I had 9000 miles on my Tsubaki before it needed adjustment. Good Oring chains (Tsubaki, DID and a couple of others) on other bikes have lasted me over 30,000 miles. They are considerably better than the stock chain which, in some cases, don't make it to 10,000 miles. RE isn't the only one uses crap chains as OEM. I get three to four times the mileage out of good chains over the OEMs. Spending a little more money can save you a lot of money and time. They don't tear up sprockets like the OEM, and require less maintenance labor time. They're a win-win deal.
