The S-Stage big bore kit allows you to increase the displacement to 81cc simply by replacing the cylinder and piston, while keeping the stock cylinder head.
By changing the stock 50cc engine to 81cc and installing Takegawa's sport camshaft and FI CON2 (injection controller), you can improve power output and achieve powerful acceleration.
Furthermore, installing a Takegawa exhaust simultaneously will further enhance power output.
