Direct swap is the CB/CM 400/450 models, not the CB450SC which has a different front mount setup
I suspect it won't, as the 400 series frame has a wider backbone than earlier models.I was hoping to get some clarification as I have been reading on this after picking up a 1980 CB400n. Will a 74 CB450 tank fit on the 1980 Cb400n? Hoping to find a tank more suitable for the scrambler look.
Thanks in advance!
