A failure is a failure. Things break. Just looking at this from the outside it screams "over revving" in nature of the failure.
KTM is the best of the bunch to back up their machines. Good luck

Hey if this happened to me and KTM took care of it for me I don't think I'd ever be buying anything other than a KTM. It's probably worth it for them to take the blow and have the guy continue to buy KTMs.

Must be a home schooler, never said sit on line at idle, just said to rev it to the meat of the power which isn't were the rev limiter is and I was saying that a dyno does not duplicate real world and has very little load, hence when someone said that a dyno is under load I made the point that a dyno is not in sand, or on a hill, or a take off ten feet out of a corner, a dyno can not duplicate real world use.

Just clownin around, wasn't calling you out like you're an idiot. This thread has been interesting now matter how you slice it.

Dyno talk is the worst though. Like when a dyno result shows 48 hp and someone is like "wtf, someone else dyno'd the bike at 51hp, who's lying!" Meanwhile the dynos are different, different day, different humidity,etc...

You must've missed where I said launch control lowers the Rev limiter to the meat of power band.

I'm guessing that people assume that "launch control" just lets the bike rev to the max limit like it would with no launch control...

I agree with you, I used to tell people they don't have a dyno world championship. We would test every pipe on the market and I always thought the Dr. D was the best pipe in the meat where you use it, and of course everyone would say ya but the so and so pipe did this on the dyno. Also I am aware that the launch control is supposed to rev it to the best spot in the rpm but I don't believe the factory has that ability.

So is KTM covering this or not?

Enquiring minds would like to know... maybe I missed it, if I did many apologies!

Launch control is a feature that is designed to used at WOT. Bounce "at the meat of power" how much you want!

Okay, not really but KTM wouldn't implement that feature if it was likely to blow up your bike after only 40hrs.

Have you ever dyno'd a bike that was rolling around a track? Just to see what the bike did in real riding conditions?

Usually when ktms break the owners lie and say it didn't break. this is surprising to see him actually post pics and proof of this. Anyone who says Ktm will pay is crazy. This guy should also post the receipt saying "no charge"
We've had ktm warrantee several race bikes.

A few frames and transmissions on the new 125s

And a complete motor on a 15.5 250sxf.

The owner of our shop has an 11 350 with maybe 200-300 hours on a stock engine.

For the most part ktm stands by their product.

I have not, that would be hard to do, lol. But I have tested with the Yamaha telemetry equipment extensively and have a ton of stats on how much throttle and how a bike is performing on the track in real world conditions with a variety of aftermarket parts and exhaust systems.

I need to clear something up quick. At no point did I ever claim this is the fault of KTM and that they should cover it. I posted this asking if anyone had an idea as to what would have caused it. There is no reason for myself or my friend to think KTM has to cover this. If they do, great. If they don’t, it’ll be fixed and ready to go next year.

I have used instrumentation on vehicles that measures in cylinder pressure and torque at the driveshaft, so engine output can easily be calculated while driving down the road. I would be surprised if the calibration engineers from the various OEM dirtbike manufacturers don't use something similar. At the very least it is helpful for spark mapping.

Very good for KTM to cover the repair, but if it happened to me, I'd buy elsewhere. Never had any other mfg's bike do this to me and I'd say the owner is extremely lucky that he was stationary when it failed.

You don't believe the factory has that ability? It's not like they couldn't determine that max torque occurs at X rpm, and set the launch control rev limit to that RPM.....been going on in drag racing forever. Ever hear of a stutterbox? Also, true, a dyno doesn't impart a "real world" load, but to say that it doesn't load the engine is disingenuous at best. I'm thinking it takes a bit of effort to accelerate a 1000lb (or more) drum to as high as the machine will rev in top gear...

Going way back here. Back in 83 got a RM125 from a back door Suzuki sponsorship out of a Suzuki shop. In practice of third race broke the skirt off the piston. The rod ruined the cylinder, cases and crank. The bike was 2 weeks old. The dealer contacted Suzuki about the situation, without hesitation they were told that it was a race bike and had no warranty! Lucky my ride gave me parts at dealer cost. If KTM stands by this you are very lucky.

Great. I bet I know who rebuilds it if they don't cover it!

KTM is very good with their warranty. I had a rocker arm that completely snapped in my FC450 at 7.1 hours. KTM sent a brand new engine for absolutely nothing.
