This thread just goes to show how uik and effective this forum is at getting to the bottom of tings ... brilliant ;D .. so the 50mm arm/ caliper comes from later 750's + 550F1 ?
Trigger:
Ewan, now that is another question. Anyone out there have a CB750 F1 or F2 that could clear this up. Ewan and I may have some parts for you ;)

Very interested to know the answer to this too. The second disc setup I recently sold also has the same problem.
I removed it from a mates non running '77 550, so it either had a front end swap at some point or it was a model change.
I believe the disc is the correct 550 size, but caliper and bracket do not match with the new owners forks.

yep, that looks like the same 50mm bolt hole centres caliper arm ... which then seems odd that it came off a 500, unless the disc was also a larger 295mm non standard disc
Did the disc also come off the 500 ?
Does the purchaser mean that the caliper arm bracket holes dont line up with the holes on the fork case ?
What bike is he trying to fit it to ?
.. and he might not want to use the stainless bolts ... was told their low tensile strenth makes them a bit dodgy as disc bolts 8)
