CNC'd aluminum case half for Vespa Bravo, Ciao, Grande, Si etc.
Designed to fit up to stock style cases. Will not fit Malossi reed cases or the Polini Evolution cases.
Allows you to run a side reed valve instead of the small rotary port. Polini/Tomos style reed pattern so you can fit all kinds of fun 4 petal reed setups on here.
These are setup to use the larger 46mm kits but you can still run smaller bore cylinders.
