I have seen some really cool Cafe, Bobber, Brat style 450's. I just bought one but haven't taken delivery yet. I believe it is a fairly stock 1972 CB. My initial thought was to strip it down a bit and maybe electronic ignition, upgrade the shocks, maybe custom exhaust, put some fresh rubber on it and ride it... past that I'm not sure. I'm guessing there are plenty of both owners, ones that want to keep them stock as possible and those that wouldn't hesitate to customize. The one thing I won't do is try to turn it into a hardtailed chopper. I'm new to the forum and haven't searched around much but there probably is a thread where members show off there bikes.
