【SP Takegawa 01-05-5463 S-Stage α Bore Up Kit 145cc CT125 Hunter Cub Engine Parts Takegawa】
■Product Description
The S-Stage α Bore Up Kit includes the S-Stage Bore Up Kit and an FI-Con TYPE-X (injection controller).

■Detailed Description
●S-Stage Bore Up Kit 145cc (Sports Camshaft included)
This bore up kit increases the displacement from the stock 124cc to 145cc by changing the cylinder and piston.
When installed simultaneously with the FI-Con TYPE-X (injection controller), it achieves a torqueful output characteristic different from the stock.
The cylinder uses an aluminum iron sleeve cylinder.
Bore diameter 54mm. Stroke 63.1mm (stock). Compression ratio 11.2:1.
Since the cylinder allows for the installation of an SP Takegawa M5 temperature sensor, you can measure the cylinder temperature by purchasing a separate thermometer (Compact LED Thermometer with M5 temperature sensor).
*Since the displacement will be 125cc or more, it is not possible to ride on public roads with a Class 2 moped registration. This is for competition use only.
●Sports Camshaft (N-10)
The optimal profile maximizes the performance of the stock cylinder head, improving output performance. When installed on a stock engine, it improves output in the high RPM range.
By removing the decompression parts from the stock camshaft and installing them on the sports camshaft, it becomes an auto decompression specification.
●FI-Con TYPE-X (Injection Controller)
This injection controller can be connected to the genuine ECU with a coupler.
It comes pre-set with various MAPs tailored to each engine specification, so basic operation is complete and ready to run simply by selecting the MAP that matches your bore up kit or throttle body specifications on your smartphone or PC.
It offers enough enjoyment for advanced users, allowing them to adjust settings based on existing MAPs or create new MAPs to their liking.
It can connect to a PC or smartphone while the engine is running, and in addition to convenient tachometer and throttle opening graph screens for tuning, it allows for monitoring of engine temperature.
It is equipped with a rev limit function.

■Notes
*Images are for illustration purposes only. Includes products with different sizes and colors.
*Product designs and specifications may change without prior notice. Please understand.
*Due to the significant increase in engine output and torque with the installation of SP Takegawa bore up kits, the crankshaft is subjected to increased stress such as twisting and deflection. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the load on the crankshaft. The crankshaft support adapter adds support with a ball bearing to the flywheel side end of the crankshaft, suppressing twisting and deflection, and improving crankshaft durability.
*Since this product is made-to-order, cancellations after ordering are not possible.
*This is a made-to-order product, so it may take several days for delivery. Also, please note that the manufacturer may discontinue the product or change specifications without prior notice.
