Standard aluminum sprockets suffer from a \"durability gap,\" where rapid flexing and thin material structures cause the teeth to hook quickly, ruining your chain and robbing you of rear-wheel power. The Moose Offroad 1211-1539 Rear Aluminum Sprocket solves this power-loss pain point for off-road riders by using premium, extra-tempered 7075 T651 aluminum that resists warping and delivers absolute structural integrity through the roughest terrain.\u003c\/p\u003e\n\u003cp\u003eThis isn't just an ordinary replacement gear; it is a weight-saving performance upgrade engineered for perfect System Synergy with your bike's final drive assembly. CNC-machined to perfection, this 49-tooth sprocket features a clean raw silver finish that maintains a classic look while protecting against severe friction. By maintaining optimal tooth thickness and uniform roundness, it guarantees a Matched Performance interface with your drive chain, delivering smoother power transfer, minimal friction, and a Factory Quality standard you can trust lap after lap.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003e1211-1539 (49 Tooth Aluminum Sprocket):\u003c\/b\u003e A 100% CNC-machined 520 chain size rear drive sprocket finished in raw silver aluminum, engineered to provide custom gearing adjustments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eExtra-Tempered 7075 T651 Aluminum:\u003c\/b\u003e Receives a specialized thermal tempering step that minimizes distortion under heavy load and maximizes structural rigidity compared to thin standard 7075 T6 blends.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e100% Fully CNC Machined:\u003c\/b\u003e Carved entirely from a solid billet block with zero metal stamping or grinding, preserving original grain alignment and structural strength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOptimal Tooth Thickness Profile:\u003c\/b\u003e Every tooth face is precision contour-cut to establish absolute full-width chain roller contact, lowering localized friction and extending drive component lifespan.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDebris Clearing Edges:\u003c\/b\u003e Cleanly cut gullet valleys help evacuate mud, sand, and trail debris instantly, preventing sudden chain tension spikes during sloppy trail conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUSA Engineered Precision:\u003c\/b\u003e Built to exacting geometric tolerances to ensure absolute concentricity, eliminating tight spots as the rear wheel spins.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eMoto-House MX Pro Tip:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eWhen upgrading to an advanced aluminum sprocket, always inspect the overall status of your drive line. For perfect Matched Performance and to protect your new premium alloy component from rapid wear, never run a new sprocket with an old, stretched chain. Install a high-tensile 520 sealed O-ring or X-ring chain along with a fresh countershaft sprocket. Always torque the rear sprocket bolts in a cross pattern to factory manual specifications, and ensure proper chain slack is maintained to secure smooth operation.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; text-align: left;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\u003cth style=\"padding: 10px; border: 1px solid #ddd;\"\u003eYear\u003c\/th\u003e\n\u003cth style=\"padding: 10px; border: 1px solid #ddd;\"\u003eMake\u003c\/th\u003e\n\u003cth style=\"padding: 10px; border: 1px solid #ddd;\"\u003eModel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2005 - 2013\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e250 RR \/ 350 RR \/ 400 RR \/ 450 RR \/ 498 RR \/ 500 RR \/ 520 RR \/ 525 RR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2000 - 2015\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eGas Gas\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eEC 125 \/ EC 200 \/ EC 250 \/ EC 300 \/ EC 300F (Including Racing \u0026amp; R Models)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e1997 - 2014\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eGas Gas\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eMC 250 \/ MC 300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2006 - 2011\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eSherco\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e450 SE \/ 510 SE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e1990 - 1995\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eSuzuki\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eDR250S \/ DR350S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFAQ Questions\u003c\/h3\u003e\n\u003cp\u003eQ) \u003cb\u003eWill this aluminum sprocket wear down faster than a standard steel sprocket?\u003c\/b\u003e\u003cbr\u003eA) Aluminum sprockets are inherently lighter than steel to decrease unsprung rotational mass for faster acceleration. To balance this out, Moose Offroad treats this sprocket with an extra-tempering process (T651) that vastly increases material density and resistance over standard aluminum options.\u003c\/p\u003e\n\u003cp\u003eQ) \u003cb\u003eWhat chain size does this 49-tooth rear sprocket require?\u003c\/b\u003e\u003cbr\u003eA) This rear sprocket is engineered to integrate perfectly with standard high-performance 520 width drive chains, which is the factory standard for off-road dirt bike machinery.\u003c\/p\u003e\n\u003cp\u003eQ) \u003cb\u003eDoes this product include replacement sprocket bolts and locking nuts?\u003c\/b\u003e\u003cbr\u003eA) No, this includes the individual 49-tooth rear aluminum sprocket only.
