Re: bones from southside chitown...
My wife is dead set against motorcycles, too. So first I got a moped, but I couldn't get it running. Flipped that for a Yamaha cub class scooter ... and that's not running either. But I'd managed to save up enough money to get a kit and a bike, so I went for it. She was not pleased, and shakes her head at me as if to say, "You are an idiot," but I don't care.
My advice, especially since you have a girlfriend and not (yet?) a wife: it's your money, spend it however you want, and without regrets.
