Going cheap on chains means going with the Honda parts. Honda chose a mid quality version of chain for the NC from various suppliers. Those same suppliers to Honda along with other suppliers sell better grade chains than what Honda chose. You can buy a better aftermarket chain for probably less than the OEM part. DID VX2 chains have been popular amongst owners on this forum. Whether they’re gold or black makes no difference.
The OEM Honda sprockets are fine and probably reasonably priced.
In other aftermarket news, JT sprockets are OK but JT chains are reportedly very short lived.
