Description
S-stage Alpha Big Bore Kit includes S-stage Big Bore Kit, FI-CON TYPE-e (Injection Controller) and Spark Plug.
■S Stage Big Bore Kit 181cc
This is a big bore kit which can change the displacement from stock 124cc to 181cc by changing the cylinder and piston.
By installing the FI-CON TYPE-e (Injection Controller) at the same time, you can achieve a torquey output characteristic that is different from stock.
The cylinder is an all aluminum ceramic cylinder with excellent durability, airtightness and heat dissipation.
The cylinder is equipped with an oil extraction boss to the oil cooler.
An M5 temperature sensor can be mounted on the oil plug bolt.
By using SP Takegawa's compact LED thermometer set with M5 temperature sensor, cylinder temperature can be measured.
■Sports Camshaft (N-20)
This is the best profile to maximize the performance of the stock cylinder head and improve the output performance.
By installing it on the stock engine, the power output in the high RPM range will be improved.
For the sports camshaft (N-20), remove the decompression parts from the stock camshaft and assemble it to the sports camshaft for auto decompression.
■FI Controller TYPE-e (Injection Controller)
The fuel injection time needs to be corrected by the FI controller because the ideal A / F ratio will be deviated by installing the sports camshaft and exhaust parts.
FI-CON TYPE-e is equipped with multiple data set up by SP Takekawa for SP Takekawa engine parts, so you can easily select, change and modify the setting data by PC or smart phone according to your engine specification.
The injection time can be adjusted up to 5000μs (maximum) and down to 7500μs (maximum), so it can be used for a wide range of vehicles from stock displacement to those with increased bore.
The monitoring function of engine speed, engine temperature, throttle opening degree, and injector opening / closing ratio by PC or smart phone is equipped, so it is very convenient to use it for setting.
It can be used with all SP Takegawa products (for CT125) from stock displacement to big bore kit.
・Coupler-on installation to stock ECU!!!
Because the coupler that corresponds to the stock ECU is adopted for the wiring of the controller, there is no need to modify the wiring at all, and it can be installed by coupler-on to the stock ECU.

Caution
*Not compatible with JA65 (2023) model.*Installation of S-stage big bore kit
・By installing the S-stage Big Bore Kit by SP Takekawa, the engine power and torque will be greatly increased and the crankshaft will be subjected to more torsion and deflection.
・We recommend you to install the crankshaft support adapter to reduce the load on the crankshaft.
・The Crankshaft Support Adaptor adds ball bearing support to the end of the flywheel side of the crankshaft to reduce twisting and deflection and to increase the durability of the crankshaft.(Part Number: crankshaft support adapter for ct125 (ja55) 01-10-0145)
*When using FI-CON TYPE-e, a computer or smartphone that meets the requirements is required.If you do not meet the requirements, you will not be able to use this product.You will also need to be connected to the Internet to download software and applications.In the case of an application, a fee is charged.
*Depending on the lot, the product may be delivered with the old price and label with the old JAN code before the price change.
