Transmission W5 Vespa PX200 MALOSSI for Cosa- /New Style Clutch: finally it is possible to use a Cosa clutch also with an upgear kit. The kit comes with clutch gear cog for the Cosa with straight teeths from the MALOSSI transmission, the big primary gear cog, rivets, etc. The right stuff for a highly tuned P200 engine requiring a longer gear ratio and also asking for an adequate clutch.
