I know everyone has one, so what's the opinion on the Honda CB550Four? I know the CB750's had a pretty massive following, but there's a very nice 550 near me that's at a very nice price. My only real concern I suppose is the age. Being a 76, there probably aren't many parts available for it. If it was the 750, I wouldn't be so worried since there's a pretty large aftermarket for them, but the 550 support seems thin on the ground.
