    See if i can help clarify things for you...

    Depends on how many hours the barrels done and its current bore measurement/wear.

    "Generally" pistons are a B type when fitted from new which gives tight and best tolerances, they do also come in A,C,D SIZES which are incrimments of thousanths...

    Looks like Ktm supply size 1 "B Size "2" D

    Someone maybe able to confirm this Ktm system?

    Should get pin with piston kit but more important change the small end bearing about a tenner bud.

    Thanks for that Pwoiks confirmed what I thought...

    Hope the orange reps [Jon and Wege] are taking note vertex are ok but they used to use Mahle and were £150-£180 a shot but the best!!

    Just change more regular and be ok, look forward to getting out with you soon.
