The compression ratio of a conventional S-stage is 11.5: 1 and recommended high octane gasoline, but the S-stage eco has a compression ratio of 10.5: 1 to allow the use of regular gasoline. An all aluminum ceramic cylinder with excellent durability, airtightness and heat dissipation, special pistons and a camshaft that brings out the best performance of the cylinder head are included. The optimum piston design minimizes the loss of power from high-octane gasoline only, resulting in a significant increase in power throughout the entire range from low to high RPM. The temperature sensor can be installed on the cylinder, so that the temperature change of the cylinder can be checked by installing SP Takegawa's compact LCD thermometer (M5 temperature sensor) or super multi LCD meter.
S-stage Eco Big Bore Kit 161cc with FI CON (Injection Controller) for fuel volume correction. If your bike has a completely stock engine, this product with FI CON is recommended.
This all-in-one package includes the S-stage eco big bore kit (161cc), FI CON (fuel volume correction) and the drivetrain setting parts "High Speed Pulley & Torque Cam Kit". The high speed pulley increases the maximum speed while maintaining a stable output for the engine with big bore, and the torque cam prevents a drop in rotation during gear shifting and allows the output to be transmitted fully.
