It's an 06 Ninja 650R. After reading a lot of reviews etc. (many of them claiming it was a good starter bike, oddly enough), I let her talk me in to it.
I cannot believe how much fun this thing is! And I haven't even had it out of the parking lot yet (been practicing turns, stops, etc. all day). I'm going to keep doing parking lot stuff to get as comfortable as possible with the bike, and then take the MSF course later in the month (the soonest they had available). I had no idea what a HUGE difference riding a bike would be, but I think I'm giong to really enjoy it.
We also picked up leather jackets, gloves, and helmets for the both of us. She's going to take the MSF course too so she can ride 2 up with me, and so she can ride it by herself eventually.
