I have 4 bikes and I have to agree with your last statement, when I'm on the VFRs, I know the newer 600s & 1000s are quicker. When I'm on my 1100 Blackbird, then they think they might be quicker and end up obnoxiously revving next to me. When I'm on the busa, they make a scene till they recognize the bike then they normally sit quietly next to me at the light !
Of course one incident will stick out in my mind for a long time:
Sitting quietly at a light a few months back when a sebring convertible pulls up next to me, a few seconds later it starts revving so I turn my head and what do I see: 3 white haired old ladies in the Sebring with the top down, and the one in the back yells "Kick his ass Blanche...", I sat there grinning as the Sebring "sped off" about 5 seconds after the light went green
