NICHE Gold 520 X-Ring Chain 118 Links with Connecting Master Link
The NICHE Gold 520 X-Ring Chain matches the KTM 390 Duke's factory 520 chain pitch exactly, making it a direct replacement without any sprocket swaps. At 118 links you'll have enough to cut to the Duke's required length with links to spare. The X-ring design reduces friction and holds lube longer than standard O-rings, which suits the Duke's rev-happy single well. Caveat: gold finish shows road grime quickly, so expect more frequent cleaning if aesthetics matter to you.
