This weekend, I'm building an overhead for my motorcycles (4 posts and a roof). I'll be adding a 2012 Goldwing to my collection of vehicles as soon as I get some more business. I'd like to drive the Goldwing underneath without bending the antenna, and was thinking about 6' clearance from floor to ceiling (since I'm only 5'7" tall). Should I take the antenna height into consideration so that I can sit on the bike and ride it underneath without any issues? If so, what is the minimum height clearance from floor to ceiling?
