Having said that I have about 45hrs on my 2017 and have had no issue, I have not seen or heard of this anywhere other than on Vital which tells me it is not as common as Vital make out. I've probably seen 3 complaints posted here in total.
What did you think the plastic piece you got with the bike was for?
Rider/mechanic error
I had issues with my 16.5 but that was the first gen AER 48 fork. Once i got the updated x seal i never had any issues with it.
But call your KTM dealer. They will sort it out in no time.
I know It's annoying, but a quick fix, and the dealer will likely take care of it.
Great forks, great bike.
Remove the airbbleeding screws from both legs and pump it up to 17 bar and it normally goes back.
Without removing the bleeding screws it is almost impossible to fix it at track.
Pit Row
You must use a wheel chalk when tying down the Bike. What happens is you can compress the forks to the point where all the air goes to the rebound side of the forks. When this happens no matter how much air you put in the fork it will not fully extend because of the air trapped in the rebound side of the fork. This can happen very easily the colder it is
That’s a bummer! I thought that stuff was taken care of and had no idea it was still happening.
