I ask because I may need to buy replacement calipers for my old 9R and I want to fit something better and less likely to give hassle than the original 6 pots. Having looked around some race sites they all say fit the 750 calipers, but they aren't specific about which model. I've measured Elly's bike and 90mm centres seems to be right.
