Casa Lambretta cylinder kit for more power on Lui and J50
Complete cylinder kit manufactured exclusively by Casa Lambretta. The Nikasil-coated aluminum cylinder increases the displacement by more than 50 %. The layout of the channels corresponds to an Innocenti prototype with 80 cc for the lui 75.
The scope of delivery of the kit includes: Cylinder, piston kit, head and gaskets and small parts.
The cylinder is the easiest way to help the small Lambrettas with 50 ccm displacement achieve reasonable performance. Useful additions to the cylinder kit are the carburettor kits from Casa Lambretta, which are available for both the LUI and the Junior series.
In any case, it is essential to adapt the gear ratio so that the extra power gained can be converted accordingly. For this purpose, Casa Lambretta offers the front sprocket with 13 and 15 teeth. The 13-tooth sprocket is used on the lui. On the J50, the original front sprocket is available with 11 teeth or 13 teeth. Here you have to upgrade from 11 to 13 and from 13 to 15 teeth.
