Honda did make some brush guards, but, they were sort of light duty. The big aftermarket company that made brush guards was Chesapeake Metal Products. Their stuff was really Heavy Duty. I had a set on a KLT110 that I once had and it was really tricked out nice. The price may seem a little high, but really nice stuff is getting harder to come by.
