S-Stage Bore Up Kit (C-Type) for 12V Monkey, Gorilla, Baja, Jazz 88cc

The S-Stage allows for increased displacement while retaining the stock cylinder head and crankshaft.
Furthermore, the S-Stage 88cc is available in two types: "Standard" for high-octane gasoline and "eco" for regular gasoline.
While the conventional Standard type had a compression ratio of 11.5:1 and recommended high-octane gasoline, the S-Stage eco has a compression ratio of 10.5:1, making it possible to use regular gasoline.
This can reduce fuel costs.
