I ran 520s on both my Ducati and Speed Triple. No problems at all. The key is, correct adjustment. Same thing with aluminum rear sprockets. Steel fronts are the way to go. Aluminum rears wear out a bit faster, but not much if you do proper maintenance. If you get a high quality chain it is not a problem to run a 520. If you change your sprocket sizes your mileage recording will be incorrect as well as your speedometer. You will need to get a speedo-healer to compensate if that is an issue for you.
In terms of changing chains/sprockets etc. I have always stuck with changing the entire package at the same time. It's less hassle and you know exactly what the mileage is on the entire final drive.
