The last time I road my '05 FSE I bit the dust 3 0r 4 really good ones. The third one I hit the front brake in some loose shale on a steep slope and did a superman over the bars and the bike landed on top of my heel and tore ligiments and tendons on top of foot and the arch itself. The fourth one I tumbled into a ravine and landed away from the bike. Since then, I've been riding my road bike and easier trails and forest roads.
So that day the bike and Force Rad Guards got a good workout. No damage! They fit really well and go on easy. They are tuff. Red or black. Get the new ones I mentioned. Take a look at GMP's Flatland Guard extra bracing he made. They would then be completely bullet proof.
