Perfect for

This is the spare part needed by anyone opening the engine's flywheel side: workshops replacing the flywheel, oil filter, or cover gasket, and enthusiasts performing DIY maintenance on a Vespa Primavera, Sprint, or 946, a Liberty, or a Fly. It's inexpensive, but it's the part that determines whether the engine stays dry: changing it every time the cover is removed avoids having to reopen everything due to an oil leak.
