My stock DID chain has been the only thing to really fail on my '17 300RR Race so far at 30 hours. 2 o-rings were bulged at 10 hours, kept an eye on them, and now they're gone. Links are metal to metal in 2 spots now. Beta will not replace under warranty, even though obviously a manufacturing defect (by DID). Never had a chain fail like that before. Anyway, I don't want to replace the nearly new slider, just the chain. Think I'll drop the $$$ for the DID VT2 and give them one more try.
Would normally just buy the Rocky Mountain ATV house brand Primary Drive gold x-ring chain (has been great on many other bikes), but it is slightly WIDER (~2mm) than most chains so not a good fit on Betas with that tight clearance at the bolt/kickstand spring mount.
What chain oil are you using? Any other chemicals that are attacking the o-rings?
