Selecting a windhsield is tough. You actally have to sit on it to see how it fits. And it also depends on how tall you are. I have a OEM Suzuki windshiled so I dont know anyting about the one your talking about. I can measure mine tonight and tell you how tall it is but I dont know how much that will help. Because once you get it installed it will have to be adjusted to your hight.
When you adjust it, you want to be able to see over the top of it. So if it rains or gets covered in bugs you can still see where your going. Right now mine is adjusted that if I look out to the horizon when I ride. The top of the windshiled is about paralell between my nose and my upper lip. That way I can also duck down If I want to. (just my personal preferance)
If you set it too low the wind blast will hit you in the top of your helmet and whip your head arround. Even after you get it set to where you think it needs to be. If you go out and ride it you may find it needs to be adjusted again.
Hope that helps.
And if you have been riding without a windshield. ANY windshiled will cut down the wind A LOT!!! I rode 300 miles before I installed mine. it was brutal. It takes a real man to ride down the highway without one. And to me a windshield is worth every penny.
