Riding it home from work yesterday I was coming up a straight stretch and a fellow was checking his mailbox ahead. He was staring at it sort of puzzled like and watched it all the way past him. I don't think he quite grasped a scooter going by him at 60 mph and making a BRRRR noise. I've got a Malossi muffler that came with it that's supposed to be a bit louder, got to check it out.
