I've never found chicks in bikinis on bikes or cars hot, quite the opposite actually. I would love to get a Harley though, or any bike of similar style. I hate crotch rockets.
I find hot girls hot no matter what they do.... well.... to a point, I'm sure someone could find something on the interwebs. But anyway....
The only style of bike that I can see riding is a crotch rocket of some sort. Sure, it could be a sport tourer, or something of that sort but the cruiser style bike is woefully inadequate on a lot of areas, mostly handling and braking. The increased performance in all aspects make the sportbike safer, in my opinion.
If I was going to ride a cruiser style I'd probably end up with the Yamaha VMAX
