    20 hasn't changed from 19, measured 20mm below from edge/top ,the gap should be .40mm on both rings.

    Thank you! I figured 20 is the same as previous years, just wanted to make sure.

    Thank you for the info. Good to know.
    I suspect it could be less than that and still be ok, as the age old rule of thumb has been about .004" per inch of bore diameter, which would put the 125 ring gap at about .008" (.2mm).
    Heck, new rings for a 300 have measured about .3mm since 2004 without a single issue reported here on KTMTalk.
