Cast piston adopted.\n\u003cbr\u003eBore diameter 56mm. Compression ratio 11.2:1. Stroke 57.9mm (normal).\n\u003cbr\u003e●Sports Camshaft (N-15) Decompression Specification\n\u003cbr\u003eThe Sports Camshaft (N-15) is a camshaft developed for entry-level models. It improves output performance by optimizing the profile to bring out the full potential of the normal cylinder head.\n\u003cbr\u003eWhen installed, the Sports Camshaft (N-15) will be a decompression specification.\n\u003cbr\u003eGenuine decompression parts cannot be assembled with the N-15.\n\u003cbr\u003e●FI-Con TYPE-e (Injection Controller)\n\u003cbr\u003eWhen installing a sports camshaft or muffler parts, the air-fuel ratio can deviate significantly from ideal, so it is necessary to correct the fuel injection time with the FI-Con.\n\u003cbr\u003eThe FI-Con TYPE-e has multiple setting data pre-installed by SP Takegawa for SP Takegawa engine parts, so you can easily select, change, and modify setting data using a computer or smartphone according to your engine specifications.\n\u003cbr\u003eThe injection time adjustment ranges from a maximum increase of 5000μs to a maximum decrease of 7500μs, making it suitable for a wide range of vehicles from normal displacement to bore up vehicles.\n\u003cbr\u003eIt also features monitoring functions for engine speed, engine temperature, throttle opening, and injector opening\/closing rate using a computer or smartphone, which is very convenient for setting.\n\u003cbr\u003eIt can be used with all SP Takegawa products (for CT125) from normal displacement to bore up kits.\n\u003cbr\u003e●Connects to genuine ECU with coupler\n\u003cbr\u003eSince the controller wiring uses a coupler compatible with the genuine ECU, no wiring modification is required, and it can be installed by simply connecting the coupler to the genuine ECU.\n\u003cbr\u003e●Big Throttle Body Kit φ28\n\u003cbr\u003eThis product is an original SP Takegawa big throttle body kit compatible with the normal air cleaner box\/connecting tube.\n\u003cbr\u003eCompared to the genuine throttle body of φ24mm, the SP Takegawa big throttle body is φ28mm.\n\u003cbr\u003eBy adopting the SP Takegawa big throttle body and manifold, it can be connected to the normal connecting tube, so the normal air cleaner box can be used as is.\n\u003cbr\u003eNo modification to the cowl or wiring is required; by simply replacing the normal throttle body on the genuine vehicle, the performance of the normal cylinder head can be maximized, and output can be increased. \u003c\/p\u003e\n\n\u003cp\u003e■Compatible Models\n\u003cbr\u003eHONDA\n\u003cbr\u003eCT125 (JA55-1000001～)\u003c\/p\u003e\n\n\u003cp\u003e■Notes\n\u003cbr\u003e*The image is for illustration purposes only. It includes products with different sizes and colors.\n\u003cbr\u003e*Product design and specifications are subject to change without notice. Please understand.\n\u003cbr\u003e*Due to the significant increase in engine output and torque when installing the SP Takegawa e-stage bore up kit, the crankshaft is subjected to increased stress such as twisting and deflection. SP Takegawa recommends simultaneously installing a crankshaft support adapter to reduce the load on the crankshaft.\n\u003cbr\u003eThe crankshaft support adapter enhances crankshaft durability by adding support with a ball bearing at the end of the crankshaft flywheel side, thereby suppressing twisting and deflection.\n\u003cbr\u003e*This product is made to order, so cancellations after ordering are not possible.\n\u003cbr\u003e*As this product is made to order, it takes time for delivery. Also, please note that the manufacturer may discontinue or change specifications without notice.
