    85 atc 250R front caliaper pistons question

    I thought it was not recommended to use the composite pistons. Is there a part number to cross it to some steel ones? Mine are tight without the seals in. Thanks

    Personally I prefer the composite ones. No corrosion to worry about. I have composites in both Rs and no issues.
