On the ZXR, the only bit that really sticks out is the stator cover and thats not really a biggie.
I can't really say what might be damaged cause I haven't really looked at the BMer engine up close and studied its internals. I guess I would expect the rocker cover to get damaged. I am not sure how costly that is to repair. If BMW bikes are anything like the cars, I'd say F-ing expensive.
