NICHE Drive Sprocket Chain Combo for Kawasaki Ninja 300 EX300 Z300 Front 14 Rear 42 Tooth 520V-X X-Ring 106 Links
The NICHE combo is a direct fit for the Z300, matching the factory 14/42 tooth sprocket setup and the correct 520 chain pitch, so there's no guesswork on sizing. The 520V-X X-ring design reduces friction and holds lubrication better than standard O-rings, which suits the Z300's commuter-friendly riding style and helps extend service intervals. Caveat: installation still requires a chain breaker and rivet tool, so budget for those if you don't already own them.
