I don't know enough about this to make any kind of informed opinion, so I won't offer one. However, it clearly made you uncomfortable, so don't go. I'm not sure why you're second guessing yourself
Exactly what I was thinking. I'd started riding on the street at age 13 on a S90. By age 14 I was on a 305 (scrambler, wish I still had it) , then at 15 on a 750. Of course, that was more than a few years ago, and things have changed.
