As sold, except for the tail light the 1100 is a throwback to the DOHC CB750F/900F/1100F models.
Lot's of reviewers tried to tie it to the original SOHC4 CB750's, but all of us here know that is incorrect.
I do like the kit used on the OP's bike, but the cost is just too much. You can get a nice K6 for what the pipes alone on that bike cost.
