Renold's chain
Here is the myth that "the market" works, exploded. Under threat from El Cheapo chains, Renold started to sell cheapo chain in parallel to their own stuff, to capture the market that thought that price was the only thing that counted. I was lucky enough to buy from someone who told me this, so I paid the extra, and got the good stuff. My Renold rear chain has never been adjusted, has done 12,000 Scott-oiled (that is probably significant) miles. Of course I don't for one moment believe that motorcycle dealers would pass off the el cheapo stuff as the real thing, while charging you the full price. Heavens, no.
But the answer is to buy Tsubaki or DID chain, specifically designed for motorcycles, and not Renold, which while good stuff , is actually industrial chain, good for a million hours if kept clean, oiled, and under a constant load. None of which is true of motorcycles. Not for the first time, we were conned into thinking that British made (Hans Renold was German) meant best. Just like British motorcycles were state-of-the-art. Until Honda exploded the con and sold a 750 four. A bit like Dorothy drawing the curtain on the Wizard of Oz, really.
Alton notchiness-Its a 'good en' alright it took every roller out of my center run of my primary chain when I fitted it ,mind you that was on the 1999 lap of the IOM and I was also still under the impression that Reynolds triplex was the good old stuff rather than steel spagetti for tin box camshafts it now is (welded rollers indeed!)
