Naw, just about the length of a loaf of bread. The stock 2 wheel GL1800 is longer, and wider than an Ultra Classic. When I rented a Wing last year before purchasing I got back on my 06 Ultra Classic and could have sworn I was sitting on a Sportster, it was that small feeling. Now since I've been switching back and forth between the 2 I don't notice any difference except the Wing is quieter and rides smoother.
Dimensions depend on the trike kit. A DFT kitted GL1800 is only 8" longer and 3" wider than a DFT kitted Ultra Classic, or half a loaf of bread longer:laugh:.
M3....you must be eatin French bread....the bread at Walmart ain't that big!
