I'm shopping around for my first bike, I'm looking for something vintage and expecting to put a bit of work into it. I found a 77 BMW R60 that runs but "needs work." I haven't seen it yet, so don't know what type of work exactly, but I was planning on doing chain, carb work, brakes, tires on whatever it was I bought anyway, but is the BMW going to be tough to find parts for, or real expensive. Or are bmw motorbikes different from their cars? just looking for some advice. thanks.
