Eerily similar to another famous Vespa kit. Two very large top ports, cast iron, and 43mm.
No case boring necessary for this kit, just a good case match for the transfers.
Will fit all vespa moped models and kinetic with a 10mm wrist pin. If you're not sure, you will have to remove your cylinder and measure your existing one! You could also just install the matching athena 10 pin crankshaft at the same time as this kit.
Comes with piston, rings, pin/clips, cylinder, and base gasket.
