This radiator uses a high-efficiency core featuring a 1.25-inch-wide tube design to give maximum tube-to-fin contact for optimum efficiency. The 14-fins-per-inch design maximizes airflow to transfer heat and allow dirt and debris to pass easily through the radiator. The radiator features a double-pass configuration, meaning that fluid passes over the top half of the radiator then the bottom half, allowing heat to dissipate quickly. The stock mounting dimensions of the original TRX250R are an easy retrofit to the original chassis or aftermarket frames. The retail price is $219.
