so whats the deal with these gold spots then ? do they fit? are they the same as blue spots ? not the later ones that are clearly radial of course the ones i see from time to time that look like blue spots

I fitted a pair to my trx without any problem. AFAIK, they are almost identical, but might use different materials to make some components of the caliper. Perhaps someone could clarify. That's about all the info I could find. Oh, I think only the R1s got them, not the R6s, and maybe the XJRs. This is from '02/'03 I believe, just prior to radials, so they will be younger than blue spots (unless off an R6). And they look cool!

Not certain, but I've heard the pistons are made from a different material, thus enabling an improved heat transfer.

so as good if not better than bluespots then and certainly worthy of buying for a good price to pop on the trex

fit them but get yourself an r1 r6 thundercat race master cylinder or you will be afraid to aply to much presure my mate on his xjr actualy outbraked me in the summer when a sheep run out in front of us my rear locked up and I was afraid to aply more front brake

Sorry for stating the obvious....should read reducing heat transfer.This will reduce the chance of the fluid boiling.
Having seen blue spots and gold spots, there appears to be no difference exept the colour.
I would say both are good and go for which ever is cheapest.

Well, in this case, that is an improved heat transfer, isn't it?

Thanks for correcting, that's what I meant. If it's true, that is, or if they're just more bling looking...

I was actually scoffing at the idea of a different material being used (not your interpretation of heat transfer... And just a gentle tug on yer chain intended by the way )

The only change I can see is the colour of anodising.... Yamaha are well known with perservering with the same old caliper design as long as possible: Check out the TRX rear from the early eighties for proof!

They are identical (as are the silver spots found on the 2006/7 fazer)

whatever the color they need to be kept clean they do suffer from corrosion if not looked after ( on the pistons )
