How much were they ?

About £550 IIRC with rings for +1mm oversize. That was for SP pistons though, i believe the RR pistons have a different part number so you might wanna double check https://www.fowlersparts.co.uk/

Parts book is in the docs section

Racing it on the roads so they get stripped and checked, can run 1mm pistons legally
