KTM 1290 SUPERDUKE R - MEET THE WORST ABUSE IMAGINED, Engine Reliability Review

[@Panzerlang]

Another superb video from Eric and one that provides a lot of reassurance for owners of a much maligned bike. If that's how well it holds up to 8k miles of hard track use I don't think us street hooners have much to fear (I almost never red-line mine, there's simply no need for it). :)

[@MichaelKobler-yu6fy]

I can assure you that these bearings have not spun in the housing. You'd see tangential marks, not only discolourations. Secondly, the oil bore is supposedly aligned with an oil channel, an incidental misalignment would have caused an amount of damage that you'd have seen. Overall, pretty normal bearing wear given the use case, nothing to worry about.

Interesting that the rod bearing(s) had spun but you didn't know it... I wonder why. Maybe an August race at Thunderhill, super hot and thin oil and you got a little metal on metal contact? Appreciate the video.

[@superduked33]

One responder here suggested very kindly and gently (not) that the bearings had not spun at all. Guy questioned whether I had ever even seen a spun bearing. Said the case would have been destroyed. Another user suggested the oil had overheated, which I can see happening - especially since this bike had so much use before me. ...For the record the only thing I'm interested in spinning is the rear tire.

[@Eric-Marsh]

That was my take. I used to machine and build engines for a living and those don't look like they spun. If they had then it would be time for one or more new rods and probably a crank, though that bluing on the crank is unusual. The bearings are pretty well beat up though. Perhaps a higher viscosity oil might be helpful. The crud in the oil pump may have come from the bearings.

[@superduked33]

@@Eric-Marsh thank you Eric. Sincere appreciation for your experience and opinion

[@holmes1956O]

In the video he said it was a main bearing that spun not a rod bearing. If you pay attention to the video you can see the mains are plain bearing like the rods. I am assuming that spun he meant maybe a quarter or half turn not several times around.

[@Eric-Marsh]

@@holmes1956O I guess I missed that. The mains look a lot like a cam bearing in an American auto engine. Generally cam bearings need to have the the hole that feeds oil to the bearing aligned with a hole in the block though sometimes there's just a grove in the block that makes the alignment irrelevant. In any case a spun bearing is usually a major problem.

[@dawn-moon]

On my 1290 Gen 1, Special edition, the stock clutch plates were "worn" after only 15k kilometers of street/wheelie use, and I almost never used the clutch lever to pull a wheelie. The plates didn't measure problematic, and I only had the problem in 3rd gear, so the dealer upgraded the clutch springs on my request. When that didn't help either, I bought a new clutch pack from Barnett in the US. Problem gone. :) I'm surprised to see the good state of your clutch. KTM must have learned then I guess :)

How often did you change your oil & other type of fluids when riding this hard? I'd imagine it's almost after every race / track day?

[@superduked33]

Good question. On average I changed oil prior to this rebuild on this motor after every third weekend. Now I have changed that to every other weekend. Also now I changed to Motul oil. I pitted with a guy who runs superbike-built Ducatis two rounds ago. His engine builder, Brian Sharp of Boulder Ducati, gave him specific instructions to change oil every other weekend or rebuild the motor by summer. ...That made an impression

[@Near2Future]

@@superduked33 Ah, much less frequent then I orignally thought. I knew it had to be pretty often going at it that hard & oil is cheap. Compared to an engine / parts anyways. So even with these frequent oil changes are you still having to rebuild the engine every other season? Or is it more down to how often you race / go a track day? It'll be intresting to know how the engine holds up now you're changing it a little more frequently. I'd imagine not very much as tbh to the duke. There wasn't much damage at all, which I am very surprised at with how hard. You go on track / race days. definitely gave me more faith in KTM engine side of things. Electronic wise meh not so much, i've had my share of issues. Little things but very annoying lol

Wonder why KTM can't seem to get the reliability out of their 790 and 890 motors like this 1290 has had? Mind you, I don't agree that the crank bearings should spin at ANY TIME regardless of being raced or not. That's a sign that lubrication has broken down (oil pressure or oil condition or both) to the point where the crankshaft has made contact with the bearing sleeve, and by friction grabbed it and spun it in the engine casting.

With regard to transmission issues re gen1 and early gen2 1290 SDR and GT with some having destroyed transmissions (broken teeth on 5th, 6th IIRC); did any explanation surface?

[@superduked33]

Define "fear"... :-). KTM's reliability track record with me is pretty outstanding. Gen1 had some issues with electronic shifting - which I responded to by forcing it to work. That caused some problems for sure. But most of that was me refusing to listen to them telling me NOT to use electronic shifters. Anyway they fixed that situation since the Gen2 and I haven't had a problem since. So "fear"? Not so much fear. But there are thoughts, anytime something new comes out from anyone. It's a good question that I won't be able to answer accurately until I ride the living hell out of one.

The LC8 is a great engine. I have the 1050 cc version in my 1090 Adventure R. It's a workhorse.

1090R awsome...

Do you run stock handle bars?

[@superduked33]

I do, on the Gen3. But I used Spiegler drag bars on previous models. Currently considering bars with half the left as stock with slightly more bend. Haven't found one, yet..

[@rlovell383]

"spun bearings"? I'm sorry but those look like normal wear and tear. The case would have been wrecked if they spun, and you would have lost oil pressure. I'd say your engine held up very well!

[@superduked33]

Yes, as you and other experts have pointed out, these bearings did not actually spin. It's still not clear why they looked so different on the backside but I agree they did not spin. Thanks for helping make that clear.

[@helgejohan3604]

What type of oil was used🔥?

[@superduked33]

Motorex factory spec

[@jpmorgen5726]

Seems like KTM's typically have some small, relatively minor things that have problems: water pumps, cam chain tensioners...too bad.

[@superduked33]

Cam chain tensioners are an issue. Solvable though. That video is on the board soon

i really wanted to buy super duke 1.0 sir should i or not i have worst experiance with 690

[@superduked33]

I have beat the living hell out of this motor and it just lasts and lasts. I don't know too much about the 690. But the 1290 is solid

@@superduked33 thank you sir i will buy it after i sold my zx6r 2019

[@reecechapman251]

they still got problems with their tensioners... killed my rc 390 engine at 10k miles :/

[@superduked33]

I agree with you. I've had them fail on me twice. Replacing with better tensioners is a smart move

Do u run race fuel?

[@superduked33]

I run T4 (unleaded for O2 sensors) for intense races, otherwise I use pump gas

Looks like over heating on the main bearings. Burned on oil.

[@superduked33]

Thanks. Although I've never seen high temps. Perhaps it happened prior to my ownership. I was actually amazed that even in 105 degree heat racing in the desert in a 20 lap race the temp of the motor was not hot. ....Although by "temp" I am referring to coolant. Perhaps I should be monitoring oil temps too, which are deeper in the menu. I also talked with one of the engine builders of the Daytona 200 winning team this year. I asked him about oils, showed him the pic of the bearings, told him I'm using Motorex. He suggested one problem with Motorex is it does not say Motul on the label..

[@Gsnus]

Sorry to say: Youre describing the chain tensioner completely wrong. releasing the tensioner wrong, can destroy it.

[@Glorious117]

Do you think this is the same with gen 1 and 2 ?

[@superduked33]

As far as the engines reliability and resistance to wear, yes I do. That was my gen2 experience as well. Wore like iron. Ironically I did actually skip a cam chain tooth on my gen 2, but that was due to an engine builder leaving a valve shim in the motor after a “superbike build failure” (not Alex). The shim blocked the oil port to the rear cylinder tensioner supply and caused it to fail. Coincidentally though right?

[@dawn-moon]

Just FYI, the tensioners can be seen very well in this video of a cut open version of an LC8 : kzbin.info/www/bejne/nHrKo3xphdKpbdksi=lDUu7S4CsI64G-hJ

[@gianmarcocalabrese1407]

so it is possible to go beyond its limit with a superduke 1290

[@superduked33]

I’m sure it’s possible to go beyond any bikes limit. I guess the trick is how far beyond, how long beyond, and how often beyond
