Yamaha TRX850 Enthusiasts Forum

Hi everyone,

I'm thinking of changing my stock front brake calipers for blue spots. Thing is just about every late Yam has a set of blue spots. So the question is, what model and what model years of Yamaha will bolt straight on to standard TRX fork legs ? Late model TDM might be the obvious choice? Thanks.

NON RADIAL blue, silver and gold spots will ALL fit the TRX

Silver to match the frame is nice but harder to come by. I got mine off a 2007 FZ1.

As Mincehead says you need the ones with the bolts from the side as the pic. Not bolting from the end back towards the fork. I struggled with all that axial/radial stuff till I saw a pic and had the "a ha" moment.

Thanks v much Mincehead and Rubes. The picture helps. Got it now. Maybe I will look for silver. Presume they are the same calipers, but with a silver cover.

Widely believed the blue spots have a stainless steel set of caliper pistons..where the gold and silver versions have alloy with maybe a ceramic coating for electrolysis and weight saving.

I think you may be correct Alex, not had any in my hands for a wee while and the brain`s addled.

Silver and blue spots both have steel pistons.
They chose the coated alloy on the gold spots to aleviate binding.
Be interesting to see what style of piston they use in their radial pistons now.

When I was researching the Goldspots, the Radial version also used the same piston, from memory all the way up to the most current model. Theoretically, you should be able to use the Goldspot piston in any of the spot calipers, but it'd probably be cheaper just to get a second hand set of Goldspots.

The 100mm pitch axial gold spots only came out for 2 yrs on the R1 before they changed to radials but the silver spot axial calipers are still used on the FZ's , 600r's and XJR models.
So the goldies are a little harder to source to suit thd TRX.

Over here in the UK you can find them from XJR1300`s too.

Think also Yamaha T-Max 500 uses gold spots. Have mesaure them quick one and it is 80mm CC between the holes!

It does indeed! They`ll fit a TRX.

They sure look like gold spots on my old man's super tenere, too.

Just had a gander and YES, they are indeed!

There is also a set on my trx ..
Very happy with them as well.
Thanks
