That's correct -- but false ID's are accepted without question, so don't worry.
Okay, there's no limit that I've ever heard of, really, and I think you could ask more than one M/C rider for living proof of it. I won't mention any names, but there's one rider that's currently active in the sport, who's over 60, and is also consistently over 200 mph. No names -- but his initials are Scott Guthrie. Hell, I'm 58 and don't have any plans to cut back. . .
