Renthal Twinring™ Rear Sprocket - 49 Tooth - Red for Honda 1540-520-49GPRD

The Renthal Twinring™ Rear Sprocket offers a high-performance upgrade for Honda motorcycles, featuring a durable and lightweight design. Crafted with an inner ring made from Ultralight™ 7075 T-6 aluminum, the same high-strength material used in Renthal's standard sprockets, this sprocket provides exceptional strength while maintaining a reduced weight profile. The outer ring is constructed from electro-less nickel coated steel, offering superior durability and resistance to wear, ensuring long-term reliability even in demanding riding conditions. The manufacturing process involves expanding the outer steel ring at 200°C and fitting it over the aluminum inner ring with an interference fit, reinforced by a wave pattern that guarantees a permanent bond for the lifespan of the chainwheel. This innovative construction ensures the sprocket withstands side impacts and harsh impacts during intense riding sessions. The flat socket head screws enhance the sprocket's strength during side impacts and prevent contact with the chain guide, adding to its durability. Additionally, self-cleaning mud grooves between each tooth help prevent dirt buildup, reducing chainwheel wear and keeping maintenance to a minimum. The design of this sprocket allows it to last up to three times longer than standard all-aluminum sprockets, making it a cost-effective choice for serious riders. Despite its increased durability, the Twinring™ sprocket remains significantly lighter than all-steel options, providing a perfect balance of strength and weight reduction. Suitable for Honda models with a 520 chain size, this 49-tooth sprocket is an excellent upgrade for improving power transfer and longevity in off-road or motocross applications.
