These are my bike brakes, no i can tell you, i have brakes.

what calipers are they , I've seen  ones like those on eBay  off a Suzuki ?? wondered if they would be as good as blue dots or better

They look like 6 pot Sumitomo calipers from the YZF750/1000. I've got a pair on my newer FJ. My old FJ has blue spots and the 6 pots are better - lots of power & feel. Buy a pair if you find them. They are a straight bolt on for FJs with 4 pot calipers.

There are some problems with using the 6 pot Sumitomo calipers from the YZF750/FZR1000.
They weigh a ton, much heavier then the blue or gold spots. They do not fit, the friction material on the pads overlaps the edge of the rotor. Every thing will be good until the overlapped area of the pads touch, then not so good! They also ware the brake pads to a taper (thin at the outer edge). You will also need the master from the downer bike. 12 pots need the larger bore master. I had a set on my FJ before I got my first set of blue spots.  They are very nice looking calipers, but they are not better brakes then a sorted pair of blue (or gold) spots. Yamaha abandoned them for the blue spots on the YZF's starting in 97, even the R1's ( a much faster motorcycle then the  YZF750/FZR1000 ) used the blue spots.

The last time I saw a MotoGP bike it used 4-piston calipers (granted, carbon fiber, but still), and the same for a World Superbike. I tend to think of 6-piston calipers as a product of 90s penis envy.

YZF750 I believe.

125 British pounds, must charge by the piston  ,, they look good though

Once again you are an invaluable source of information. Thank's for the info looks cool but not the best. Just to let you know I bought a set of gold spots off of a 02 R1 working on lines and master cylinder. Thank you !!! again.

Kurt,

You will like those brakes! Stock pads? Thats what I use.

[FJ Flyer]

And use the stock R1 drilled caliper bolts.

Caliper bolts? why change the caliper bolts?

Thank's Kurt

A light weight monoblock caliper deserves light weight bolts....less unsprung weight.... very easy to drill and safety wire for track days....

[yamaha fj rider]

Ko makes perfect sense to me. You are just faster, more high tech than I am but I will catch up. Ordered the stainless hardware kit off ebay this week should be here tomorrow. They were asking $45.00 I placed a bid for $40.00 and it was accepted plus the $8.00 shipping.

Six pot calibers like this

Also, they are designed for operating with the heat of breaking.  Suppose the FJ bolts would be okay, stay away from stainess.  IIR the words of Hippie Cain, they are too brittle.
