■Product Description
The Hyper S-Stage Bore Up Kit includes the S-Stage Bore Up Kit, FI-CON TYPE-X (injection controller), Big Throttle Body Kit, and a high-capacity injector.

■Detailed Description
●S-Stage Bore Up Kit 145cc
This bore up kit changes the displacement from the stock 124cc to 145cc by replacing the cylinder and piston.
When installed simultaneously with the FI-CON TYPE-X (injection controller), it achieves powerful output characteristics different from the stock setup.
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 SP Takegawa's M5 temperature sensor, allowing cylinder temperature to be measured by purchasing a separate thermometer (Compact LED Thermometer with M5 Temperature Sensor).
*As the displacement will exceed 125cc, it cannot be ridden on public roads under light motorcycle class 2 registration. It is for competition use only.
●Sports Camshaft (N-10)
Optimized profile to maximize 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 stored around the engine and installed without disturbing the vehicle's silhouette.
Furthermore, it can be installed without any modification to the cowl or wiring. An air filter with excellent intake efficiency is included.
*Cannot be used with stock engines.
By adopting a φ34mm big throttle body, it maximizes the performance of SP Takegawa engine parts and enables increased output.
●FI-CON TYPE-X (Injection Controller)
This is an injection controller that can be connected to the genuine ECU with a coupler.
Various MAPs are preset for each engine specification, so basic operations are completed and you can ride by simply selecting the MAP that matches your bore up kit or throttle body specifications on your smartphone or PC.
It offers content that even advanced users can fully enjoy, such as setting adjustments based on existing MAPs or creating new MAPs according to their preferences.
It can be connected to a PC or smartphone while the engine is running, and in addition to a very convenient tachometer screen and throttle opening graph screen for settings, engine temperature can be monitored.
It is equipped with a rev limit function.

■Notes
*The image is for illustration purposes only. It includes products with different sizes and colors.
*Product design and specifications may change without prior notice. Please be aware of this.
*By installing an SP Takegawa bore up kit, engine output and torque will increase significantly, which increases the stress on the crankshaft, such as twisting and deflection. SP Takegawa recommends simultaneously installing a crankshaft support adapter to reduce the load on the crankshaft. The crankshaft support adapter adds support using ball bearings at the flywheel side end of the crankshaft, suppressing twisting and deflection, and improving crankshaft durability.
*This product is made to order, so cancellations after ordering are not possible.
*Due to being made to order, 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.
