Looks cool. Haven't ridin it yet. Oring chains are usually pretty good. Planning to put it on my xs650.
As part of their continuing quality improvement program, the RK Chain Factory has made a running production upgrade to their best selling 530XSO chain. The new upgrade GBXSO and non-gold XSO chains features RK's proprietary "RX-Ring" seal design and is offered in 520, 525 and 530 versions. Viewed in cross-section, the RK "RX-Ring" has two lubrication pools and seal points versus the single seal point / pool design of a regular O-ring chain. RK's new GBXSO chains offer quality, performance and unbeatable value, for all but the most demanding high performance applications.
