【SP Takegawa 01-05-5467 Hyper S-Stage Big Bore Kit 145cc Dax 125 Engine Parts Takegawa】
■Product Description
The Hyper S-Stage Big Bore Kit includes the S-Stage Big Bore Kit, FI-CON TYPE-X (injection controller), big throttle body kit, and a large-capacity injector.

■Detailed Description
●S-Stage Big Bore Kit 145cc
This big bore kit changes the displacement from the stock 124cc to 145cc by replacing the cylinder and piston.
By installing it simultaneously with the FI-CON TYPE-X (injection controller), it achieves powerful output characteristics that differ from the stock engine.
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, allowing you to 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 light motorcycle (Type 2) registration. It is for competition 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 RPM range.
By removing the decompression parts from the stock camshaft and installing them on the sports camshaft, it becomes an auto-decompression specification.
●Big Throttle Body Kit φ34 (for stock cylinder head)
This product is an original SP Takegawa big throttle body kit developed for SP Takegawa engine parts.
It can be compactly housed around the engine without altering the vehicle's silhouette.
Furthermore, no modification of the cowl or wiring is required for installation. It includes an air filter with excellent intake efficiency.
*Cannot be used with stock engines.
By adopting a φ34mm big throttle body, it maximizes the performance of SP Takegawa engine parts and increases output.
●FI-CON TYPE-X (Injection Controller)
This is an injection controller that can be connected to the genuine ECU with a coupler.
It comes pre-loaded with various MAPs for each engine specification, so you can select the MAP that matches your big bore kit or throttle body specifications using your smartphone or PC, and the basic operation will be complete and you can start riding.
It allows advanced users to enjoy customizing settings based on existing MAPs or creating new MAPs.
It can be connected to a PC or smartphone while the engine is running, making settings very convenient. In addition to the tachometer screen and throttle opening graph screen, engine temperature monitoring is also possible.
It is equipped with a rev limit function.

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