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.

only a guess bud ,but good advice there off walnut,would,ve thought your bike is still on standard piston and rings,their that good nowadays...i think ,ktm dealer,..standard

thanks for the info boys. new piston kit will be on the way shortly, then scream the tits off her time [You must be registered and logged in to see this image.]

Did you notice what piston there using as standard oe

should say inside the skirt area....??

it says vertex ktm on the skirt.

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.

wege had a skirt on today i think you;ve confused im walnut
