Athena 43mm "65cc" cylinder kit for Vespa mopeds- Ciao, Bravo, Grande, Si, etc as well as Kinetic TFR and Magnum.
Large transfers, four boost ports, and two auxiliary exhaust ports. Should be a real screamer. 2 rings piston. Aluminum with nikasil plating.
Comes with cylinder, piston, rings, pin/clips, and gasket set.
This is for the 12mm wrist pin engines!! If you have a U.S.A. model bike with original crank- odds are this is what you need. Please check before ordering. Vespa made it easy with three cylinder studs instead of four. That's one less nut to loosen!
