I picked up an '06 WR450 this spring and have made it street legal. The previous owner had already installed a YZ fender. I installed a tail/brake light and a Moose tool kit on the fender. I don't remember the brand name of the tail light but I picked it out because it fit nicely and was one of the lightest I could find. The dealer where I bought it in Denver had a Baja Designs and it was significantly heavier than the one I choose. My tool kit is probably carrying more than I need but I have always liked tools on the road and in the woods. I am not pushing the bike too hard but the fender flexed enough a couple of times that the license plate snagged the tire and bent under. Before I installed the light kit and tool bag the fender already had some white stress marks where it had probably bent under at some point in the past. It was also missing a couple of mounting bolts that I have already replaced. So maybe the fender was in sub-par condition before my modifications. Anyone else with a dual sport conversion run into this problem? Anyone have a suggestion about bracing the fender or who makes the strongest replacement fender so I can try to fix this problem? I don't think the weight of the light kit is excessive and I really don't want to pull any more tools out of the rear fender bag if I can avoid it. I already have a Moose front fender bag carrying a spare tube and a couple of parts. Thanks for your help.
