1. like a shock absorber for debris headed for your radiator
It's kind of thin, white, and flimsy looking at first, but then you realize it has foam pads that rest between the guard and your radiator fins. So I'm assuming it acts like a shock absorber for any foreign object headed for your radiator. I just installed it, and haven't had a chance to ride with it installed, it fits exactly as described, but it just seems kind of flimsy 4 the money you have to pay. I guess if it saves a blown radiator or damaged engine than its cheap insurance
