■Product Description
The S-Stage Alpha Bore Up Kit includes the S-Stage Bore Up Kit, FI-CON TYPE-X (injection controller), and a large capacity injector.

■Detailed Description
●S-Stage Bore Up Kit 145cc (with Sports Camshaft)
This bore up kit changes the displacement from the stock 124cc to 145cc by replacing the cylinder and piston.
When installed simultaneously with the FI-CON TYPE-X (injection controller), it achieves powerful output characteristics unlike the stock engine.
The cylinder uses an aluminum iron sleeve cylinder.
Bore diameter 54mm. Stroke 63.1mm (stock). Compression ratio 11.2:1.
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).
*Since the displacement will be 125cc or more, it cannot be ridden on public roads under light motorcycle class 2 registration. It is for competition use only.
●Sports Camshaft (N-10)
Output performance is improved by an optimal profile that maximizes the performance of the stock cylinder head.
When installed on a stock engine, output in the high RPM range is improved.
By removing the decomp 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 is an injection controller that can be connected to the genuine ECU with a coupler.
It comes with preset maps for various engine specifications, so you can complete basic operation and start riding by simply selecting the map that matches your bore up kit or throttle body specifications on your smartphone or computer.
It also allows advanced users to enjoy customizing settings based on existing maps or creating new maps.
You can connect to a computer or smartphone while the engine is running, and in addition to the very convenient tachometer screen and throttle opening graph screen, you can also monitor engine temperature.
It is equipped with rev limit and pit lane limiter functions.

■Notes
*The image is for illustration purposes only. It includes products of different sizes and colors.
*Product designs and specifications are subject to change without notice. Please be aware.
*When an SP Takegawa bore up kit is installed, engine output and torque are significantly increased, which increases stress such as twisting and deflection on the crankshaft. SP Takegawa recommends simultaneously installing a crankshaft support adapter to reduce the load on the crankshaft. The crankshaft support adapter enhances crankshaft durability by adding ball bearing support to the flywheel side end of the crankshaft, thereby suppressing twisting and deflection.
