Flipup-Helmet... I can't remember seeing him flipping the visor down at any point on the trip. That Goldwing windscreen is like a 7 square-feet or something
Thats exactly where I mounted mine, I pulled my throttle cable out from the little bracket that keeps them in place and used the bracket as a base for one of these bottle cages.
Under the hole I used a metal bracket with the throttle cable router in between.
Voila, no cutting or fabbing.
A large cup blocks my rpm gauge but I never look at it anyway, and I'm not on a road trip with a cup of coffee anyway.
