The EP radiator guard protects the Suzuki GSX1300R radiator from damage caused by road debris (stones, mud, dropped waste etc) while at the same time allowing cool air to pass through. The radiator's thin, soft aluminium cooling fins easily bend, and bent fins can restrict cooling air, which can lead to overheating. The radiator's internal cores are also prone to being holed by stones that can be picked up by the front tyre and flung directly into the radiator. Leaking coolant can make the GSX1300R inoperable because of overheating, which, in turn, can quickly lead to engine damage.
