Here's one the Brazilians made later and it's only £350

Ok, ignore the tassles and see this CB450 '94. It was for sale in Brazil found on the net for 1,200 Brazilian Real... that's cheap. It's about £350. Ok the ad was October 2007, but you get the idea.
It's pretty obvious they don't use salt on the roads. It's clean and tidy and the best part is, the Brazilians seem to look after them too. The seat has been cut down, it's a tall 32 ins as standard, the horn has been moved to make way for the tool roll... all in all a nice job
