My wife has decided that this may be the year she wants her own bike to learn and ride. She has been on the back of mine for years, so she has a general idea about the acceleration and leaning in curves and such. The clutch and brakes and all the other stuff will be new to her. My question is about which bike. I know there are 250's a plenty for her to learn on, but in my area, the used ones are going for the same price as used 650's. I think a 650 with a crash bar would be just fine, but she is concerned about the weight. She is about 5' 4" and about 130ish pounds, so I understand her concern. I have had both models of 650's before, so I know they are very balanced bikes. If we go with a 250, I am afraid she will "outgrow" it faster than she thinks (I know she will). If we go with the 650, I believe she will get used to it just as well as she would a 250. I just don't want her to be afraid of the weight so much that she doesn't want to ride it. I also know that a 650 will be of use for years before she will want to upgrade, not so with the 250. So the overall question is this, do I continue to try to convince her that the 650 is the way to go? Or should I give in to her fear of the weight and go 250? Thanks in advance for any input.
