I started on a 650 BSA Rocket in 1963 at the age of 20(then a BIG bike) & it is amazing that I can tell that story. Might be better put to say no regrets but many !wow! moments happened to me. There was no MSF then & I probably wouldn't have gone if there was as I was not only young but athletic and thought I owned the world once I got the clutch release thing figured out.If you don't think it was right for you, you're right, though extending that thinking to others and their capabilities is the source of my disagreement. I did start on a big bike at 18 or 19, no regrets then or now.
Your daughter has the gift of guidance which needs to be tempered by reason. A big part of that is just how much she wants to ride. FWIW, my kids never had any desire to ride a MC(wife included) & still don't other than one son who has a lingering interest that's never resulted in any action.
