has any one ever heard of a quick detach shield blowing off or loose while parked in a heavy wind or while being haulded in an open trailer?

 

Dude, I live where it rains in buckets most of the winter, added semi wash and debris, I get hit by all kinds of stuff. Ive had the same shield on two bikes, and it has never moved yet.

 

Never heard of that, no.

 

If it wasn't attached or installed properly, it could happen. Properly attached, they will stay put.

 

This past spring I was in the Joshua Tree area, the santa anna winds are really bad.... I had the windshield blow of while sitting at a light. If i wasn't headed into the wind, It wouldn't have made it back with me.

If I lived in that area, I would consider a bike with the batwing.

 

It happens rarely, but only when the windshield is NOT installed correctly. When put on correctly, she'll stay put.

 

I had a quick detach shield on my last bike. It was the type that all you had to do was pull on it to take it off. I rode over 26K miles with several cross country trips in all sorts of weather and never had a problem.

 

Last year I was motoring down I-5 to San Diego from Oregon, first stop was Redding. The next morning the forecast was 40 mph winds, lucky for me it was a tail wind, I got 50+ mpg going 85 MPH.
When I stopped for lunch at some dive, I dropped the kick stand, got off and watched my wind shield almost get blown off my bike. I moved the bike next to some bushes for better shelter and had no issues after that.
That tail wind was the bomb - very little turbulence and I spent almost 3 hours in the saddle before stopping for gas. Needless to say, I was happy I wasn't riding north.

 

Yes, happened to my brother on his RK this past Nov. We were down visiting them, rode to Kitty Hawk in the Outer Banks to visit the Wright Bros Museum, and in the parking lot, a gust caught his windshield and blew it across the lot. Everything was ok, a few light scratches, but we sure found out (the hard way) why they chose that area to make the first airplane flight!!
