Here in Aust. at least the 530's have had more issues with cracking pistons than the 570's. The 570 piston is different and seems to hold up much better, I'm not aware of any 570 pistons breaking over the last 2 years, where as I know of several instances where 530 pistons have broken and now the KTM team routinely changes pistons to avoid breakage.

We have had 2 early production 2009 570 big ends go but none of later or more recent production runs. These 2 failures we had are the only ones reported to date in Aust. Again I know that the 530's seem to have this issue more frequently.

Of course all this depends on the rider and how the bike is ridden..........other 530's such as Jaybo's enjoy a long life with no issues

Amongst the EU Dakar rallye crowd there is a distinct preference for the older 525 RFS motor over the 530 motor due to reliability issues
