    I am cleaning up a Seca 550 and the drive chain and sprockets seem to be in good condition (after degreasing and oiling). The chain seems to be very large compared to my other bikes and I am wondering if it is the correct size. The only stamp I can see is "RK 50So". Can anyone tell me what size this is? I can't find it on the RK website.

    So, are you saying that RK 50So equates to 530?

    what I am saying is the Maxim and Seca XJ550 take a 530HD chain 104 links long .
    with the newer chains it is stated in the thread I posted a link to you can go with a 520 chain 104 links long with the oring and x ring chains
