NICHE Drive Sprocket Chain Combo for Yamaha YZF-R3 MT-03 YZF-R25 MT-25 Front 14 Rear 43 Tooth 520V-X X-Ring 112 Links
This NICHE combo is sized specifically for the R3, with a 14/43 tooth sprocket ratio that matches the stock configuration and a 520V-X X-ring chain at 112 links for a direct bolt-on fit — no cutting or resizing needed. The X-ring design retains lubrication better than standard O-rings, which suits the R3's commuter and sport-touring use well. Caveat: budget-conscious riders should know this won't outlast premium DID or RK chains under aggressive track use.
