One of my Pistons on the rear caliper has been binding for some time. Picked up some seals today to strip and rebuild but both pistons are corroded in parts and I'd like to replace them.

From my novice search I can't seem to find replacements. Are these not available? I find it bizarre that you can buy everything else for the caliper but no Pistons?

2006 1200GSA (non ABS)
 
They only have seals for rear 1200GS. It appears they're unobtanium. Brought a 2nd hand caliper of the bay so hopefully the pistons are good in that.

I find it a bit odd that you can't buy replacement pistons for such a bike.
 
Yes,

Got seals and fitting kit there today. Didn't ask about pistons as I'd hoped mine were OK. One corroded and far from perfect, the other I scored taking out. Have searched extensively and cannot find piston kit for rear calliper.
 
You can buy seals on their own or a piston and seal kit but not pistons only for the 1200.
The whole kit is nearly £60!!
Hope your second hand unit works.
