S-Stage Bore Up Kit 125cc (with Cam) Super Cub 110 (JA44) / Cross Cub (JA45)

The S-Stage Big Bore Kit allows you to increase your engine's displacement to 125cc simply by replacing the cylinder and piston, while retaining the stock cylinder head.
By increasing the stock 110cc engine to 125cc and installing our sports camshaft and FI-CON2 (injection controller), you can improve output performance and achieve a torquey ride.
Furthermore, installing our exhaust system at the same time will further enhance output performance.
Bore Diameter: 53.5mm, Compression Ratio: 10.8:1
When installing the S-Stage Big Bore Kit, simultaneous installation of an FI-CON2 (injection controller) is required.
Always use high-octane gasoline.
