The windshield is huge! I can ride with my visor open without any wind hitting my eyes. I do hear a bit of buffeting, but it is a big improvement and will make riding much more enjoyable for me. For the record, Brammo uses the MRA Racing Screen for their Empulse LE.
Well I mounted the same screen (only in smoke grey) today and didn't really find it huge. Kind of sporty-petite in width, moderate in height. I guess it's what you're used to. Also I'm 6'1" with a long torso, and am sitting a couple of inches higher on a Bill Mayer saddle, so the wind hit me right in the helmet, which I like. A level placed on the top edge of the shield hits me in the center of my sternum; placed on the top of the spoiler, it hits just below the top of my shoulder.
At first, there was a low to moderate amount of rapid buffeting. I had placed the spoiler support arms in their highest position, parallel to the windscreen, with about an inch of gap at the bottom between it and the windscreen.
Part way through my test ride, I stopped and adjusted it so that the support arms were pointed more forward (as in the OP's photo), but tilted the spoiler back so that there was about a 2" gap at the bottom. This ended up working very well: Very smooth air up until about 70 mph, and then only very slight disturbance of the flow up until 85 mph, where I stopped accelerating. This worked better than any spoiler I've tried in the past (about 3, IIRC).
The screen appeared very solid at high speed even though there's no fasteners holding the bottom edge. I put some rubber from an old bicycle inner tube at a couple of points on the bottom to protect the CF headlight shell and to dampen any vibrations.
I feel this screen won't give me real protection in the rain as much as larger screens I've had in the past (Parabelleum Scout, e.g.), but I could tell that the ride on the freeway was much enhanced by having no wind pressure on my chest. I liked the looks of it and will post pics soon.
I'm eager to see if I can measure any improvement in range. I did my Standard Acceleration Test which is a WOT run up a steep hill about 0.3 miles in length to the crest. Prior to the screen I could get to about 70 mph and today I hit close to 80 mph, placing the Empulse above my 43 hp Yamaha 500 cc TMax scooter (75 mph) and below my 109 hp BMW R1200R (90 mph).
BTW, the written instructions were cr*p, and I ended up relying on the pictures only. One of the written instructions made me laugh out loud:
"5) Position the windshield in the desired position and tighten the screws lightly on the clamps (which screws? Which clamps? This is unclear."
Obviously, the translator's notes got copied and pasted, unedited, into the final text!
Bottom line: once I dialed in the spoiler, I like this screen: both its looks and performance. And for very hot days, loosening two bolts is all that's needed to slide out the support braces and lift the screen off the bike entirely.
