Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 150 EXC TPI features newly designed radiators which are mounted 12 mm lower than the predecessors. This lowers the center of gravity and matches the design of the new shrouds perfectly, in order to achieve perfect ergonomics. By using CFD technology (computational fluid dynamics) together with a clever coolant circuit routing, the innovative system ensures the optimum engine temperature for the highest performance, no matter what the conditions. Above all, a reworked delta distributor, integrated into the frame triangle, features a 4 mm larger center tube, increasing the cross section by 57%, making the coolant flow from the cylinder head to the radiators more efficient. The radiators also feature special protectors that don’t only serve as protection from flying rocks and debris but also as a brace that disperses energy around the radiators in the event of an impact.
