I have a 2020 DCT non adventure model with approximately 8,000 km or 5,000 miles on it.
Some gravel, mostly highway use.
I clean and lube the chain frequently and after each ride.
I have used diesel fuel and WD-40 to clean the chain, then wipe it with a rag and then lube it with PJ-1 spray lube.
Upon inspection of the chain, I am seeing some rubber O rings that are broken and are separating from the chain. At how many kilometers or miles should this happen?
Anyone else experiencing this???
Thanks in advance

Probably caused by the solvents.

I have 20k on my chain. Give it some dupont lube every now and then. Orings are still good. I dont do sand and mud very often. Probably change chain and sprockets soon.

I second this, and as a diesel tugboat engineer by trade WD40 should be fine in most applications but diesel while being really good at cleaning things the petroleum distillates and additives in normal modern #1 and #2 diesel to keep it from turning to wax and freezing or gelling is hell on rubber o-rings and causes the rubber to swell an breakdown which is why chain specific cleaners were created and also why alot of diesel engine manufacturers and starting to use Viton and silicone orings instead of Buna-N rubber.if you are looking for a powerful cleaner a kin to brake clean but won't damage orings or plastic you can use electrical parts cleaner or QD contact cleaner . Also as a side note stay clear of wire brushes to clean chains only plastic or nylon brushes as the wire will also cut the rubber

Keep the rubber side down

Thank you for sharing your knowledge with me, I'm very grateful to you.
From now on, I'll simply use WD-40 for cleaning, and I have a nylon brush.
Wipe clean, then apply a spray lube.
Many thanks again.

No problem a light blast of compressed air also can do wonders for getting into the nooks and crannies

Compressed air will blow the crap, crud and cleaning solvent past or into the o-rings. The crud then acts as an abrasive and the rings don't last long.

Ahhh see thats why I made a point to say "LIGHT" blast of compressed air, just to get the small stuff and excess wd40 or whatever cleaner off so it doesn't fling everywhere as soon as you start riding

I just use a Grunge Brush to remove the crap and re-lube. I do use Motorex off-road lube.
Bret Tkacs made a nice video on chain maintenance - he uses diesel -
It is absolutely critical for chain tension to be sufficient. The AT Manual method is too tight. check this post and a few either side of it. https://advrider.com/f/threads/the-...owners-thread.1112644/page-1437#post-42242570
On main stand chain pin centre line 66mm from bottom of swing arm half-way between axle and sprocket.

It’s really not that tough. If you do feel compelled to clean the chain just use an old toothbrush with some WD40 before you wash the bike, then rinse clean while washing the bike. Ride around the block when finished washing to fling 99% of the water off the chain and to dry the brakes. lube the chain.

I have 18k miles on the OEM chain and have only done a few WD40 wipe downs of outer links and use Dupont chain lube once every tank. I ride lots of dirt and wash the bike every month or so or when it's super muddy. I commute daily also and ride in the rain. Very little maintenance and still doing well at over 17k miles. Don't overthink it.

Hmmm....compelled to clean the chain.
In my books, keeping the chain clean and lubed is prerequisite.
That is, if you want to have longevity of both chain and sprockets.
