RENTHAL 1120-520 Grooved Twinring Rear Sprocket: The Ultimate Fusion of Durability and Lightweight PerformanceExperience the pinnacle of rear sprocket technology with the RENTHAL 1120-520 Grooved Twinring Rear Sprocket. Engineered for the most demanding off-road and supermoto riders, this revolutionary component from the Transmission category redefines expectations for longevity and performance. If you´re seeking a rear sprocket that refuses to compromise between the featherlight feel of aluminum and the incredible lifespan of steel, the Twinring is your definitive solution, offering the best of both worlds in one advanced package.The secret to its unmatched endurance lies in its groundbreaking dual-material design. The outer ring is constructed from an electro-less nickel coated steel, providing the ultimate defense against chain wear and the harsh elements. This robust construction ensures the RENTHAL Twinring will outlast a conventional all-aluminum sprocket by up to three times, translating to fewer replacements, lower long-term maintenance costs, and more time enjoying your ride. This exceptional durability makes it the ideal choice for riders who put serious hours on their machines.While the outer ring delivers brute strength, the inner core is where performance is perfected. Featuring Renthal´s renowned high-strength Ultralight™ 7075 T-6 aluminum—the same material used in their championship-winning sprockets—this design drastically reduces overall weight compared to an all-steel alternative. By minimizing unsprung mass at the rear wheel, the Twinring sprocket allows your motorcycle´s suspension to react more quickly to terrain changes and improves acceleration, giving you a distinct competitive advantage on the track or trail.Renthal´s engineering excellence is showcased in how these two materials are permanently joined. The steel outer ring is heated to 200°C, causing it to expand, and is then precisely fitted over the aluminum inner. As it cools, it creates an incredibly strong interference fit. This bond is further secured by a unique wave pattern, guaranteeing a permanent, inseparable connection for the life of the sprocket and eliminating any risk of failure under the most extreme riding conditions.Designed for real-world challenges, the RENTHAL 1120-520 sprocket incorporates features that keep you moving. Self-cleaning mud grooves are meticulously machined between each tooth. This intelligent design actively prevents the build-up of dirt, mud, and debris, which maintains optimal chain engagement, reduces premature wear on both the chain and sprocket, and further shaves off unnecessary weight. Additionally, the flat socket head screws provide extra structural strength against side impacts and are designed to avoid any interference with the chain guide, ensuring smooth and reliable operation lap after lap.Stop choosing between a long-lasting sprocket and a lightweight one. With the Renthal Twinring, you get both. It is the premier choice for riders who demand maximum performance and unparalleled durability from their transmission components.Product Specifications and Compatibility:Compatible models:KAWASAKI KLX 300 SM 2021.KAWASAKI KX 125 D 1985.KAWASAKI KX 125 F 1988.KAWASAKI KX 125 G 1989.KAWASAKI KX 500 C 1987.KAWASAKI KX 500 D 1988.Twinring™ Rear Sprocket.Inner ring is the same high strength Ultralight™ 7075 T-6 aluminum used for the standard Renthal sprocket.Outer ring is electro-less nickel coated steel for ultimate durability and is designed with the minimum amount of material to keep weight down.The outer ring is expanded at 200°C and then fitted over the inner, this interference fit combined with the wave pattern ensures a permanent bond for the life of the chainwheel.The flat socket head screws add additional strength to the chainwheel during side impacts and eliminates contact with the chain guide.Self cleaning mud grooves between each tooth prevent dirt build upand reduce chainwheel wear and weight.Will outlast a standard all aluminum sprocket by 3 times, yet is much lighter than an all steel rear sprocket. tradeinn Motardinn
