Stark Varg MX RK MXU UW-ring Gold 520 Chain - 114T

The RK MXU is the 520-pitch drive chain used on the Stark Varg MX, supplied at 114 links with RK's UW-ring sealing. It runs from the front sprocket to the rear sprocket, which on a standard MX means the 14/47 combination Stark ships the bike with. A different sprocket pairing may call for the chain to be shortened to suit.
