No, in the same areas I'm out riding in I'll see tons of sport bikes, touring bikes, sport tourers, etc, but it's nearly always the cruisers that will be parked in front of the bars and restaurants. Actually, I'll agree that most riders, not just of sport bikes, treat them like toys. Look at bikes for sale on Autotrader or someplace like that and see how many miles most of them have on them - not too many. And that goes for Harleys as well as sport bikes. In fact, while many sport bikes are owned by weekend posers, so are many Harleys. You know the guys: buy their new Harley and a bunch of standard issue black leather, beanie helmets and such at the same time; trailer their bikes to the rallies and then ride them in the last 20 miles.
BTW, you know, there are more types of bikes in the world than cruisers and crotch rockets.
That's why I have a sticker on my sissy bar that says, "SILLY YUPPIE TRAILERS ARE FOR BOATS"
