【SP Takegawa 01-05-5468 S-Stage Bore Up Kit 145cc with N-10 Cam for Super Cub 110 / Cross Cub 110 Engine Parts】
■Product Description
Enjoy powerful output performance not found in the stock engine.

■Detailed Description
●S-Stage Bore Up Kit 145cc
By changing the cylinder and piston, the displacement can be changed from the stock 110cc to 145cc.
When installed simultaneously 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.
The cylinder can be fitted with an SP Takegawa M5 temperature sensor, so by purchasing a separate thermometer (Compact LED Thermometer with M5 Temperature Sensor), you can measure the cylinder temperature.
The S-Stage Bore Up Kit comes in two types: one without a sports camshaft and one with.
●Sports Camshaft (N-10)
Optimal profiles maximize the performance of the stock cylinder head, improving output. When installed on a stock engine, it improves output in the high-rpm range.
By removing the decomp parts from the stock camshaft and installing them on the sports camshaft, it becomes an auto-decompression specification.

■Precautions
*Image is for illustration purposes. Includes products of 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. This kit is for competition use only.
*Due to the significant increase in engine output and torque with the SP Takegawa bore up kit, stress such as twisting and deflection on the crankshaft will increase. SP Takegawa recommends simultaneous installation of a crankshaft support adapter to reduce the load on the crankshaft. The crankshaft support adapter enhances the durability of the crankshaft by adding ball bearing support to the end of the flywheel side of the crankshaft, suppressing twisting and deflection.
