I purchased a 520 conversion kit off of ebay from Sum of All Parts. It was supposed to come with a RK GXW chain but I received a WPS 520HSO chain, part #69-5820G. When I contacted them about it they argued that I did not read the description close enough (even though the GXW was in MUCH larger print than the WPS) but also said that: "The tensile strength on the TYC is actually 8987 vs 8800 on the RK GXW Chain. Both of which are more than capable of handling the horsepower output of your CBR." They offered to send me the GXW chain if I paid them $20 more.

My questions are: 1. Does anyone have experience with the WPS chains? 2. Am I correct in thinking that the tensile strength is not as stated? 3. Should I argue some more or pay the $20 for what would likely be a better chain?

My ultimate goal is to see how quickly I can reach top speed, and I want the chain to be up to the task. I don't want any weak links

 

ebay is hit and miss.... somtimes you get good sellers sometimes you dont.... i recommend returning the 520 conversion and keeping the 530.... not that much lighter... but thats my .02........ check out a similar post that tkr wrote about 520 conversion
