What protection does an EP motorcycle radiator & header guard set give?

An EP radiator guard protects the Aprilia RS660 radiator from damage while allowing cooling air to pass through - and look good at the same time. A radiator's delicate cooling fins easily bend, and misaligned fins can cause overheating. The radiator's internal cores can also be holed by stones, etc; all usually picked up and flung directly into the radiator from the bike's front tyre or from other traffic. Leaking coolant will make the motorbike inoperable because of overheating, which can result in engine damage.
