FZR1000 6 Pot Calipers on FJ1200?

Hi all
Has anyone tried fitting the 6 pot Sumitomo calipers from the later FZR1000 on the FJ1200? I know the preferred upgrade are the gold/blue/silver dots, but I'm looking for something a bit more stock looking. The FZR has 320mm brake discs vs. the FJ's 300mm, I'm not sure if that may cause any issues? I do know the bolt spacing is the correct 100mm.

Thanks in advance!

What year FJ1200? Makes a big difference.

The early '86-87's will be a problem with the caliper lug spacing on the fork legs and the thickness of the oem double faced brake rotors.  You may still make it work with an aftermarket mounting plate and a single faced rotor replacement.

Here is the mounting plate I'm referring to:


It may be possible on the later '89-95 FJ's, mounted just as the monoblock calipers.

I have a '96, so they'll definitely bolt up. I also found out that blue dot calipers are fitted as a bolt on to FZR1000s, so I guess the only question is if the 6 pots are a worthwhile upgrade in the first place, or if I should just get blue dots in the first place... The reason I want the 6 pots (apart from the obvious 6>4 fallacy) is that we have mandatory inspections in my country and the blue dots are likely to raise an eyebrow so I'd need to swap the originals back for the inspection every 2 years.

Those 6 pot brakes are more hassle than they're worth. A lot of FZR owners swapped them for blue spots. The blue spots perform better, are lighter and don't suffer from corrosion effects as badly as the 6 pots.

If you're worried about them looking different, just paint them the same colour as your original calipers.

Got it! I just ordered all the parts for a complete upgrade - blue dot calipers, rebuild kit, 14mm brake master from an early FJR, XJR1300 clutch master and S/S lines all around. I'm pretty excited to experience the improved braking feel now!
