I just put a cee baileys on my 1200ST. I don't really like the looks but during the cold months in Massachusetts it makes a huge difference. I've been commuting down in the high 20's to low 30's and the windshield keeps most of the wind off of me, which makes it much more comfortable. I found a great deal on e-bay, there was a place selling brand new cee baileys shields for around $50. They had a lot of different models for different bikes, and mine was shipped in the original cee baileys box with all the paper work. I don't know where the guy is getting them, but it was a great deal.

I am 6' with a 32" inseam, have a 2005 R1200RT and first switched to the CEE Bailey +1. I liked it. One of my support arms eventually broke and independant of that setback I was hankering to try the Cal Sci one to see if it was any better. I got the medium, and the big difference for me is less backdraft, so I am sticking with the Cal Sci.

If your shield came from CA and is from racers35 then you got it directly from Cee Bailey's. No mystery there. You got a new shield that is not A+ quality so they off the blems on ebay for a steal. Gotta love that and thank the Friday afternoon worker thinking about the weekend!

Ya that's where it came from. If it's a blem, you wouldn't know it. Great deal.

I had one snap after 18k miles. Dealer repaired under warranty. Although the CalSci screen is larger, I would argue against it exceeding tolerances for normal use. The stock screen is designed to be fully extended at speeds in excess of 120mph. Most of us rarely reach those speeds so the loading on the arms with a larger screen at "normal" speeds is probably not excessive. For the record, my arm broke when I went over a large bump which jolted the bike quite severely. BTW, it took the dealer the best part of 2 hours to repair. Required extensive dismantling of the front bodywork.
