Maintaining the optimal engine temperature and consistent horsepower throughout the ride. The KTM 500 EXC-F features newly designed radiators which are mounted 12 mm lower than the predecessors, lowering the center of gravity, matching the design of the new shrouds perfectly and providing perfect ergonomics. By using CFD technology (Computational Fluid Dynamics) and a smarter coolant circuit routing, the innovative system ensures optimum engine temperature for the highest performance, in all conditions. Above all, a reworked delta distributor, integrated into the frame triangle has a 4 mm larger center tube, increasing the cross section by 57%, so coolant flows from the cylinder head to the radiators more efficiently. This is further aided with the help of a radiator fan as standard. The radiators have special protectors that protect from flying rocks and debris while also acting as a brace to disperse energy around the radiators in the event of an impact.
