Put about 60 miles on my new ZG double bubble today. Buy one. I'm 5'8" and thought the OEM was OK. This is altogether different. It creates a nice area of still air behind the bubble with just a bit of buffet on the shoulders. Great improvement. My brother and I did a brief (only 10 miles or so) high speed run (130 sustained, brushes with 150 on occassion) on very quiet Tuesday morning on a very quiet stretch of interstate with the stocker in August (he was on his Ninja 1000). I WISH I had this screen then. A buck-fiddy would have been a little more comfortable. It's nice at 60 too. Go buy one. Oh, one of our members is a distributor (fasterspider a.k.a. Ray). Also, when you put it on they forget to give instructions on what to do with the bigger washers/spacers. They go on your rear view mirror attach points. The ZG is a thinner material (2mm vs. 3mm I think). You need them to snug things up. I hated the screen until I got them on. Now, it's awesome. The best mod. We'll see if I still say that after I remove the power limitation in 1st and 2nd. Ride safe all. Buy the ZG Dbl Bbl. Worth the money.
