Almost sure it's a D.I.D. Came with my bike...01 M750...gold...made in Japan. That's all I know. I need to know so I can purchase a masterlink.
Thanks!
edit- a pic might help...woops. :D

Got a shot of the side plate? might be stamped there. Looking at it from the top, it's a 520 chain like so many others
the only stamp I can find is JAPAN.
I'm fairly certain it's a DID VX2520 CA-CYCLEWORKS but the only replacement master link I can find is for the ERV, the $200 chain. You think they're interchangeable?
dumb question, but did you check both sides of the chain. I would give CA-cycleworks a quick call to confirm fitment.
you need to know what it is, for example the did vm and vx have different size pins.
Why not pop the master and measure pin length, distance and diameter?
