One important note to state. IMO, no matter what chain you go with, you must keep the sucker "properly" lubed or it WILL fail. My Ultra Turbo Busa I sold Tommy Grimes was fitted with a Rivet Link D.I.D. that was very stout. I kept it lubed. Tommy did not. One day, about a year after he bought the bike, he sent me an E-mail with pics of it sitting by the side of the road with a busted chain, a snapped off mainshaft and the cases were busted with a pile of oil leaking out. He did not lube the chain.
