I have run on the Dark side over 80,000 miles on Gl1800. Two Wings and now my new F6B. I am very happy. I run Bridgestone Ecopia, or how ever you spell it.. lol....Run 31 psi single rider and pull Bunkhouse camper. A big ole tire is nice for quick stops. Now have trailer hitch on F6B. Isolation box was not plug and play as there is no trunk on the F6B. Go figure? I spliced it into the wiring.
