I've changed about 1000 tires now. Just changed my first KTM 1090 wheel with the exact same setup that I'd never seen before. I also thought the gasket was glued on somehow. Very interesting how it seals with a lip and another gasket to seal all the spoke nipples. Now I can understand why some of the riders are modifying the wheel so they can fit a tube inside, which requires drilling a smaller (8mm) hole for the center mounted valve stem on the tube . The hole on the wheel for the TPMS is 14mm and it's offset 25mm from center, not tube compatiable. Great video! Thanks for taking the time to make and share with others
The first layer (the one on the directly on the rim) is there to cushion against the screws when they poke inside. I don't know how many realize this but in certain conditions (some rather extreme) a screw head might "lift" about 4 to 5 mm. A trick that might work to see leaks on the membrane is to coat it with talcum powder, pressurize an used tire slightly above norm until the hissing (and or loss of pressure) is observed. When removed the first layer will show tiny spots of talcum where the holes are. I say might, because i've only done this once and it only worked well with bigger cuts, still something that i would of had missed and blamed on the lip seal or the tire itself.
Thanks man, i tried the small patches too for the "possible tiny invisible holes" but its still leaking bubbles at all the spokes when i use the garden hose... i even tried gaffer tape carefully applied above rubber gasket but still leaks. I ordered new rubber gasket and rim tapes and will change in a few days. Fingers crossed. Nobody likes to be motorcycle grounded!
If you spread glass cleaner, the seal band will get into the groove A LOT easier. For some reason I don't know it's easier for me to sit the wheel lifting it vertically instead of from behind. Thanks for sharing.
Great video. Changed my first tire on my new 1290 super adventure R and of course I poked a hole in the rubber gasket and was leaking air through the spokes. I wanted to punch myself in the face. I ordered one and can't wait to put those grooves into the rim. That looks like so much fun. And of course fight with putting the tire back on. I will never change another ktm rear tire unless I've got a gun stuck to my head
ktm suggests to change the gasket every 5 years. do you know if you need to change the inner band as well (the glued one)? or just the outer gasked with the lip?
JoeJoe Moto Good idea on the flyscreen roller! If you want to run a tube you have to drill a hole in the rim since the standard valve is offset. I dont see the benefit of a tube anyway. You can easily plug tubeless and/or run some slime. A tube means you need rimlocks and you have to remove the rubber to fix a flat.
OK question: Would it be worth adding another rim tape above the rubber gasket to protect it from frequent tire changes? Seems like it would fit alright
I did it yesterday. Works beautifully. I kept the old gasket, cut the molded clip-on sides and around the TPMS, added it to my rim, popped-in a new tire and Voila! nice and tight DUAL LAYER protection
Put the tire with wheel into a tub of water. If you are losing air at a spoke you will clearly see it. Buy a tub the size of the tire diameter at Walmart or any box store.
I was wondering how KTM mounted tubeless tires on spoked RIMS ? ..., I thought it would be something like this; www.bartubeless.it/en ..., where you could simply repair holes (or replace spokes) with their Bartubeless supplied RESIN
ChopsAU No. To run tubes you need to redrill these rims because they use an offset valve and you need rimlocks. Tubeless is better. Its easier to patch on the road to.
MessyOg It sits in the corner waiting patiently for me to get some spare time to do its rebuild. It will run again, but ive spent the last 18 months doing some reasonably extensive house renovations. Only an outside deck left to go.
it only leaked once on mine. and it was not the bikes fault. i changed tyres and the mechanic probably pinched the gasked at one point, and it was not seated in the groove. pushed it back with my finger and the issue was gone. maybe check that next time you remove the tyres. it was really hard to spot it, you need to look for it from very close

You can get tubes with offset valves now. Motoz and Dunlop both make one.
Yeah, it's "interesting" until you poke a hole in it like I did. Then it becomes "Jesus freaking Christ!".
Thanks, I just bought an 1190r. Your videos have been the inspiration and valuable insights
Excellent help, you saved me untold frustration replacing the wheel
Also, the careful cleanliness of the groove it's a must.
The spacer holder pointer was pure gold.

Mate greetings from Japan! That tip about the rear wheel install is worth cutting the vid and posting as a tip by itself! Cheers.
Thanks for the video. I've got a 1290 SA and was curious how internal sealing worked.
Just had muy tires changed and I'm leaking out a spoke on my 1290 SAR. Thanks for making the video, saving my ass here.

thanks a bunch nerb1. did the same with my ham hands changing tires and nicked the bloody membrane. thanks again for your vids
It was you! I was wondering why my rear sumo tyre keeps losing air, it was after your handy work!!
Ausmodica That was not from a tyre lever... that was a knife.
Everything changed and no more problems. But rim tape from KTM is ridiculously expensive. Check out the idea above. Thoughts?
I can see how the 'Lip' could be handy.
Use your foot/toe under the tyre to lift the wheel in place, or a lever.
Nice one with the Leak...Doh!
>:)
My 1190 Adventure R, a toxic relationship I cannot remove myself from.
Man thats cool, intresting setup wonder if we can fit them rims to non ktm's
cool. always interesting seeing how these things go together. Cheers for sharing
Mate ... Fantastic ... sorry you had some drama's... but a worth while clip.
ktm suggests to change the gasket every 5 years. do you know if you need to change the inner band as well (the glued one)? or just the outer gasked with the lip?
I dont know, but I wouldnt think the glued one is replaceable. I suspect its the rubber one only.
@@Nerb1 The glued one is replaceable and is called the Felgenband.
Thank you Nerb for posting another very helpful video :-)
Had the same problem when I put my heidenau's on...fixed it with 2 bicycle patches.
Do many people run a tube in the 1190s? Also, I would have tried using a flyscreen bead roller to get the rim gasket seated.
JoeJoe Moto Good idea on the flyscreen roller! If you want to run a tube you have to drill a hole in the rim since the standard valve is offset. I dont see the benefit of a tube anyway. You can easily plug tubeless and/or run some slime. A tube means you need rimlocks and you have to remove the rubber to fix a flat.
JoeJoe Moto I run a tube up front. Had to grind a few mm off the 'nut' to make it fit properly.
Nerb1 Yeah, I guess on the big adventure bikes you wouldn't be running crazy low pressures like I do on my bike.
Thanks mate, a very good informative vid, good work 👍
Nicely done and explained my friend!
OK question: Would it be worth adding another rim tape above the rubber gasket to protect it from frequent tire changes? Seems like it would fit alright
Thats a good idea. I might do that on the next change
Or even a slice of the old rubber gasket ;-) slightly narrower to prevent rubbing against sides
I did it yesterday. Works beautifully. I kept the old gasket, cut the molded clip-on sides and around the TPMS, added it to my rim, popped-in a new tire and Voila! nice and tight DUAL LAYER protection
I'm gonna put 7 or 8 layers on mine. Once you poke a hole in one, you start getting crazy ideas as how to make it not happen again

Any link or name where to get thit rubber please? Thanks
I got an original from my local KTM dealer.
Good video mate.
Hmm, didn't realize the 1190 ran tubeless tires. Do you run tubes for dirt?
ChopsAU No. To run tubes you need to redrill these rims because they use an offset valve and you need rimlocks. Tubeless is better. Its easier to patch on the road to.
Yes, tubeless is the go for the road, but I thought that tubed tyres were better for offroad due to a stiffer side wall?
Excellent!!
Come on mate, no more hiccups. We don't want Tom looking for a new mechanic... or do we? :)
***** I keep sabotaging his bike to slow him down.... does that really count as a mechanic?
While I sit here and eat tea at 10:00 pm, I gotta ask Nerb, what ever happened to the husky Supermoto?
MessyOg It sits in the corner waiting patiently for me to get some spare time to do its rebuild. It will run again, but ive spent the last 18 months doing some reasonably extensive house renovations. Only an outside deck left to go.
the spoke wheels are a really bad joke they always leak , this is my only complaint with my KTM ,
So.... Your bike has rubber inside the tyres to stop air getting out?
Isn't a tube just some rubber inside the tyres to stop the air getting out?
lel
its really bad , fillup back With 45 psi next day its 24psi ,
That's 24 psi more than I had
its a very bad system allways leaks ,thats the only reason for me to never buy that again
it only leaked once on mine. and it was not the bikes fault. i changed tyres and the mechanic probably pinched the gasked at one point, and it was not seated in the groove. pushed it back with my finger and the issue was gone. maybe check that next time you remove the tyres. it was really hard to spot it, you need to look for it from very close
