My daughter has a motorcycle endorsement and some riding experience. She is also 5'8" and is a very athletic person. However, she didn't care for my T100. I was sorta surprised, so I asked her what she WAS looking for in a bike. As it turned out, she wanted something much lighter...she always felt she was not in "command" of the Bonnie. I suspect this is true for many women. The average weight of American females is only 80% of their male counterparts. Therefore, in order for them to have the same experience with a Bonneville, the wet weight would have to be 400 lbs (vs 500 lbs for guys). Factor in height differences and you can see that there are damn few choices available to the ladies. No wonder that the Honda CBR250R (357 lbs wet) and BMW G650GS (428 lbs wet) are popular among women...they are actually sized to work for them. I suggest that if you really want your girl to enjoy motorcycles, you need to stop thinking about what you want and help her to find what she wants.
