【SP武川 01-05-5475 Hyper S-Stage Bore Up Kit 145cc CT125 Hunter Cub Engine Parts Takegawa】
■Product Description
The Hyper S-Stage Bore Up Kit includes the S-Stage Bore Up Kit, FI-CON TYPE-X (injection controller), and a Big Throttle Body Kit.

■Detailed Description
●S-Stage Bore Up Kit 145cc
This bore up kit changes 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 can be fitted with an SP Takegawa M5 temperature sensor, so by purchasing a separate thermometer (compact LED thermometer with M5 temperature sensor), you can measure the cylinder temperature.
*Since the displacement will be 125cc or more, it cannot be ridden on public roads under light motorcycle class 2 registration. It is for competition use only.
●Sport 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 installing them on the sport camshaft, it becomes an auto decompression specification.
●Big Throttle Body Kit φ28 (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 stored around the engine and installed without disrupting the vehicle's silhouette.
Furthermore, it can be installed without any modification to the cowl or wiring.
●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-set with various MAPs for each engine specification, so simply select the MAP that matches your bore up kit or throttle body specifications on your smartphone or PC to complete basic operations and enable driving.
The content is sufficiently enjoyable for advanced users, allowing them to adjust settings based on existing MAPs or create new MAPs to their liking.
It can connect to a PC or smartphone when the engine is running, and in addition to the tachometer screen and throttle opening graph screen, which are very convenient for setting, it can also monitor engine temperature.
It is equipped with a rev limit function.

■Notes
*Images are for illustration purposes only. Includes items of different sizes and colors.
*Product design and specifications may change without notice. Please be aware of this.
*By installing SP Takegawa bore up kits, engine output and torque are significantly increased, leading to increased stress such as twisting and deflection on the crankshaft. SP Takegawa recommends simultaneously installing a crankshaft support adapter to reduce the load on the crankshaft. The crankshaft support adapter enhances crankshaft durability by adding support from a ball bearing at the flywheel end of the crankshaft, suppressing twisting and deflection.
*This product is made to order, so cancellations are not possible after ordering.
*Due to being made to order, it is a product that takes time for delivery. Also, without prior notice, the manufacturer may discontinue the product or change its specifications. Please be aware of this in advance.
