I've seen a few customers with Sportech windscreens on their bikes and I have yet to see one that lines up perfectly and has no gaps. The only windscreens that I've seen that fit with no gaps are the Puig windscreens, and these don't just come in double bubble, they also have stock style screens. We are able to get either the Sportech's or Puig's at Cycle Gear, but if you wanted to order directly from Sportech or get some more info about them, their website is http://www.sportechinc.com/.
