Zero Gravity Double Bubble - Follow Up Review
After going to Willow Springs with a Zero Gravity Double Bubble windscreen installed, I have to say I'm very satisfied. Aside from its lack of DOT approval its performance was stellar at "the fastest track in the west." I hit 145 MPH on the front straightaway and had noticeably less wind buffeting than the last time I was at Willow Springs with the stock windscreen. It creates a slightly bigger pocket of air without changing the aerodynamics or handling of the bike at speed. I guess these things are used by racers for a reason.
