520 is really more for race performance. On the street it's not really that noticalble from what I hear. I do know that it is a thinner chain which would probably mean it's going to be less durable. Definitely not a good thing if you're hammering it with abrupt throttle changes like with wheelies and other stunting activities.

 

I do want to thank everyone for all the awesome info. I would appreciate it if u would all SCREW OFF now.















J/K and keep that **** comin

 

the reason a 520 would break stunting but not racing is
stunting = clutching it up and sudden jerks on the chain
racing = constant pressure not sudder jerks

 

Can a stock sized 525 chain be kept if I'm going -1,+2? Or do I need to add links or buy a brand new chain?

 

It will work U wont have to add any links
