Got a few of these for my vespa ciao they fit really snug. You will have to file or sand them do in order for them to fit perfectly in the keyway of the crankshaft or it will fly out when turning the engine over.

No bevelled edges, this bad boy fills the slots. Ive tried making these, forget that, just buy a few of these and never worry again
