I picked up a polycarbonate shark fin from Wes Woodin after seeing it in the carbon fiber vs aluminum glide plate thread. http://www.thumpertalk.com/forum/showthread.php?p=3388574#post3388574 Fit/Finish are great. It's even notched out where there are zip ties around the frame rails, and allows for unimpeded routing of the radiator overflow. Overall I'm very impressed. I haven't had a chance to try it out at the track yet, but it'll definitely be better than what yamaha included for protection Thanks Wes!
