Violent torque forces and gritty off-road mud quickly round off standard alloy sprockets, stretching your chain prematurely and dragging down your rear-wheel power delivery. The Moose Offroad Steel Rear Sprocket eliminates this critical parasitic power loss, restoring immediate power transfer and giving you the instant rear-wheel bite needed to clear triple jumps and technical rock sections.\u003c\/p\u003e\n\u003cp\u003eEngineered with Factory Quality materials, this high-performance drive sprocket is precision-cut from premium-quality C45 high-carbon steel to easily outlast standard aluminum components. Advanced CNC machining keeps manufacturing tolerances exceptionally tight for optimal chain alignment, while custom-engineered lightening holes significantly lower rotational mass without compromising the sheer structural strength required to handle high-horsepower enduro engines.\u003c\/p\u003e\n\u003ch3\u003eKey Performance Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eRestores Hard-Hitting Drive Power:\u003c\/b\u003e Provides pristine mechanical tooth profiles to eliminate chain slop and optimize acceleration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFactory Quality C45 High-Carbon Steel:\u003c\/b\u003e Delivers maximum structural durability, resisting tooth hooking and premature wear far better than aluminum.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCNC Precision-Machined Tolerances:\u003c\/b\u003e Guarantees flawless fitment and precise concentricity to keep your 520 chain tracking straight.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eEngineered Lightening Holes:\u003c\/b\u003e Strategically removes unsprung weight to maintain rapid throttle response and quick rear-wheel spin-up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAttractive Zinc-Plated Finish:\u003c\/b\u003e Provides a bright, corrosion-resistant outer shield that protects against mud, track wash, and rust.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eMoto-House MX Pro Tip:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eNever mount a brand-new rear sprocket onto a worn, stretched drive chain. An old chain has a different pitch tolerance and will rapidly grind down your fresh sprocket teeth within just a few hours of riding. For maximum drivetrain lifespan, always replace your front sprocket, rear sprocket, and 520 chain as a complete matching set.\u003c\/p\u003e\n\u003ch3\u003eFitment Application Data\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto;\"\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #ddd;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f2f2f2; text-align: left;\"\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #ddd;\"\u003eYear\u003c\/th\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #ddd;\"\u003eMake\u003c\/th\u003e\n\u003cth style=\"padding: 8px; 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: 8px; border: 1px solid #ddd;\"\u003e2013 - 2025\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e250 RR \/ 300 RR \/ 350 RR \/ 430 RR \/ 480 RR (Full Fitment Spectrum)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e2013 - 2024\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e390 RR \/ 400 RR \/ 450 RR \/ 498 RR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e2014 - 2025\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e350 RR 4T \/ 390 RR 4T \/ 430 RR 4T \/ 480 RR 4T \/ 390 RS \/ 430 RS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch3\u003eFAQ Questions\u003c\/h3\u003e\n\u003cp\u003eQ) \u003cb\u003eIs this carbon steel rear sprocket heavier than an OEM Style aluminum sprocket?\u003c\/b\u003e\u003cbr\u003eA) This steel sprocket is engineered with Factory Quality high-carbon steel for maximum lifespan, using specialized lightening holes to offset weight while maintaining superior strength compared to aluminum.\u003c\/p\u003e\n\u003cp\u003eQ) \u003cb\u003eWhat chain size does this Moose Offroad sprocket require for installation?\u003c\/b\u003e\u003cbr\u003eA) This 51-tooth rear drive sprocket is precision-machined specifically for a standard 520 size motorcycle drive chain.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003ca href=\"\/search?q=Beta+520+Chain\"\u003eBeta 520 Drive Chains\u003c\/a\u003e | \u003ca href=\"\/search?q=Beta+Front+Sprocket\"\u003eBeta Front Drive Sprockets\u003c\/a\u003e | \u003ca href=\"\/search?q=Moose+Offroad\"\u003eMoose Offroad Collection\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003eMoto-House MX – Choice of Champions\u003c\/b\u003e – is located in Clermont\/Montverde, FL.
