I am running with no shield right now and i really like it. Clean air. I don't go much faster than about 70mph and I don't get to take long trips much.
However, I would like to make the bike look a bit sportier and a sport screen is one of the things I am thinking about.
How does this change the wind. Does it give folks more turbulence at up to about 70?
What a coincidence that you would start this thread now...after mulling it over since I got my R one year ago, two weeks ago I went ahead and installed the sport windscreen.
Here are the particulars of my situation: I am 6'3" tall, with most of my height in my torso. (My trousers need only a 30" inseam, but I must wear 'long' sizes in shirts, jackets, etc.) I am 61, and have been riding more or less continuously since I was in my late teens. My 2013 R1200R 90th Anniversary Model is my third BMW since 1992.
My last Beemer was a 1995 K75s, which I bought brand new. It had that small fairing and short windshield, which directed a blast of air at the base of my helmet. I tried various remedies over the years, none of which was successful, so I gave up and learned to accept the noise and turbulence.
When I bought my R last year, I loved its 'naked' styling, but I also really liked the look of the sport windshield. I didn't have any illusions about that little screen offering any real protection; I saw it only as a styling addition, and my only real concern was that it would add unacceptable noise or turbulence.
I ordered the sport windscreen from Gregg at Max BMW in New York, and installed it two weeks ago. I really do like the styling, and I think it adds to the R's already-good looks. I have ridden almost 1000 miles with it, on both Interstate highways and local and secondary roads, at speeds up to about 95 miles per hour. (No, I don't normally ride that fast, but I have gotten up to that speed on occasion while passing someone or merging onto a highway.) Here is what I've noticed:
There is definitely an increase in noise -- but NOT turbulence -- over the stock configuration. The wind strikes me about mid-chest, and the ride is definitely a bit louder at highway speeds. However: I wear custom-molded earplugs, with speakers installed so I can listen to my XM Radio, so the noise, while noticeable, does not really bother me. At its worst, it is about equivalent to what I had to tolerate from the K75. (I have ridden with this sport windshield at highway speeds without the earplugs, by the way, and find the noise level tolerable.)
Last week, I got caught in a light rain, without my rainsuit, and I was very pleased to note that on I-95, the sport windscreen kept my torso and hands dry. Apparently, the little 'ears' that project out from the windscreen are not just cosmetic: They direct airflow around the rider's hands...very good design!
Bottom line: I'm glad I bought the sport windscreen. I love the way it looks, and it is indeed at least minimally functional, with an uncomfortable noise level.
