Cute little bikes but just doesn't do much for me. I can see new female riders being attracted to these.
Now the 400's as mentioned...humm...yep I could see me interested in that.
As far as the comment about anything more than 500 hp in a rear wheel drive car(?)...sure...as long as that is at the wheels.

That's where I'm at with my car and I'm fine with it. I'm not in to revving it up and dumping the clutch from the light anyways.
