 teeth. If you have a LUI then you need a 13-tooth sprocket. Depending on the model, for J50 there are genuine front sprockets with 11 or 13 teeth. If your Lambretta has a 11-tooth sprocket, then you have to replace it with a 13-tooth sprocket, while if it has a 13-tooth sprocket, this shall be replaced with a 15-tooth sprocket.
