Having checked my R1 manuals, there's no reference to wear. Yamaha tell me that the chain wears not at all in use, except if it's starved
of oil.. I guess the wear is then obvious!
The GSXR bibles again have no limits specified (it's the same chain), just refers to 'any discernable play in the links' as a reason
to fail it. I can lay any of my used GSXR chains as you've photgraphed and get the same curvature. I have no new ones to hand right now.
Thanks for making me look. I normally just dispose of them regardless of age or usage. I guess I'm just paranoid, but I rarely re-use anything.
By the time I've bored and plated the thing, new pistons, Carillo rods, stroker crank, one piece valves, race cams, etc.... not much gets left!
