Athena 10 pin crankshaft for Vespa and Piaggio mopeds. Drops right in to Ciao, Bravo, Grande, Si, Citta, etc. This crank is both strong and offers a little more intake duration for going fast. Comes with a new needle bearing! For standard engines, not for kickstart or oil-injected models.
10 PIN CRANK!! You need to match the crank to whatever pin size your piston uses.
