Regina Chain question?
 

135 ORNV4W-104 Racing is on the label.

is it a 525 or 520? as I need a split link for it?

Recommendations, thoughts?

Like I guess you've done Chris, I checked the Regina website but can't find a 135 ORNv4.......

Can only suggest you email them at moto@regina.it and fire the question to them in the hope they get back to you quickly.

Gc

A 135 ORN is a 520.

No idea what your full part number means though.

Thanks - I will contact them to ask.

I had done the net search, but challenged on the part number details too.
