Happened to me once with my 748R racebike. And have seen that happening several times. I mean the real cause.
To me with rear brake. Race footpegs had been recently installed. But apparently brake lever was in a position that reservoir hole was closed in master cylinder. Some laps, brake fluid expansion and rear brake caught in fire and jammed the rear wheel.
Once I saw one guy making a front flip at the end oh fast main straight at 240kmh. Totalled his R1 there. In previous weekend he had dropped his bike at the pit on to the right side. Front brake lever was a bit bend, but he thought it was just the end of it. But apparently in a way that it also blocked the reservoir hole and jammed front wheel.
And I personally have seen several cases like this, betting my money in this case resulting hub overheating and melting spokes.
