Made from heat-treated carbon steel with hardened links and rollers, the LKSM 420 chain is sized for 420-type drivetrains and supplied with a universal chain breaker and six connector links so you can cut, fit and join the chain to the exact length your vehicle requires. Check your vehicle’s chain pitch and required link count before fitting.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this chain improve drivetrain reliability?\u003c\/h3\u003e\n\u003cp\u003eThe LKSM 420 chain uses heat-treated rollers and hardened side plates to resist stretching and abrasive wear under repeated load cycles. Consistent manufacturing tolerances ensure smoother engagement with sprockets, which reduces vibration and premature wear on both chain and gears.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHeat-treated carbon steel construction for increased fatigue life\u003c\/li\u003e\n  \u003cli\u003eHardened rollers and links to slow wear and elongation\u003c\/li\u003e\n  \u003cli\u003ePrecision-cut 420 pitch links for accurate sprocket mesh\u003c\/li\u003e\n  \u003cli\u003eIncludes connector links to form a secure master link\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my 50–125cc bike, ATV or go-kart?\u003c\/h3\u003e\n\u003cp\u003eThe chain is a 420 standard roller chain with 132 links before trimming, which suits many 50cc–125cc machines such as older CRF50\/70\/80 and XR50\/70\/80 models and comparable minibikes or quads.
