Would you say that if it were two chicks riding two-up?
Funny that society has the impression that two guys riding together on a motorcycle have to be gay...
I saw guys riding two-up all over Europe. Granted, I did a double take when I first saw it. However, I didn't see anyone else pointing, laughing, making jokes, and going through other general histrionics over it. I think their society is a little less homophobic than America, where most straight guys being called homosexual is a fate worse than death.
