Scab
I got nothin' here...
Well, just got home. VStream waiting in my chair. 10 minutes later, on the road.
First, some background.
Old screen - stock
Me - 5'11", sit CLOSE to tank
Bike - set-back risers, stock seat
When riding with the stock screen down, the air hits me in the chin and shoulder area. There is a lot of wind noise, but the air is clean and just sounds like high-speed blowing. The air stream removes most any pressure off the hands and wrists. At about 90-100, the helmet starts generating lift and actually tries to raise off my head, adding pressure to the chin strap. The ride is comfortable in this configuration but is noisy. And of course, temperature sensitive. As soon as I start to raise, beginning with only an inch, air turns dirty, lots of turbulence. This turbulence builds as the screen rises and back pressure also builds pushing me towards the screen, putting more pressure on hands and wrists. Completely raised, wind is blocked from body, huge amounts of noise, popping, buffeting. Somewhere around half up to completely raised, head starts to get pitched side to side. When full up, side to side motion is more steady and rhythmic.
Now for the VStream.
I started out with the screen in the full down position. I first noticed that I was looking for 6th gear. Then I checked my speed. I have become accustomed to relating speed to sound. No more. At full down, highway speed, slight noise. I mean very slight. A little puff, puff. But it should be noted it is a windy day today. I start to raise the screen, just an inch at first. Silence. Or, so I thought. I raise some more. STONE DEAD SILENCE. I'm thinking, "Gee, is my bike supposed to sound like this? This thing sounds gooood."
Pick up ahead. I fall in behind the truck which is running normal highway speed. Usually, this would mean my air turns very dirty and turbulent. But no, just the slight puff, puff comes back. Bike is very stable in the air stream.
Turn around, time to twist it. Screen is still full up at this point. So I twist. One interesting point here, as I lean to the right in a sweeping curve running about a 100. The bike seemed to have a little resistance to lean. Nothing drastic, nothing dangerous, it just didn't fall sideways as easy as it did before this screen. This could be nothing, this was my only high-speed curve on this test so I can't say if there were other forces contributing or not. I will pay attention to this as the testing continues.
At high speed, still NO noise. Bike is extremely stable. I feel LESS side to side variance from wind than I did before this screen. Hell, I can HEAR the front tire contact with the road! The silence is extremely deceptive regarding perceived speed!
There is NO back pressure that I can detect. External body forces are similar to sitting on the bike in your garage.
I could feel air around my ribcage, but it did not make noise. I placed my hand to my helmet, palm forward, thumb against helmet, fingers spread wide. NO wind. I started to move my hand outward and found the air stream about 8 inches away from my helmet. Identical on both sides.
I can't comment on temp yet. I didn't ride far and we are having a cool spell this week.
HOWEVER! If you do not wish to look through the screen, this is not the screen for you. At full down, I am looking over the screen by about 2 inches. At full up, I am looking through the screen 3 or 4 inches down from the lip.
Quality - Top Notch, and this thing is THICK!
Fit - Perfect!
That is pretty much it for now. I will see 100 miles tomorrow (work commute) and then I am leaving Thursday morning for a 1300 - 1500 mile camping trip to MO. That should be a good test for the screen and my neck.
