The \u003cstrong\u003eDirtyBike Large Sprocket and Chain Kit \u003c\/strong\u003ecombines our proven 520 X-Ring chain with durable steel sprockets to improve low-end torque, throttle response, and acceleration while maintaining balanced performance for trail, woods, and race conditions.\u003c\/p\u003e\n\u003cp data-start=\"517\" data-end=\"780\"\u003eIncreasing rear sprocket size gives the Ultra Bee more pull off the bottom, making it easier to climb, launch out of corners, and maintain control in technical terrain. It is a simple, effective upgrade for riders who want more usable power where it matters most.\u003c\/p\u003e\n\u003cp data-start=\"782\" data-end=\"1042\"\u003eLarger rear sprockets do slightly reduce top speed, and the larger the sprocket size, the greater the reduction. For most off-road riders, the tradeoff is worth it: better acceleration, stronger low-speed control, and improved performance in technical terrain.\u003c\/p\u003e\n\u003cp data-start=\"1044\" data-end=\"1289\"\u003eThe sprockets are manufactured from long-lasting, zinc-coated steel for excellent durability in aggressive riding conditions. Precision-cut, beveled teeth promote smooth chain engagement, helping reduce friction, drivetrain wear, and power loss.\u003c\/p\u003e\n\u003ch3 data-section-id=\"19zqy0x\" data-start=\"1291\" data-end=\"1303\"\u003eFeatures\u003c\/h3\u003e\n\u003cul data-start=\"1305\" data-end=\"1851\"\u003e\n\u003cli data-section-id=\"1dnav4f\" data-start=\"1305\" data-end=\"1341\"\u003eDesigned for the Sur-Ron Ultra Bee\u003c\/li\u003e\n\u003cli data-section-id=\"j4zogm\" data-start=\"1342\" data-end=\"1384\"\u003eImproves low-end torque and acceleration\u003c\/li\u003e\n\u003cli data-section-id=\"1l5l1jg\" data-start=\"1385\" data-end=\"1447\"\u003eHelps deliver stronger, more responsive off-road performance\u003c\/li\u003e\n\u003cli data-section-id=\"55lpfa\" data-start=\"1448\" data-end=\"1508\"\u003eSlightly reduces top speed depending on rear sprocket size\u003c\/li\u003e\n\u003cli data-section-id=\"1eti6pi\" data-start=\"1509\" data-end=\"1591\"\u003eLarger rear sprockets provide more acceleration with greater top speed reduction\u003c\/li\u003e\n\u003cli data-section-id=\"187gxxk\" data-start=\"1592\" data-end=\"1630\"\u003eIncludes heavy-duty 520 X-Ring chain\u003c\/li\u003e\n\u003cli data-section-id=\"1kkem0l\" data-start=\"1631\" data-end=\"1668\"\u003eDurable zinc-coated steel sprockets\u003c\/li\u003e\n\u003cli data-section-id=\"omzgu3\" data-start=\"1669\" data-end=\"1737\"\u003ePrecision-cut teeth with beveled edges for smooth chain engagement\u003c\/li\u003e\n\u003cli data-section-id=\"9nu7oe\" data-start=\"1738\" data-end=\"1789\"\u003eBuilt for trail, woods, hard enduro, and race use\u003c\/li\u003e\n\u003cli data-section-id=\"13ri5uq\" data-start=\"1790\" data-end=\"1851\"\u003eSimple drivetrain upgrade with noticeable performance gains\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePick up a \u003ca href=\"https:\/\/americansurron.com\/products\/laser-chain-alignment-tool?_pos=1\u0026amp;_psq=laser+chain+alignment+tool\u0026amp;_ss=e\u0026amp;_v=1.0\" title=\"Laser Chain Alignment Tool\"\u003eDirtyBike Laser Chain Alignment Tool\u003c\/a\u003e to ensure your chain is properly aligned for maximum performance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"DirtyBike","offers":[{"title":"13T\/50T","offer_id":54064891035958,"sku":"UB-C\u0026SK-50T-520-98L-XR","price":99.0,"currency_code":"USD","in_stock":true},{"title":"13T\/52T","offer_id":54064891068726,"sku":"UB-C\u0026SK-52T-520-100L-XR","price":100.0,"currency_code":"USD","in_stock":true},{"title":"13T\/54T","offer_id":54064891101494,"sku":"UB-C\u0026SK-54T-520-100L-XR","price":101.0,"currency_code":"USD","in_stock":true},{"title":"13T\/56T","offer_id":54064891134262,"sku":"UB-C\u0026SK-56T-520-102L-XR","price":102.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0281\/6212\/9968\/files\/Surron-UltraBee-DirtyBike-Chain-and-Sprocket-Set-520.jpg?v=1780326106","url":"https:\/\/americansurron.com\/products\/chain-and-sprocket-set-steel-surron-ultra-bee","provider":"eDirtyBike","version":"1.0","type":"link"}
