I have the stock '10 windshield with a MRA extension spoiler. I was undecided between the MRA VTA 6 and the MRA VTA 3. I ended
up going with the MRA VTA 6. It does what I wanted which is to give me a little extra protection in the up position in the rain.
I'm still not sure if I purchased the correct one but it works. The only reason I doubt my selection is the very noticeable difference
in the curve (horizontal left to right) difference. The spoiler has more curve than the windshield and I wonder if it would flow better
if the two were more in parallel. Perhaps I should have called Twisted Throttle for their advice, but I didn't thinking that they would
just try to sell me a windshield. I might not have been fair to them in my thinking. I'll edit this post later with a picture to illustrate
what I'm referring to with the curve difference.
(
some slightly off topic verbiage begins here) I'm only 5'6" and I'm mostly happy with what I have, but in the full up position there
is still too much back pressure pushing my head forward and down. Plenty of weather protection and no buffeting. I've been planning to cut a Calsi type opening in my stock shield to see if it will help, but I keep hoping someone else will do it to theirs first. I think it's supposed to relieve the back pressure and actually flow upwards but it just looks to me as though my chest or my tank bag would get pounded with water when riding with the shield up in the rain.
