Aren't SP2 disks lighter/thinner than SP1? Would they have to be swapped or would they work with SP2 pads? ???
Are the axles sizes the same? Would bearings have to be swapped therefore?
I somehow remember that between some CBRs and RCs there are differences solved by bearing sizes and somehow SP1s and SP2s had some difference. I also think the 929/954 disks were larger than on RCs, right?
Front axles are same size, SP-2 unit is allegedly 0.5lb heavier than SP-1 but I've never weighed them. They both fit fine.The SP2's brake disks are thicker than the sp1. I believe that these are interchangeable.
