S-Stage α Bore Up Kit 145cc

【Takegawa 01-05-5489 S-Stage α Bore Up Kit 145cc CT125 Motorcycle Injection Controller TAKEGAWA】
■Product Description
The S-Stage α Bore Up Kit includes the S-Stage Bore Up Kit, a large-capacity injector (G-6), and an FI-CON TYPE-X (injection controller).

【S-Stage Bore Up Kit 145cc (with Sports Camshaft)】
This bore-up kit allows you to increase the displacement from the normal 124cc to 145cc by changing the cylinder and piston.
When installed simultaneously with the FI-CON TYPE-X (injection controller), it achieves powerful output characteristics that differ from the stock.
The cylinder uses an aluminum iron sleeve cylinder.
Bore diameter 54mm / Stroke 63.1mm (stock) / Compression ratio 11.2:1
The cylinder can be fitted with an SP Takegawa M5 temperature sensor, so you can measure the cylinder temperature by purchasing a separate thermometer (Compact LED Thermometer with M5 Temperature Sensor).

【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 part from the stock camshaft and installing it on the sports camshaft, it becomes an auto decompression specification.
・Optional Parts
N-20 Camshaft: Enjoy enhanced riding performance by swapping it out according to your usage.
Large-capacity fuel injector (G-6):
This is a large-capacity fuel injector for vehicles equipped with SP Takegawa high-compression pistons and S-Stage bore-up kits.
This product may cause malfunction if installed on vehicles with engine specifications other than those specified.
For CT125 (JA65-1000001～1099999), installing this product on stock vehicles or vehicles equipped with SP Takegawa engine parts will not improve performance.

【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 simply select the map that matches your bore-up kit or throttle body specifications on your smartphone or PC to complete the basic operations and start riding. It is designed to be fully enjoyable for advanced users who want to customize settings based on existing maps or create new maps. You can connect to a PC or smartphone while the engine is running, which is very convenient for setting,
In addition to the tachometer screen and throttle opening graph screen, engine temperature monitoring is now possible. It also features a rev limit function.
It can be installed simultaneously with the Honda genuine immobilizer alarm.
To use the FI-CON TYPE-X, you will need a compatible PC or smartphone. It cannot be used if these conditions are not met. Also, an internet connection is required to download the software and apps.
Please note that the app may be subject to a fee.

■Precautions
*Due to the significant increase in engine output and torque with the installation of the SP Takegawa bore-up kit, the crankshaft will experience increased stress such as twisting and deflection. To reduce the load on the crankshaft, SP Takegawa recommends installing the crankshaft support adapter simultaneously. The crankshaft support adapter enhances the durability of the crankshaft by adding support with a ball bearing at the end of the flywheel side of the crankshaft, thereby suppressing twisting and deflection.
*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.
*Images are for illustration purposes only. Includes products of different sizes and colors.
*Product design and specifications are subject to change without notice. Please understand.
