Compact Cool Kit 3-Fin Oil Cooler

The SP Takegawa Compact Cool Kit provides critical thermal management for the Honda Super Cub C125 (JA48) when upgraded with the S-stage 181cc bore up kit. By mounting a 3-fin, 4-oil-line cooler under the engine, this kit effectively suppresses the oil temperature increases associated with high-displacement engine modifications. The system utilizes an oil takeoff boss located on the S-stage 181cc cylinder to circulate oil through the cooler, which comes equipped with protective plates and guards as standard. Installation requires the cooler to be secured via a bracket attached beneath the cylinder head. Please note strict compatibility requirements: this kit is designed exclusively for vehicles equipped with the SP Takegawa S-stage bore up kit 181cc and does not fit engines with stock or e-stage cylinders. Furthermore, the installation requires an aftermarket exhaust; it is not compatible with the stock exhaust system. An additional 40cc of oil is required beyond the standard capacity during installation.
