My '89 660 set up as a fixed gear. (Don't worry, I haven't dremeled anything off....

)
It was gray when I first got it, and had it powdercoated. It started developing rust under the powdercoat so I stripped it off. I really like the naked steel -- I may just buff it up and spray it with rustoleum rust inhibitor and ride it like that until rainy season returns. I'll post some pics later.
