This CNC-machined aluminum sprocket is designed to provide precise manufacturing quality and consistent fitment while helping reduce unsprung weight compared with conventional steel sprockets.\u003cbr\u003eThe rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum, providing a lightweight construction that is approximately 33% lighter than steel without sacrificing the strength needed for demanding riding conditions. Its reduced weight can help improve drivetrain response and contribute to more efficient power transfer from the engine to the rear wheel.\u003cbr\u003eRenthal also equips this 56-tooth sprocket with a specialized tooth profile that helps the chain roll smoothly on and off the sprocket. This design supports longer sprocket and chain wear, reduced drivetrain noise, and efficient operation throughout the service life of the component. The red finish adds a distinctive appearance while complementing performance-focused motorcycle builds.\u003cbr\u003eDesigned for compatible Honda applications, the Renthal 189U-420-56GRRD combines precision CNC machining, lightweight 7075-T6 aluminum, and a chain-friendly tooth profile in a durable replacement or performance upgrade.
