I just got a new double bubble windscreen on ebay for aroound $80 shipped. It is the power bronze. It looks good, and I like the "Daytona" signature at the bottom. Also I broke a mirror and had a hard time finding a replacement that wasn't over 100 and none of t he aftermarket mirrors would fit in the holes. What I did was went to Cycle Gear and got aftermarket mirrors($25 a piece) that had a similar base. Sorry I can't remember the brand or have the part numbers, but I do remember they were for a older style GSXR600 bike. I then removed the mirrors from the base, and used the bases from the existing mirrors. I feel I can see more with these mirrors and they sit lower, so when going through traffic, I feel less likely hitting car mirrors.
