I have read a lot of "reviews" on this site, so I figured I'd chime in with my own. This meant to be my personal opinion, and nothing more. I am not a professional... well... anything. Just a guy on the internet speaking his mind.
I have a 2009 Ninja 650R (Green). The bike has (not that it matters for windscreens, but people always ask...) a Corbin seat, Arrow Exhaust, sliders, Pazzo levers (long) and heated grips (I ordered the heaters from Aerostitch and made my own harness).
I live in the Bay Area of California, and spend most of my time on the bike commuting up and down 280 and 101. On 280, a significant amount of my mileage is spent in 6th gear at about 80mph. On 101, it is more like 4th or 5th, at 55-60 (down to 40 if I have to split). I ride at all times of the day.
I am 6'2" tall, with a 34" inseam
, and prefer to ride relatively upright. I do not hunch over the tank, and don't particulalry "tuck". I like a vertical riding position because I can see upcoming traffic better.
I put 3,000 miles on the stock windscreen, and felt that I should try a different screen, to block more of the wind on my helmet.
I ALWAYS wear earplugs, and wear a Scorpion EXO-1000 helmet.
WHAT I PURCHASED:
I went here: Ninja650Shop.com Ninja 650R Parts & Accessories 402-934-6627
And purchased the Zero Gravity Sport Touring windscreen in Light Smoke.
The cost was 89.95 plus shipping. I have used the ninja650shop in the past, and their service is good. In this case, it took more than a month to get my screen, as they were backordered. This wasn't ideal, but ninja650shop explained this to me, and offered a different screen if I didn't want to wait. So all in all, an excellent shopping experience.
OK, SO HOW WAS IT?
Firstly, the installation is obviously a breeze. 4 screws and you are set. The Screen fits well (no fooling around, it just fits correctly) and the "smoke-ness" (darkness) was a nice match to the bike.
It does stick up more vertically (2" more than stock, according to my measurements) but it looks good. Doesn't look dorky at all.
However (and here is the bad review part), there are two things I don't like:
1.) It is a little thin. I don't really care about thickness visually, but because the sport touring is somewhat tall, and doesn't have any structural ridges, or a "lip" along the top like the stock one, it wobbles at speed. This is distracting to me at speed, seeing it "twist" back and forth at the top as I ride. I felt that if they had put an "upturned" lip at the top like the stock screen, this would have been avoided.
2.) It was WORSE for me than the stock one as far as wind noise. Wait... what? Yeah... you read that correctly. I swapped screens back and forth a bunch of times and rode at different speeds, and what was happening with the stock screen is that the wind was hitting me under my chin. So while I felt a steady blast on my chest, my helmet was in cleaner air. When I swapped to the Sport Touring, it is, of course, taller, and moved up the flow by about 4 inches... this hit me square in the face, and the result was disappointing.
I very much wanted to like this screen, and I think if I was shorter, it would have been perfect... But alas, I am not, so I removed it and put the stock one back on.
I have never tried a Double Bubble, and some folks swear by those, so maybe I'll give that a go.
I also realize this isn't an 1200GS BMW. This is a sport bike and there will be wind. I get that.
