Athena's Big Bore Kit for 50cc Yamaha Zuma and Vino features a cast aluminum cylinder with a nickel carbide plated bore. All Athena kits come with a cylinder, cylinder head, piston assembly (piston, rings, wrist pin, and circlips) carbon reeds and all top end gaskets necessary for installation. Replacement piston kits and top end gaskets are available separately. Fits the horizontal 2T air cooled engine found in both Zuma and Vino scooters.

The advantage of the aluminum cylinder is that it dissipates heat a lot faster than a cast iron cylinder which allows you to run higher compression which in turn give a significant increase in horse power. The aluminum head also makes it very easy to port and polish.
