The great thing about only riding when its nice out is you can rip off fenders like this without any guilt. I only ride in the rain when I get caught it in by no intention of mine, rare situation.Rip that fender off of there and replace it with a custom one make a modification to make an excuse for another modification
Here's a better photo. It's the rearview mirror.(snip) Looks like they added some kind of gauge too. There's something silver (reminiscent of a meat thermometer) sticking out from the front windshield.
