S-Stage Bore Up Kit 145cc, No Cam, Super Cub 110, Cross Cub 110

SP Takegawa 01-05-5469 S-Stage Bore Up Kit 145cc (Camshaft Not Included) for Super Cub 110/Cross Cub 110 - Engine Parts
■Product Description
Enjoy powerful output performance not found in the stock engine.

■Detailed Description
By changing the cylinder and piston, the displacement can be changed from the stock 110cc to 145cc.
When installed together with the FI-Con TYPE-X (injection controller), it achieves powerful output characteristics different from the stock engine.
The cylinder uses an aluminum iron sleeve cylinder.
Bore diameter 54mm. Stroke 63.1mm (stock). Compression ratio 11.3:1.
Since the cylinder can accommodate an SP Takegawa M5 temperature sensor, you can measure the cylinder temperature by purchasing a separate thermometer (Compact LED Thermometer with M5 Temperature Sensor).
The S-Stage bore up kit is available in two types: one without a sports camshaft and one with a sports camshaft.

■Compatible Models

Super Cub 110 (JA59-1000001~)

■Notes
*Images are for illustration purposes only. Includes products with different sizes and colors.
*Product design and specifications are subject to change without notice. Please be aware.
*When installing the S-Stage bore up kit, simultaneous installation of the FI-Con TYPE-X (injection controller) is required.
*Since the displacement will be 125cc or more, it is not possible to ride on public roads with a Class 2 moped registration. It is for competition use only.
*By installing the SP Takegawa bore up kit, engine output and torque are significantly increased, which increases the stress on the crankshaft, such as twisting and deflection. To reduce the burden on the crankshaft, SP Takegawa recommends the simultaneous installation of a crankshaft support adapter. The crankshaft support adapter adds support to the flywheel side end of the crankshaft with a ball bearing, thereby suppressing twisting and deflection and enhancing crankshaft durability.
