..^^^^ do yourself a BIG favor!! Find a good used Rebel!! They are cheap, easy to fix, WELL BALANCED, and not to "torquey". I will swear by them for first bikes every day!!
Not a big investment, IF she likes it, have her take her test on it.. ride it for a while and we all know it will only be a matter of time before she "wants something faster"...,
I made the mistake of signing my wife up for the H.D. (Beginners-yeah right) class. I did not go with her due to work. She said she got A LOT of REALY good info safety wise, but the class (atmosphere) was intimidating. She made it as far as the first riding day. The bikes were fine but she had NEVER handled a motorcycle before... and they actually expect a first time rider to pass the test the following day.
... anyway, I bought her a rebel, on the weekends we would go to a (unoccupied) parking lot .. I set up cones and plastic trash cans. After a while she would practice tight slow turns on her own.
One morning I woke up (working the late shift).. she says "look what I got".. she shows me her endorsmsnt.. she went when she felt comfortable..
And YES, after a few months.. she wanted something "faster".. so, now she rides her 72 CB450 Dohc to school everyday (weather permitting).. and YES, I sold the Rebel for what I paid for it..
Sorry, I just realized you said she has "NO" interest.. I first read "has now interest"... well maybe this will help someone else with a spouse that maybe a "little skittish" riding for the first time.
