why are you going to a 520 chain? your profile says you have a 999.
If you are trying to save weight or make your bike faster, I am sure you can find less risky way of doing so. If that chain snaps, you will need a new motor case.
DID's website recommends 525.
999's have a wide torque band; lots of strain on that chain.
