See that quite often on all brands of bikes at the shop. There is a gasket in the valve stem that can leak. Usually a small turn on the stem nut sorts it.
Sounds like a tire may need to come off to tighten. I checked the spokes tonight and no leaking found.The rubber seal on the inside of the rim has a steel grommet that the valve stem passes through, then it pokes through the rim. The rubber collar on the valve stem has to keep the air from migrating around the steel grommet.
Even blown up on my computer it's still not a helpful drawing. But wow, list price on a valve stem is $44.KTM OEM Parts, KTM World

Part #15. I can't blow it up enough on my phone to know if this is useful
Concur. Put a crank or two on that nut and call it square.Assuming the grommet you mentioned goes around the rubber bottom piece, it seems like lifting and tightening may be the best approach before taking off the tire.
I sent a note to the dealer this evening. Expect to have their thoughts tomorrow.
I know. Didn't really think it was a KTM problem. My guess is it's not even a KTM part.See that quite often on all brands of bikes at the shop. There is a gasket in the valve stem that can leak. Usually a small turn on the stem nut sorts it.

Thank you. These two posts really helped me have a better understanding of what I was facing.View attachment 99520
This is what you're working with (minus the TPMS sensor on the 890 I'd suspect). That rubber ring below the threads keeps in the air in and may need to be tensioned by the threaded collar above it.
That's pretty much what the service manager told me, too. Although there was some level of doubt expressed on if it would work. I managed to add about 1/4 turn or maybe a bit more. So far, it looks like it's holding air again.Concur. Put a crank or two on that nut and call it square.
It seems that not... reliability is related to the possibility or not of an event occurring... and if that event occurs (possibility 1)... you would have to see what the probability of it occurring is by measuring it in %... you could not relate the reliability of a brand, due to the failure of a "common system"... the common system would be the spring CCT, with an anti-rebound system by hydraulic pressure of the motor oil... that system tends to fail (regardless of the brand where it is placed )…..that is to say that what is not very reliable is that systemI have KTM dirt bikes, a 690 duke, and my daughter has a 790 duke. Only real problem with any of them is that the 790 has a very weak front turn signal mount where the plastic is too weak to support the turn signal at high speeds. at high speeds, the turn signal oscillates, and a crack starts at a sharp corner. Just poor design - summer intern?
I replaced the mount plastic once, and it cracked again. the fix? 1. use of electrical tape and a stiffening bar to reduce movement of the turn signal. 2. purchased another plastic mount (~$100), so if the electrical tape fix doesn't work, the new piece will go on with a stiffening bar and electrical tape. However, the tape and bar stiffen the assembly quite a bit, so i don't think it will be a problem again.
My 690 is a 2014, and the the 790 is a 2019 purchased in December of 2018. No complaints at all with KTM reliability. I had to replace the CCT in the super 10 at 25k miles - one could argue that that the S-10 is less reliable than the KTMs.
I hear the windscreens are due in very soon. Make some room in the garage.Glad you are enjoying the new ride. Had my Tiger in for service today and my dealer has a new 23 890 on the floor. Without windscreen of course. I am for now resisting temptation to add the 890 back into my stable. I predict there will be one in there probably next year. ....or sooner.... Dangit.
That's part of what I figured out watching the videos this afternoon. By keeping within the break-in RPMs I'm missing the range where everyone starts laughing their heads off. Can't wait to get those remaining 370 miles behind me.Sat on the new 890 Adventure today. Fits well I think the Norden may be a goner.
On my '21 890 in Rally mode it's hard to leave a stop sign without spinning the rear wheel. The bike spins up rpm very quickly. The best part of the party is between 6000-8000 rpm. Its different than the 1290, you'll sort it out.
Definitely wrong about this assessment. I took the bike to the twistiest roads in the area. Stuff I ride all the time and know every curve and anticipated hazard. Time and time again, the 890 shocked me. Forget 19 inch vs 21 inch. The 890 is NOT a low drama bike in the twisties. Even with 50/50 tires and RPMs under 6.5K, it is an astonishingly good/outstanding twisty road weapon. I had a blast riding my favorite local roads. I got home and told DM, "If I were leading on the SAS, I'm not sure I could lose me on the 890." Once it's broken in and unleashed...what does that mean?I'm impressed with the complete and total lack of drama when the road throws you a curve, or two...or ten.
