After much research and many hours spent reading through the forums I finally decided on the Parabellum windscreen. I'll get right to the point, I ABSOLUTELY LOVE IT.
First let me provide some facts that you may find useful, I'm 60 years old, 6'1" and weigh 250 pounds. My inseam is 30" when I buy jeans. I ride with my stock seat (next thing to be replaced) in the lowest position and my windscreen in the highest setting. My main complaint with the stock windscreen was the "cockpit noise" it created. I found it to be totally unacceptable. I actually thought the stock screen provided adequet wind protection.
I found Parabellum's customer service to be excellent. I ended up getting the "Tall" (26") windscreen. I ordered it via phone Monday afternoon and had it by Thursday morning. That was using their basic shipping. I live in Delaware and they are out of Georgia. Brenda, who I spoke with was fantastic. I purchased the item using 4 gift cards and she was very patient and helpful during the ordering process. Installation was dirt simple. The only thing I believe Parabellum should add to their documentation is to keep the rubber grommets which the bolts pass through on the bike. I was able to determine this by looking at the picture they provided but it should have been noted somewhere.
The hardware Parabellum provides includes 8 "Aztec" washers, 4 large and 4 small. The finish on these is raw aluminum therefore silver and shiny. I strongly recommend spray painting these "flat black" before installing them. I used Rustoleums Flat Black 2 in 1 paint/primer. This makes the install much more aesthetically pleasing and factory like.
Riding behind the fairing is a real treat, the "cockpit noise" that I found so annoying is COMPLETELY gone. The wind protection is exceptional. The handlebars go all the way over each direction WITHOUT hitting the windscreen. It is very close but they do not hit. I normally sit somewhat slouched over and I still was looking well over the windshield, not through it. In case you're wondering my helmet is an old "Nitro Racing" full face helmet, nothing special. I can now comfortably ride with my shield up (sunglasses on of course) and enjoy it. I may remove the shield once the weather gets warmer, it's that nice. I noticed no distortion while looking through the windscreen. I did find the windscreen flexes a fair amount at times but nothing I am concerned with. After a while I didn't even notice it. I've read where some say the windscreen is "fugly" on the bike but I personally like the appearance, it DOES NOT take away from the looks of the bike. In closing, I highly recommend the Parabellum windscreen if you're in the market for one.
