So it's a slow night & I am reading the latest issue of Motorcycle Classics (one of my faves). I came across two references to a 1974 CB500. Now I know outside of NA the 500 continued on past '73 for a number of years, but I figure MC is pretty strictly a US mag. I checked the info on our site (I did mention it was a slow night..) & interestingly there are precise dates for the introduction of the '71~'73 model 500s but not for the 550s. Is it possible there are 1974 500s built in the first three months of that year in NA & then the 550s came out? Enquiring minds want to know...
