Combining a high-strength aluminum inner ring with a durable steel outer ring, this sprocket is engineered to withstand the rigors of off-road riding while minimizing weight.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eRenthal's Twinring™ rear sprocket significantly extends sprocket life compared to traditional aluminum sprockets, lasting up to three times longer. The inner ring is machined from Ultralight™ 7075 T-6 aluminum, the same material used in Renthal's renowned standard sprockets. The outer ring is constructed from electro-less nickel-coated steel, providing exceptional wear resistance. The outer ring is thermally fitted to the inner ring at 200°C, creating an incredibly strong and permanent bond via an interference fit and wave pattern design. Flat socket head screws further enhance the sprocket's strength, particularly against side impacts, while also preventing contact with the chain guide. Self-cleaning mud grooves are incorporated between each tooth to prevent dirt accumulation, reducing chainwheel wear and minimizing weight. This innovative design results in a sprocket that is lighter than an all-steel equivalent yet delivers exceptional durability. Optimize your motorcycle's performance with the Renthal Twinring™ rear sprocket – the perfect balance of strength and weight.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eInner ring crafted from high-strength Ultralight™ 7075 T-6 aluminum for reduced weight.\u003c\/li\u003e\n    \u003cli\u003eElectro-less nickel-coated steel outer ring maximizes durability and wear resistance.\u003c\/li\u003e\n    \u003cli\u003eThermally fitted outer ring ensures a permanent and robust bond.\u003c\/li\u003e\n    \u003cli\u003eFlat socket head screws provide additional strength and protect against side impacts.\u003c\/li\u003e\n    \u003cli\u003eSelf-cleaning mud grooves prevent dirt buildup, reducing wear and weight.\u003c\/li\u003e\n    \u003cli\u003eOutlasts standard aluminum sprockets by up to 3 times, providing exceptional value.\u003c\/li\u003e\n    \u003cli\u003eLighter than all-steel sprockets, improving overall motorcycle performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eBrand: Renthal\u003c\/li\u003e\n    \u003cli\u003eProduct Name: Sprocket\u003c\/li\u003e\n    \u003cli\u003eMounting Position: Rear\u003c\/li\u003e\n    \u003cli\u003eChain Size: 520\u003c\/li\u003e\n    \u003cli\u003eTooth Count: 49\u003c\/li\u003e\n    \u003cli\u003eMaterial: 7075-T6 Aluminum, Nickel-coated Steel\u003c\/li\u003e\n    \u003cli\u003eType: Drive\u003c\/li\u003e\n    \u003cli\u003eColor\/Finish: Red\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eEnsure the selected sprocket is compatible with your motorcycle's chain size and intended use.
