【SP武川 01-05-0603 Hyper S-Stage Bore Up Kit 125cc Big Throttle Body Super Cub 110 Cross Cub 110 Engine Parts Takegawa】
■Product Description
Engine parts that allow you to enjoy a different power performance than the stock engine.
Includes a large throttle body.

■Detailed Description
●S-Stage Bore Up Kit
The S-Stage Bore Up Kit allows you to increase the engine displacement to 125cc by simply replacing the cylinder and piston, while keeping the stock cylinder head.
By changing the stock 110cc engine to 125cc and installing the SP Takegawa sport camshaft and FI Con2 (injection controller), the power output is improved, achieving powerful acceleration.
Furthermore, installing an SP Takegawa muffler at the same time will further improve the power output.
Bore diameter: 53.5mm. Compression ratio: 10.8:1.
●Sport Camshaft (N-15/20)
Optimized profile to maximize the performance of the stock cylinder head, improving power output.
●FI Con TYPE-e (Injection Controller)
When installing sport camshafts or muffler parts, the air-fuel ratio can deviate significantly from the ideal, so it is necessary to correct the fuel injection time with the FI Con.
Installation is simple, just disconnect the stock ECU coupler and connect.
The FI Con TYPE-e has multiple pre-set data settings by SP Takegawa for SP Takegawa engine parts, allowing you to easily select, change, and modify setting data using a computer or smartphone to match your engine specifications.
The injection time adjustment range is a maximum increase of 5000μs and a maximum decrease of 7500μs, making it suitable for a wide range of applications from stock displacement to bore-up vehicles.
It also features monitoring functions for engine speed, engine temperature, throttle opening, and injector opening/closing rate via a computer or smartphone, which is very convenient during tuning.
●Big Throttle Body Kit
Compatible with both bore-up and stock engines, allowing you to enjoy engine characteristics that rev smoothly up to high RPMs without stress.
Since the stock air cleaner box and connecting tube can be used as they are, installation requires no modification.

■Notes
*Images are for illustration purposes only. Includes products of different sizes and colors.
*Product design and specifications are subject to change without notice. Please be aware.
*Due to the significant increase in engine output and torque when installing the SP Takegawa S-Stage Bore Up Kit, the crankshaft experiences 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 supports the flywheel end of the crankshaft with a ball bearing, suppressing twisting and deflection and increasing crankshaft durability.
*This product is made to order, so cancellations after ordering are not possible.
*As this is a made-to-order product, delivery may take some time. Also, please note that the manufacturer may discontinue the product or change specifications without prior notice. Thank you for your understanding.
