My BMW f650GS was great when it ran. When it ran.

I would pose the dropped valve question in the garage forum. I'm not sure that I can give you an informed answer.
I was thinking that an aftermarket exhaust with no changes to mixture could lead to an excessively lean condition, overheating the combustion chamber leading to a burnt piston. The event you described sounded more like a dropped valve to me, so I guess not.

My 1977 R100S had 80,000 miles on it when I bought it.
Never gave me trouble.
I'm sad to hear what their modern boxer is doing.

I hope you're wrong too. That would be a bunch of crap, especially because this was the go-to recommended system for the bike, installed by the dealer. And besides... what the hell happened with my brothers bike then? That was bone stock.
Anyway, it will all come down to the diagnosis. It will have to be somehow directly linked to the exhaust mod for them to even argue that.
If they don't cover it for whatever reason, which is a real possibility, I will make it my second job to promote this event across the web, including a dedicated website, and make it clear that BMW feels there is nothing wrong with an $18k bike self-destructing at 11k miles under normal use.
Or... I'll promote how well BMW NA handled the situation. It's their choice.

Tonight we ride
11k miles and a blown motor...wow. Fingers crossed that they make it right.

My R100RT (airhead) is as reliable as an axe. Had it for 10 years, and essentially, all I've ever done is replace tires, change lubricants (spline lube, included) and adjust the valves.
The problems started with the single sided swingarms in the last of the airheads, and the K bikes. As each new model generation comes into being, a new set of "issues" arrives for owners to worry about.

My thoughts:
- used bike, yes? I conjure that from your 1st post. Perhaps previous owner abused it? Too many revs, bad break-in period? Perhaps a demo bike by BMW dealership and testers effed it up?
- applies to you or previous owner: incorrect oil type used, engine ran when cold?
- on the gasoline thoughts.. I'd be damn surprised if modern engine building gets so effed up by regular vs super gasoline.
Those were just thoughts.

Performance improvements are expected by consumers at a much faster rate these days, and so are other "features".
So development is pushed harder to provide more, with less time for testing, and less concern by management if there is the possibility of a latent issue, because their bonus is based on getting the product to market on time, not with perfection.
All this would work out just fine if they honored the warranty in every case, but the beancounters aren't satisfied with ruining the product itself, oh no, they will only be happy when all of the customers have left as well.
For their part, customers have unrealistic expectations...everyone wants a Ferrari with the maintenance of a Honda...
I hope BMW comes through and makes the OP happy with their attention to this case.

Some people think that a rough break in ensures a long life of high performance.
People have specifically theorized that those "demo" bike motors may end up being the best ones, because people leaned on them a bit when they were breaking in.
Not tried it myself, but the next new motor I get will not be babied much at all for it's break in.
Anyone have any anecdotal stories?

Detonation
Lots of bikes out there, including BMW's, require high octane fuel. That need can be amplified by leaner mixture.

- Yes, used bike. Although, I bought from someone I knew from high school. I researched the bike through both dealers he used. Both gave glowing endorsements for both the bike and the owner. He was also a 2-BMW owner, with a 1200 GS also in his garage (for what it's worth).
- I used only BMW-brand oil, purchased from the dealer. The previous owner stated he did the same and again, the dealer confirmed.
- Engine ran when cold??? Kinda hard not to run an engine when cold, but I am assuming you mean run heard when cold. I was about 20 minutes into the ride when this happened. The bike takes only about 7 minutes to reach operating temp, according to the gauge at least. I have owned many bikes, many high-performance cars, have done many track days on 2 and 4 wheels... I am pretty conscious of that stuff.
All good thoughts, though. Thanks.

IIRC BMW did over a 120,000 hours of testing the new S1000RR motor before putting it into production. I have no clue regarding other models.

Going into a new segment of the market it's very important to make a good impression.
As opposed to a segment of the market where everyone assumes you are the top dog, and the one to beat.
Flying Hun mentioned the detonation possibility...does anyone know if BMW bikes have knock sensors? I know modern cars will protect themselves from poor quality gas (Also you can pull a knock sensor off an old saab and use it to tune your homebuilt turbo car to the limit for less $$ than a J&S Safeguard...) but I dunno if any FI bikes have taken that step.

I'm finally at the point in my life where BMW motorcycles seem interesting and kinda exciting but the people I know that have owned them in the last couple years always end up having major issues. Kinda takes the bloom off the rose and looks like I'll stick with my other Euro-weenie marks like KTM and Ducati.

Well, they do come with 3 year warranties, if that's any consolation.
Very curious to see how BMW treats the OP; if they step up to the plate that will be a big
for BMW in my eyes.

I start it, roll it out of the garage and proceed to ride at low RPM's until the bike is warmed.
