R65..

I am now working on the front brakes and have stripped down the
calipers.
All four pistons have corrosion on them, near the edge; the new seals
will be making contact below these areas of corrosion.

Will it be feasible to reuse these pistons as they are?

A few pictures are at:

I'd reuse them.

I'd polish up the pistons and reuse them, assuming the bores aren't
beyond hope. What do the caliper bores look like?

The bores look OK.

I have compromised and bought 2 new ss ones, these will replace two
of the original pistons (the two with the most corrosion).

How come pistons are so expensive on motorcycles, are they just
as dear for cars?

At a guess, there are many many more cars sold than bikes...
