The EM-09 PRO model complies with the ROK regulation for what regards the ROK DVS and Shifter ROK categories. Compared to the EM-09 model, it differs in its radiator core that features a reduced pitch between the internal tubes, designed to increase cooling performance. The EM-09 PRO radiator guarantees optimal cooling at any time of the year for the ROK DVS, Shifter ROK and KZ categories. For single-gear categories, its use is recommended only in the summer, with high temperatures. The excellent cooling capacity, due to the special radiator core, is further enhanced by the angled water inlet and outlet tanks. This solution increases the surface exposed to the air, and eliminates the formation of pockets of hot water. The special radiator core, is also recessed into the radiator structure, creating a sort of conveyor that increases the airflow at high speeds and improves cooling. A lot of attention was also put to the water outlet fitting design, studied to increase the flow rate and prevent the silicone hose from rubbing against the curbs. The radiator comes fitted with a deflector.
