Apparently the R1 Gold Spot were the final incarnation of these type of calipers as the later ones use the same system, but are radial mounted.
The Pistons are similiar to Fazer 400 Brembos in that they have a black low friction coating. I replaced the seals on the 400 recently and whereas the caliper had some corrosion and the dust seals hard gone hard, the black coated pistons were completly corrosion free. I was able to scrape of the dirt build up off the pistons with ny finger nails. Something I could never do on the standard stainless pistons
My blue spots are in excellent condition, but I did notice that it was easier to push the pistons back on the Gold Spots than it was on my Blue Spots.
To answer the EBC disc question, I am very disappointed with them, :'( a waste of money,the OEMs were a far superior disc.
The only advantage they have over the OEM is that they are lighter.
I have always used EBC HH pads even with the OEM discs without any issues.
With the EBC discs when you park the bike wet over night the pads are rust seized in the morning. They are very poor when cold and worse when cold and wet. I have to apply the brake lightly to get them to heat up to work properly in cold and wet weather. I changed the pads thinking that there may have been contaminated from the running in process of the discs but the new ones were the same. They also make a strange whirring sound which took a while to get used to.
I would not recommend them to anybody who uses their bike in all weather. will change them for something else,if necessary OEM when I ave some spare cash.
