Right, just buzzed round a few forums and found a member that has just bought a aftermarket master for a GL1000K1 from DSS. He says that the master piston is 14mm. Had a quick look on DSS at the aftermarket master for a CB550 and the write up states that the replacement sohc master is also 14mm. Defiantly need to do some maths on this one.John, you are right on the dia X volume but, i am thinking what would one need for a twin caliper set up? In the way of master piston dia.

They look identical but they have different part numbers plus the 550 does state it's a 14mm bore suitable for single discs whereas the GL version doesn't state the bore but does say it suitable for twin discs.
