My 21 year old grand daughter wants to ride with us. What is the best beginner Classic Street Bike to buy. We ride GL1100s, would like to stay in the 1980-1985 range. Thought about Silverwing or CX500 custom, but scared it would be to heavy to start with. She is 5'9" and plays college basketball, so she is strong. all suggestions welcome, and I like to work on stuff.
