【SP武川 01-05-5462 S-Stage α Bore Up Kit 145cc Monkey 125 Engine Parts 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.

■Detailed Description
●S-Stage Bore Up Kit 145cc (Sports Camshaft included)
This bore up kit allows you to change the displacement from the normal 124cc to 145cc by replacing the cylinder and piston.
By installing it 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.
The cylinder is compatible with SP Takegawa's M5 temperature sensor, so 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 the moped class 2 registration. 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-revolution range.
By removing the decompression parts from the stock camshaft and assembling them into 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 each engine specification, so basic operation is completed and you can start riding by simply selecting the MAP that matches your bore up kit or throttle body specifications on your smartphone or PC.
Even advanced users can fully enjoy it, with the ability to set up or create new MAPs based on existing MAPs.
It can be connected to a PC or smartphone while the engine is running, and in addition to convenient tachometer and throttle opening graph screens for setup, it can also monitor engine temperature.
It is equipped with rev limit and pit lane limiter functions.

■Compatible Models

*Cannot be installed on the Monkey 125 Thai model (MLHJB03).

■Notes
*The image is for illustration purposes only. It includes products with different sizes and colors.
*Product design and specifications may change without prior notice. Please be aware of this.
*Due to the significant increase in engine output and torque with the installation of SP Takegawa's bore up kit, the crankshaft will be 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 at the flywheel end of the crankshaft, suppressing twisting and deflection, and improving the durability of the crankshaft.
*This product is made to order, so cancellations after ordering are not possible.
*As this product is made to order, it may take some time for delivery. Also, the manufacturer may discontinue or change specifications without prior notice. Please be aware of this.
