Ok, so two posts, and the same question twice.

Are you asking what size hex-head to use in a bolt on your bike?  These bikes didn't have hex-head bolts on them originally.  Probably 6mm if it's a larger bolt, but it could be 7 or 8mm as well.  Smaller hex-head bolts for the engine cases tend to all be 5mm.

Beyond that - seriously, get out your wrenches and figure it out.

Tintin, the "Doc" is asking what size allen head bolt "Hex Key" to use on a a CB750K2 caliper, to seperate the two halves. The OEM bolts are of the "Allen head" (internal hex) variety. The answer is 8mm. Cheers, Terry. 8)
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"
