Built from hardened carbon steel to resist wear, the ANSI #420 roller profile is a common fit for 100cc, 110cc and 125cc machines where a single-strand chain is required. The 10-foot length lets you cut to size for custom installations or maintain stock setups without multiple short links.\u003c\/p\u003e\n\n\u003ch3\u003eWill this chain fit my 100cc, 110cc or 125cc dirt bike?\u003c\/h3\u003e\n\u003cp\u003eCompatibility depends on sprocket pitch and width rather than engine displacement alone. The PGN 420 uses the ANSI #420 pitch and single-strand width commonly found on small dirt bikes, pit bikes, ATVs, mini bikes and go-karts. Check your sprocket pitch markings or measure chain pitch before installing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI #420 pitch — matches many 100–125cc small-frame drivetrains\u003c\/li\u003e\n  \u003cli\u003e240 links (10 feet) — long enough to size for front and rear sprockets\u003c\/li\u003e\n  \u003cli\u003eTwo connecting links included — simplifies joining and trial fitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow durable is the PGN 420 chain for off-road use?\u003c\/h3\u003e\n\u003cp\u003eThe chain is manufactured from carbon steel and heat-treated for improved fatigue resistance and working life. While not stainless, the carbon-steel construction offers a balance of strength and cost-effectiveness for everyday riding and utility chores.

Use appropriate pliers or a chain breaker to split links safely, and torque the connecting link clip to manufacturer guidelines. After installation, set correct chain slack and lubricate thoroughly before riding.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasure and remove excess links with a chain breaker\u003c\/li\u003e\n  \u003cli\u003eAttach one of the two supplied connecting links to join ends\u003c\/li\u003e\n  \u003cli\u003eAdjust tension and lubricate before first use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat applications beyond dirt bikes can this chain serve?\u003c\/h3\u003e\n\u003cp\u003eBecause it follows ANSI #420 dimensions and single-strand design, this chain adapts to many light industrial and hobby uses. It’s suitable for go-karts, mini bikes, scooters, garden equipment, and certain conveyor or small machinery tasks where a 420-sized roller chain is required. Its 10-foot length provides extra material for cutting to nonstandard setups.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eGo-karts and mini bikes — common small-vehicle drivetrains\u003c\/li\u003e\n  \u003cli\u003eLight machinery and conveyors — where 420 pitch is specified\u003c\/li\u003e\n  \u003cli\u003eSpare chain stock for workshops and maintenance kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? The PGN 420 10-foot chain suits riders, DIY mechanics and small-fleet owners who need a reliable, economical replacement for single-strand drivetrains on 100cc–125cc dirt bikes, ATVs, go-karts and similar equipment. It’s ideal when you want ample chain length to customize fit, two spare connecting links for easier joining, and a durable carbon-steel construction that responds well to regular maintenance.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this chain come ready to fit my bike?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The chain ships full length (240 links); you must cut to proper length and use a connecting link to join.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the PGN 420 rustproof?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — it’s carbon steel.
