I believe that you guys are being very harsh on Fenders. You see, while he has no "first hand" experience, he can only rely on what he reads, and he doesn't realise that while the 0-60 and 1/4 mile times that he sees for the CB450 are genuine OEM Honda times, they were achieved using entirely different methodology.
You see, while the CB750's times were conducted on a horizontal plane (drag strip) the 450's testing was conducted vertically. (dropped down a mineshaft)
Problem solved, evening all.........
