Fitting FZ1000 Caliper to FZS600

[unfazed]

Correct me if I'm wrong, but doesn't the rear R1 bluespot have the same piston diameters as the fzs600 standard caliper.

I know the pads mount differently, from the bottom leaving the caliper more open to remove water/road crap, but if the pistons are the same it won't affect brake feel at all.

You are correct the pistons in the R1 rear Bluespot are also 38mm diameter
