Make them as beefy as possible around the mounting bolts and have a smooth radius from the shank into the ends, yours look a little too square at each end which could cause a stress induced failure. Best of all would be completely parallel bars raduissed off at each end with the eye bolt holes machined in, if there's room for wider dogbones in the set-up, which it looks like there is on your bike. Some, like my old Bandit's, needed to have slimmer shanks to clear the swingarm, but yours don't.
