Yeah, I don't think we're going to be finding out any time soon. The parent bike for our engine is the 1992-1999 CBR900RR; there is a documented example of a pretty badly beat up 1992 cranking out 325,000 miles and despite looking like hell it was still going when last heard from (per a 90s article in Sport Rider). None of the (patched) plastics matched any more due to the multitude of drops over the years, it'd gone through some stators and it'd had a minor frame crack rewelded - but it was still going on the original engine with no evident sign of performance reduction or engine wear.
You are going to get bored with the 919 long before it gets close to wearing out the engine. Long, long, long before. So don't count on it wearing out so you can use that as an excuse to get another bike - because it's basically not going to happen. After all, it's a Honda inline four.
In thirty years, most of our 919s will probably still be around and most of the contemporary competition will have long since succumbed to engine failure.
