Renthal Twinring Rear Sprocket 49 Tooth Green for Kawasaki and Suzuki (1120-520-49GPGN)

Upgrade your motorcycle drivetrain with the Renthal Twinring Rear Sprocket, part number 1120-520-49GPGN. Designed for select Kawasaki and Suzuki applications, this 49-tooth sprocket combines the low weight of aluminum with the long-term durability of steel. Its green finish adds a distinctive appearance while maintaining the performance-focused construction expected from Renthal components.
The inner ring is manufactured from high-strength Ultralight 7075-T6 aluminum, the same premium alloy used in Renthal standard sprockets. The outer ring is made from electroless nickel-coated steel for excellent wear resistance and durability. It uses the minimum amount of material necessary to reduce weight, helping support responsive handling without sacrificing drivetrain strength.
During assembly, the outer ring is expanded to approximately 392°F and fitted over the inner ring. This interference fit, combined with the wave-pattern design, creates a permanent bond intended to remain secure throughout the chainwheel’s service life. Flat socket-head screws add strength during side impacts and help eliminate contact with the chain guide.
Self-cleaning mud grooves between each tooth help prevent dirt buildup, reducing chainwheel wear while contributing to lower overall weight. Renthal states that the Twinring design can outlast a standard all-aluminum sprocket by up to three times while remaining substantially lighter than an all-steel rear sprocket. This Renthal 1120-520-49GPGN sprocket is a durable choice for riders seeking reliable chain engagement, reduced maintenance, and lightweight drivetrain performance.
