I bought my wife a KLX140l, she likes it for the electric start and the good power, granted it isn't a speed demon but a great little bike with good torque. I put KX100 forks ans shock on hers, not that it necessarily needed it. prior to that I had built a KDX/KX hybrid for her and I think if she spent time on it she would like it but for the few times she rides the KLX is probably fine. I think the KX100 isn't noticeably strionger than a 80 both are pipey, if your going to ride around your property the KLX might be a better choice, have you removed the air box lid and installed a pipe, they run pretty good if you do, of course you will have to jet up.
