My last few builds I have started using the DID X Ring Chains rated at 8120# average tensile strength.
What are you folks using??
i use the renthal r3-2 o ring chain
Well worth the $$$
RK 520XOSO 8500# tensile strength
110-120 length is around $80 on ebay
and their pre-stretched so not much adjusting
RK X ring 520EXW gold side plates
Primary Drive stock length x ring. 8200lbs no problems so far.
I'm running the RK X-Ring Chain. Installed 3/2011, adjusted a few times and it pretty much is good to go now with my 70+HP sand abusing quad. I tried a non-o-ring chain and it lasted ONE trip to Glamis and was worn out. ONE TRIP!
Im also using the x-ring Primary drive chain. got about 6 dune seasons on it. Very nice 50 dollar chain.
i just got a rk GB520MXU 9000# tensile and its lighter than my ktm volar chain i was running. this season will show if its as good as rk says it is. they claim its their top recommended chain they sell for mx type racing.
