On the EBR-website specified chain size 520. This is a typographical error or actually for such a powerful motor enough so flimsy chain?
What can you say about the stock chain? Do at least 10000 miles?

Flimsy? 520 is sufficient even for MotoGP. This bike is all about watching weights.

Honda CBR954RR - torque 105 Nm, chain size 530
Aprilia Dorsoduro 1200 - torque 115 Nm, chain size 525
EBR 1190 RX - torque 138 Nm, chain size 520
How can understand this? The more torque - the more narrow chain?
Chain and sprokets of motoGP prototypes have resource for one weekend. It is important to weight, not a resource.

Zviadi the chain Pitch is 520, what you need to be concerned about is the chain tensile strength, which on the RX is among the upper range for most makers.
