■Product Description
The e-stage α bore up kit includes the e-stage bore up kit, FI-CON TYPE-e (injection controller), and spark plugs.

■Detailed Description
● e-stage Bore Up Kit 143cc
This bore up kit changes the displacement from the normal 124cc to 143cc by replacing the cylinder and piston.
When installed simultaneously with the FI-CON TYPE-e (injection controller), it achieves powerful output characteristics unlike the stock model.
The cylinder uses the same steel cylinder as the stock model.
Black painted. Cast piston adopted.
Bore diameter 56mm. Compression ratio 11.2:1. Stroke 57.9mm (stock).
●Sports Camshaft (N-15) Decompression Specification
The Sports Camshaft (N-15) is a camshaft developed for entry-level models. It improves output performance with an optimal profile that brings out the performance of the stock cylinder head.
The Sports Camshaft (N-15) will be a decompression specification when installed.
Genuine decompression parts cannot be assembled with the N-15.
●FI-CON TYPE-e (Injection Controller)
When installing sports camshafts or exhaust parts, the air-fuel ratio deviates significantly from the ideal, so it is necessary to correct the fuel injection time with the FI-CON.
The FI-CON TYPE-e has multiple data sets pre-configured by SP Takegawa to match SP Takegawa engine parts, so you can easily select, change, and correct setting data using a PC or smartphone according to your engine specifications.
The injection time can be adjusted by up to 5000μs for enrichment and up to 7500μs for reduction, making it widely applicable from stock displacement to bore up vehicles.
It features monitoring functions for engine speed, engine temperature, throttle opening, and injector opening/closing rate using a PC or smartphone, which is very convenient for setting adjustments.
It can be used with all SP Takegawa products (for CT125) from stock displacement to bore up kits.
●Can be installed by simply plugging into the genuine ECU.
Since the controller wiring uses a coupler compatible with the genuine ECU, no wiring processing is required, and it can be installed by simply plugging into the genuine ECU.

■Notes
※The image is for illustration purposes only. It includes products with different sizes and colors.
※Product design and specifications are subject to change without notice. Please understand.
※Due to the significant increase in engine output and torque with the installation of SP Takegawa's e-stage bore up kit, the crankshaft will experience increased stress such as twisting and deflection. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the burden on the crankshaft.
The crankshaft support adapter enhances crankshaft durability by suppressing twisting and deflection through the addition of ball bearing support at the end of the crankshaft's flywheel side.
※This product is made to order, so cancellations after ordering are not possible.
※As this is a made-to-order product, it may take some time for delivery. Also, please note that the manufacturer may discontinue the product or change its specifications without prior notice. Thank you for your understanding.
