Bore Diameter: 53.5mm / Compression ratio 12.5:1 [Components] Big throttle body
*FI-controller (injection controller) must be installed at the same time when S-stage big bore kit is installed.*Always use high-octane gasoline as fuel. *There is no rev limiter cut function in FI-CON.*If you install it on a stock bike, it will not improve performance. *The FI-CON has been tested only on bikes officially sold in Japan.We have not confirmed the compatibility with non-Japanese vehicles. *Please do not install any aftermarket H.I.D kit or any other company's LED headlights or fog lamps at the same time.Some ballasts / inverters (voltage conversion devices) emit high-voltage noise that adversely affects digital circuits, causing product failure or malfunction. *Please do not install the headlight ON / OFF switch and the aftermarket ignition system at the same time. *When installed with SP Takegawa's exhaust, the FI controller (injection controller) must be installed at the same time. *Depending on the lot, the product may be delivered with the old price and label with the old JAN code before the price change.
■S Stage Big Bore Kit The S-stage Big Bore Kit allows you to use the stock cylinder head as is, and simply replace the cylinder and piston to make it 125cc. The engine has been changed from a stock 110cc engine to a 125cc engine and equipped with SP Takegawa sports camshafts and FI CON 2 (injection controller) to improve output performance and deliver a torquey ride. By installing SP Takegawa's exhaust at the same time, the output performance will be further improved. ■Sports Camshaft 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. ・If you install only sports camshaft with stock piston and stock exhaust, injection controller is not necessary. ■FI-CON (injection controller) When SP Takegawa engine parts are installed on an injected car, the fuel mixture will be out of tune.By installing this controller at the same time, the fuel injection amount is corrected by a 16-bit microcomputer inside the injection controller, which determines the engine condition of the installed vehicle and processes calculations in real time based on the signals output from the stock computer. SP Takegawa's Inje The fuel injection controller is capable of injecting more fuel than the maximum injection rate of the stock computer. ■Big Throttle Body Kit (The stock air cleaner box can be used without modification.) It maximizes the performance of the stock cylinder head and achieves high output.You can enjoy the engine characteristic which turns without stress to the high RPM range.
