S-Stage α Bore-Up Kit 145cc

【Takegawa 01-05-5476 S-Stage α Bore Up Kit 145cc GROM Motorcycle Injection Controller TAKEGAWA】
■Product Description
The S-Stage α Bore Up Kit includes the S-Stage Bore Up Kit, FI Con TYPE-X (injection controller), and a large-capacity injector.

【S-Stage Bore Up Kit 145cc (Sports Camshaft Included)】
This bore-up kit allows you to change 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 a torqueful output characteristic different from stock.
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 a 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 moped license (Class 2). It 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 assembling them onto the sports camshaft, it becomes an auto decompression specification.
Optional part: N-20 Camshaft - You can enjoy improved driving performance by replacing it according to your intended use.

【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 operations and start driving by simply selecting the map that matches your bore-up kit or throttle body specifications on your smartphone or computer. It also offers advanced features such as customizing existing maps or creating new ones, which will be fully enjoyable for experienced users. When connected to a computer or smartphone with the engine running, it allows for convenient setting adjustments, including a tachometer screen, throttle opening graph screen, and engine temperature monitoring. It also includes a rev limit function.
Can be installed simultaneously with the Honda genuine immobilizer alarm.
To use the FI Con TYPE-X, a compatible computer or smartphone is required. It cannot be used if these requirements are not met. Also, an internet connection is required to download the software or app.
Please note that the app is paid.

■Precautions
※The installation of an SP Takegawa bore-up kit significantly increases engine output and torque, which places increased stress such as twisting and deflection on the crankshaft. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the load on the crankshaft. The crankshaft support adapter enhances crankshaft durability by adding ball bearing support to the flywheel end of the crankshaft, suppressing twisting and deflection.
※Since the displacement will be 125cc or more, it is not possible to ride on public roads with a moped license (Class 2). It is for competition use only.
