S-Stage Bore Up Kit 125cc (Camshaft Not Included) Super Cub 110 (JA44) / Cross Cub (JA45)

The S-Stage Big Bore Kit allows you to convert your engine to 125cc simply by replacing the cylinder and piston, while retaining the stock cylinder head.
By changing from the stock 110cc engine to 125cc and installing our sports camshaft and FI Con 2 (injection controller), you can improve power output and achieve powerful acceleration.
Additionally, by simultaneously installing our exhaust system, power output will be further enhanced.
Bore diameter: 53.5mm, Compression ratio: 10.8:1
When installing the S-Stage Big Bore Kit, simultaneous installation of the FI Con 2 (injection controller) is required.
Always use high-octane gasoline.
The "without sports camshaft" option is for those who already have only a camshaft installed.
