my cbr1000rr had an RK chain 530 o-ring. 18,000+ miles. changed it between 18-19,000 and didnt even have to change the sprockets and anly oiled 4 times, every time i oiled it, it would goo up my brakes! scary! so for safety i said no oil, ill replace the chain when worn.
i went through 2 chains on my SR500 then went to O-ring and never touched it again! im an o-ring chain believer and wouldnt get anything else! just my two cents.
