A lot of folks over at R1-forum use the MVXZ 520 chain. Part of it is word-of-mouth advertising by the local sponsor, but yeah, its specs are in line with the DID 520ZVM-X chain. It actually has slightly better tensile strength too.
+1 on rivet style masterlinks. My 07 R1 had an EK chain with a clip style masterlink on it when I purchased it. It was gone after two rides - scary stuff.
