I am seriously considering the 650 due to the fact that I "fit" better on it. I broke right leg and it is easier to throw my leg over the 650 due to the fact that is a bit lower. My only concern is that I want to go to South American on it and wonder about the cast wheels. I really don't think that I am going to "bash" it over big rocks/trees/and truck parts if I can help it.
I appreciate any "insights" you might offer about the cast wheels. I realize that if one hits anything big enough it will take out either type of wheel.
Again...thanks for you comments.
