Sweet thread. I love my BW80 to death. Funnest bike I own, really, because you can't crash it and you can't hurt yourself on it. You're so low to the ground that when you fall/tip you can just push yourself up with one hand.
My friends nicked named her "marshmallow" because, well, it's like riding a marshmallow.
It's thrashed but keeps on going. I got rid of the oil tank and mix my own fuel. It needs a gas cap and a throttle cable.
