That's a pretty cool bike, with the triple discs and all. Probably be one the best commuter bikes ever.
I used to own an 82 CB450SC (nighthawk) that had a boat load (45k plus!) of miles on it, used a commuter. It was pretty nimble, and could hold it's own in town pretty well.
It's too bad the single cam 450 is one of the most boring engines ever.
