I agree with alanh. We might as well be talking about a book none of us has read.
I guy in town, who I don't know well, has 50K miles on a Honda Helix 250 (I'm not sure about the Helix part). He obviously rides it all the time. I'm sure it's got a belt in its drive train somewhere.
So I approached him the other day in the coffee shop, interrupting him as he read the Arizona Daily Star, and said, "Hi, I'm Ted White. I just looked at your scooter and I'm amazed at the mileage. Have you ever had any trouble with it?"
He surveyed me, stone-faced, for a moment. "It's a Honda," he said, and returned to his newspaper.
I suspect I won't get to know him well.
