    NSR250 MC18 Piston & Ring Set

    reviewer: Revspin

    (3 Stars) - Monday, November 11, 2019
    One of the Pistons ordered did not match my original order as some of the Pistons were not in stock (there was very LTD Stock as parts are now obsolete), although they appeared to be on WEB Site.

    A superseded Piston was put in its place, but, this didn't match the other Pistons ordered.

    However, a quick ring to CMS and all was sorted.
