My 650R is about to get a dinosaur for a stable mate. Pops is getting an old triple. It's either a 500 or 550cc. He went to look at it yesterday, and it sounds like it's in decent shape. Little rust, small tank dent, but it turns over and all the parts are on it. Probably needs tires, spark plugs, carb rebuild/synch- so guess what he's getting for christmas LOL Neither of these is his, but I like the old cafe racer look on these things. He'll probably keep the mini sissy bar and tall handlebars it has though. He's paying $100 for it- can't beat that, even if it needed completely rebuilt. Anyone know anything about them? I remember seeing a few sig lines of members that had them. What tires does it take? Tubes? Bias-Ply?
