Have to chime in here, agree for the most part with keeping it small and easy to operate. That being said is she will play a huge part is enjoying what she is riding. My Wife being a new rider (indicated it was the only way to spend time with me) absolutely did not want a low slung Harley. She wanted a duel sport adv bike. "well honey, being 5'2" it limits your options" "Dont tell me what I want and can ride" ok ok ok. As I was in the market as well, we set some ground rules. Im a big proponent in riding similar bikes since road issues/ repairs can be very similar; often times with interchangable parts. Given the height differential co-efficient and that most bikes even with after market bones cant get low enough for my riding partner we went with a factory lowered BMW 700gs, then shaved the seat. I bought the 800 adv model. She can sit the bike flat footed. Growing up riding big dirt bikes, I did not understand how comforting it is to touch flat footed. I would make a plug now for both of you to ride DR650s if possible. Those thumpers can be raised/lowered to fit any rider and again operate the same. Actually looking at purchasing another and lowering for her for the trail trips. Insist on a riders course, let her ride for 6 months and take the advanced course. As all have indicated, only saddle time will make her truly worthy. She will make mistakes, she will scare the living crap out of you. Wifey been riding for 3 years now and finally Im not on edge everytime she jumps on. Armour the bike, ATTGAT her up. I have picked up that damn 700 hundreds of times from low/no speed naps. Whatever bike, get her some unloaded miles on it before loading. Hopefully she will enjoy it enough to keep riding. The bottom line is however you do it, MAKE it happen; the older they get the less and less amount of time they will have to spend with you...... If you want a yellowstone/glacier adventure; hit us up.
