The 450EXCs also suffer from broken pistons in the same conditions with similar piston design to the 530. Once again it's actually pretty rare.

I'd guess the "sample size" of comparisons between 530 and 570 are a little biased. I really don't believe the 530s have big end failures "more frequently" than 570s if the sample size of comparisons were the same. There's a heck of a lot of 530s out there but relatively few 570s. I've also only heard of terminal problems in Rallying - ditto only commented with respect to a rallye racing application not in enduro and trail riding where the 530 and 570 are designed to be used.

I kinda hope the 450RR piston is like the Berg one. Just exudes strength and confidence.
the 450RR piston presumably will be similar to if not same as the 450SX quad piston which I havent seen to comment on
