Built for Chinese mini-bike and pit-bike platforms that commonly use 415\/428-series drive systems, the package is intended for riders who need a durable, easy-to-fit replacement for worn or mismatched chains. It’s especially useful when adapting non‑OEM parts, swapping gearing, or performing field repairs.\u003c\/p\u003e\n\n\u003ch3\u003eWill this chain fit my 49cc or 80cc motorized bicycle?\u003c\/h3\u003e\n\u003cp\u003eThe 415H-110L chain is sized for 415-series applications and the long 110-link length provides flexibility to fit many small-engine frames. It commonly fits 49cc, 60cc, 66cc and 80cc two-stroke motorized bicycles and many Chinese dirt bikes and pit bikes. Some Honda models that accept 428 chains may also be compatible, but you should check pitch and sprocket width before install.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eChain type: 415H, 110 links for adjustable fit\u003c\/li\u003e\n\u003cli\u003eCompatible engines: 49cc–80cc two-stroke setups\u003c\/li\u003e\n\u003cli\u003eCross-compatibility: works with many TaoTao, Buyang, Lifan, Kazuma, SUNL systems\u003c\/li\u003e\n\u003cli\u003eVerify: check sprocket pitch and width for precise match\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I shorten and install the chain using the included breaker?\u003c\/h3\u003e\n\u003cp\u003eThe kit’s chain breaker lets you remove excess links and press pins safely for a custom fit. After measuring chain wrap and determining the required length, use the breaker to drive pins out, install a connector link, then recheck tension and alignment.

The kit’s multiple connector links and the breaker tool make it practical for field repairs and gear changes. It’s supplied to fit a wide range of Chinese-made small motorcycles, ATVs, mowers and motorized bicycles used in racing, commuting or trail riding.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHeavy-duty 415H construction for improved wear resistance\u003c\/li\u003e\n\u003cli\u003e110 links for broad compatibility and custom cuts\u003c\/li\u003e\n\u003cli\u003eIncludes 10 connector links for repeat repairs\u003c\/li\u003e\n\u003cli\u003eTool included for onsite shortening and maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? This MRELC 415H-110L chain kit is aimed at DIY mechanics, pit crews and riders of small-engine bikes and pit bikes who need a robust, adjustable replacement chain. It’s a practical choice if you work with multiple Chinese-brand machines (TaoTao, Lifan, Buyang, SUNL, Kazuma, etc.), perform routine maintenance or need a reliable repair kit to keep a motorized bicycle or minibike running between shop visits. If you’re unsure about sprocket compatibility, measure your existing chain pitch and sprocket width or consult a mechanic before buying.\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 the 415H chain fit 428 sprockets?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: 415 and 428 are different pitches; some 428-compatible bikes accept 415 kits but verify sprocket pitch and width before installing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How many connector links are included?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The kit includes ten 415H connector links plus one chain breaker for installation and repairs.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MRELC","offers":[{"title":"Default Title","offer_id":48084398637214,"sku":"B0D7CG6SB9","price":33.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/mrelc-415h-110l-front-view.jpg?v=1785853784","url":"https:\/\/northtrailauto.ca\/products\/mrelc-415h-110l-heavy-duty-415h-chain-kit-for-49cc-80cc-motorized-bicycles-110-links-breaker-10-connector-links","provider":"North Trail Auto","version":"1.0","type":"link"}
