Something is wrong with your KTM. Check the runout of both sprockets/output shaft/rear axle. Also check chain alignment throughout the range of rear suspension travel.

The only snapped chain I have ever seen in person was on a KTM. The dealer had changed it about 500 miles before, so maybe they are a PITA to fit correctly?

F650 chains fail very quickly once they start to go. It's because BMW or Aprillia took a chain meant for a 250 twin and used it on a 650 single.

The difference with the MZ enclosed chain and a lot of the others is that it was designed on, not bodged together afterwards. If you don't get the tubes in the engine case grooves it fails. Assemble correctly once, leave it alone and it'll work for years. I'm surprised no one has designed a bike specific add on though. Modern adhesives should make it possible at add something like the MZ grooves to the back of any case.

That's interesting as one of the guys I met in southern Germany on this year's Elephant rally was stranded with a snapped chain on his F650. One of the side plates had snapped, the chain had opened up, jumped the front sprocket and taken out a chunk of engine casing. We wondered whether battery acid vapour was responsible as there didn't seem to be any significant wear on the rest of the chain or the sprockets but the failed side plate had a kind of fault line break in it.

The chain looked to be the same size as those on my XR600 and CCM600 so I wouldn't have thought it underspecced. It certainly hadn't been ridden hard.

Broken chain = 50 dollar fix - chains everywhere around the glob. Minutes to oil and adjust.
Broken shaft or blow final drive bearing = Hours of labor only if you didn't pack along your own bearing and U joints. Beyond that depending on the country, you could be stuck for a couple weeks.

3 reasons:
1: because the Scottoiler was invented
2: because DID-X and DID-Z ring chains were too
3: because there is a tool which undoes and re-does them up if needed- 150 grams of deliciousness / size of a 12 guage shell.
But you already knew all that!

It has been used twice Dazzer- and yes, I do look after all my kit; ACF-50 does a great job.
Ted- It's a....chain breaker! Don't you already have those at Chester BMW?

Agreed. Although I am not sure about the sizing of the chain, those fitted as OEM on the F650GS single cyl were pretty much rubbish - mine was replaced with Renthal sprockets complete with a new chain.
It goes for lots of manufacturers of course; stuff fitted as OEM is often purchased by the accountants, not the engineers.

Absolutely nothing wrong with the KTM. The bike is used almost exclusively for trail riding and probably only done about 800km on tarmac. The terrain can be very rocky and I've probably been unlucky - all 3 breaks have been broken side plates which have been repaired with rivet links, not at the roadside because I didn't have the parts with me at the time. I'm still using the original chain but did fit a non O ring chain for a while (whilst waiting for parts) which also broke.

Early failure of the shaft on my R100GS was probably due to a 30,000 mile trip around Africa 2 up with 95kg of luggage.

Apart from breakages the chain is quite easy to live with. I brush on chainsaw oil before every outing and hardly ever adjust it. I certainly wouldn't hesitate to take a chain drive bike on a long overland trip but I'm more likely to take the R100GS after appropriate servicing, as mention before, just because it's my favourite

In 1000000000004 miles (ish) of riding all types of bikes over all types of terrain, I have never had a chain snap.

I've seen snapped chains. It's always poor or incorrect fitment. Usually where someone hasn't peaned the link properly or peened it so tight that the chain can't flex properly.

It happens when you abuse it too (Like anything). Running badly worn sprockets can do it or having a rediculously tight/loose set up.

If you fit the right chain properly and replace your chain/sprockets when they need replacing then you won't ever have a chain snap.

I'm a fan of chains for all the reasons that people have listed. But they do need some thought on long trips.

My rear sprocket after 26,000km and no I hadn't taken a spare - and just because a bike is common at home it doesbn't mean it is at your destination. This is from a KLR 650- common as muck in Australia, but harder to find in Europe

An individual case, either caused by a user error, or even a manufacturing defect, can always be possible. But for me, chains snapping is not a valid argument here. They just don´t do that under normal circumstances.

I'm not disagreeing with either of you. There is definately no element of incorrect fitment or user error in this situation and I'm happy to put it down to bad luck. I can't think of anyway in which the user could aggrevate the failure of a sideplate. I get good use out of chains and sprockets but don't run them until they are worn out.

All I am trying to point out is that chains can be unreliable as can shafts but it is feasible to carry a complete replacement rear transmission system with a chain drive but this would be less practical with a shaft. With a shaft there is potentially a lot more to go wrong.

Don't find yourself sitting in the middle of a desert somewhere saying to yourself "chains snapping is not a valid argument here. They just don´t do that under normal circumstances" when you don't have a spare, because in my experience it can happen.
