Made from quality alloy, the sprocket is machined for consistent tooth profile and straightforward maintenance, while the matched #35 chain and flywheel adapter make installation faster and reduce the chance of mismatched components.\u003c\/p\u003e\n\n\u003ch3\u003eWill this sprocket and chain fit my electric go-kart or mini bike?\u003c\/h3\u003e\n\u003cp\u003eThe Doinal #35 kit is designed to match vehicles that use a #35 chain standard and a 65-tooth rear sprocket. Confirm your vehicle’s chain pitch and mounting dimensions before ordering to ensure compatibility. If your motor or swingarm uses the listed measurements, this kit will replace worn parts directly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eChain size: #35 standard\u003c\/li\u003e\n  \u003cli\u003eSprocket teeth: 65T, overall diameter 200 mm (7.8 in)\u003c\/li\u003e\n  \u003cli\u003eMounting hole diameter: 7 mm (0.27 in)\u003c\/li\u003e\n  \u003cli\u003eCenter hole (hub) diameter: 54 mm (2 in)\u003c\/li\u003e\n  \u003cli\u003eChain length supplied: 108 links (uncut for custom fit)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is installation and maintenance?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward for anyone with basic tools and experience working on small drivetrains. The kit arrives with the sprocket, full-length chain, and a flywheel adapter to align the sprocket with common motor hubs, reducing the need for extra parts.

Because the package includes a new chain and adapter, you also get improved reliability if your original parts were worn. This is a practical upgrade for heavier riders or off-road use where low-end traction matters more than peak speed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e65 teeth increases wheel torque relative to smaller rear sprockets\u003c\/li\u003e\n  \u003cli\u003eNew chain reduces stretch-related slippage\u003c\/li\u003e\n  \u003cli\u003eFlywheel adapter improves alignment and drivetrain life\u003c\/li\u003e\n  \u003cli\u003eBest for load-bearing and off-road traction improvements\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? The Doinal #35 65T sprocket kit is aimed at hobbyists, DIY mechanics, and small-vehicle owners who need a reliable replacement or want a modest gearing change for electric go-karts, Razor-style dirt bikes, RX\/MX series minibikes, and small ATVs. Choose this kit if your vehicle uses a #35 chain pitch and you want a complete, ready-to-fit package that reduces sourcing multiple separate parts. If you’re unsure about fitment, measure your current sprocket’s mounting hole pattern and chain pitch, or contact us with your vehicle model and motor spec for guidance.\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: Is the 108-link chain already the final length?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — the 108-link chain is full length so you can remove links to match your vehicle’s required length.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this sprocket fit Razor MX650 or RX600 models?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits many Razor models listed if they use a #35 chain and matching hub dimensions; verify mounting hole and hub sizes first.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"doinal","offers":[{"title":"Default Title","offer_id":48083077824670,"sku":"B0DB21GNBD","price":57.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/doinal-35-sprocket-front-view.jpg?v=1785823803","url":"https:\/\/northtrailauto.ca\/products\/doinal-35-rear-sprocket-kit-65t-alloy-sprocket-108-link-chain-flywheel-adapter-for-go-karts","provider":"North Trail Auto","version":"1.0","type":"link"}
