All the blue spot calipers are the same as far as R1/R6 blue dot. I think even early FZ1, are the same. Gold spot calipers are also same except they have alum brake Pistons instead of the steel ones in the blue dot.
Good choice. When I stalled my R1 calipers I had to upgrade the M/C also. With the stock master the brakes felt a little wooden. I went with a master cylinder off an FZ1 2005. Inexpensive and kept the mirror mount in stock position . Solved the wooden feeling.
