A worn one stretches, kinks and loses its lubrication, and you feel it as a snatchy, uneven drive on and off the throttle long before it lets go. Sealed-ring chains (O-ring, X-ring and similar) keep grease sealed inside every link, which is why they last far longer on the street than non-sealed chains.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMRU chains utilize RK's proprietary Ultra Thin Seal U-Rings which allows the thickness of the seal to be less than 50% of the most common O-ring seal\u003c\/li\u003e\n  \u003cli\u003eMRU features 4 times longer chain life and will require less chain adjustments than comparable non-sealed 420 chains\u003c\/li\u003e\n  \u003cli\u003eLightweight, low friction, sealed, U-Ring 420 pitch chain perfect for Honda® Monkey and Honda® Grom\u003c\/li\u003e\n  \u003cli\u003eChosen by pitch and link count, not by bike model\u003c\/li\u003e\n  \u003cli\u003eCount the links on your current chain, or check your owner's manual for the stock length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eChange the chain and both sprockets together. A new chain on worn sprockets wears out quickly, and so do new sprockets on an old chain.
