I installed both fender extenders a month ago. I finally "had the chance" to ride in some decent rain yesterday on the way home, 10+ miles in the rain. The front one works like all front extenders thou it is longer than others so has more protection. As far as I know Larry's rear extender is the only one out there. Previously after riding in the rain the back of the bike was covered in dirty crap thrown up by the tire, especially the top case and its lock. With the rear extender the back of the bike was wet, of course, but very little evidence of dirt and other road crap on the back. It didn't look any worse than the rest of the bike's upper parts. I'm extremely happy with its performance.
Excellent product, Larry! Thanks!
