It will be interesting to hear how the SOHC 750 compares to the DOHC 750, even if the DOHC is the cruiser version.. I know that I am very happy with my CB550, and I previously owned 2 DOHC CB750's, and a DOHC CB900, all three "F" models. I've just been getting my 550 roadworthy, so I don't yet know how it compares to the others power wise, but it feels more agile, and that's a very good thing!
