We both passed the MSF Basic Rider Course last week and the wifey enjoyed it more than she thought she would. We picked up a Marauder GZ250 for her today. It is a 2002 with 4K miles and we paid $1800 for it. She rode a Rebel for the MSF course and I rode a GZ250. It is like a mini bike to me, but it is light enough that she feels fairly comfortable on it. I test rode it and was actually able to get it up to 60. I had to really wind it up, though. Anyway, it was cheap enough that if she decides to quit or wants to move up, we can get our money back out of it. It even has a few cool upgrades: cast wheels, back rest and luggage rack, Dual exhaust, adjustable risers and drag bars, and a cheesy looking homemade aluminum highway bar that will be coming off. here is a link to the add w/ pics:
