The Rolon HPORC 391 is a purpose-built brass kit for the Dominar 250 specifically, with its own tooth count and chain length engineered around this bike, not borrowed from the 400.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"15:1-15:467;649-1115\"\u003eBrass-plated inner and outer chain link plates deliver genuine corrosion resistance along with a premium gold-toned finish that suits the Dominar's aggressive styling. The sprockets are heat-treated carbon steel with induction-hardened teeth, precision-machined to reduce noise and vibration for a quieter, smoother ride, and pass 18 production stages and 15 individual quality checks before shipping — engineered for real durability, not just a shinier replacement.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"17:1-17:271;1117-1387\"\u003e\u003cstrong\u003eImportant fitment note:\u003c\/strong\u003e the Dominar 250 uses a different tooth count from the Dominar 400 (14T\/46T vs 15T\/45T) — these kits are NOT interchangeable despite sharing the Dominar name. Always confirm which engine size your customer's bike has before selling either kit.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"19:1-19:71;1389-1459\"\u003e\u003cstrong\u003eIn the box:\u003c\/strong\u003e front sprocket, rear sprocket, and brass-plated chain.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"21:1-21:353;1461-1813\"\u003e\u003cstrong\u003eKeeping it running well:\u003c\/strong\u003e lubricate every 500km for seal-ring chains (1000km for standard), clean every 2500–3000km with a nylon brush — never a steel wire brush or high-pressure jet directly on a seal-ring chain — and maintain at least 1 inch of chain slack. Replace chain dampers at the same time as the kit.
