Renthal 112U-520 Ultralight Grooved rear sprocket

Discover the pinnacle of transmission performance with the RENTHAL 112U-520 Ultralight Grooved Rear Sprocket. Engineered for riders who demand the absolute best, this sprocket is more than just a replacement part; it is a fundamental upgrade to your motorcycle´s drivetrain, designed to deliver a tangible advantage in performance, durability, and weight savings. Trusted by more World Champions than all other sprocket brands combined, Renthal´s legacy of racing excellence is built into every component they produce.

Elevate your ride by significantly reducing unsprung weight. The Ultralight design is a game-changer, shedding critical pounds from your motorcycle´s final drive. This drastic reduction in rotational mass leads to sharper acceleration, more responsive handling, and improved suspension performance, allowing your rear wheel to track the terrain with greater precision. Whether you are navigating technical off-road trails, hitting the motocross track, or carving corners on your supermoto, you will feel the immediate difference in agility and control.

Durability is not compromised for weight. This rear sprocket is meticulously crafted using advanced manufacturing techniques to ensure it can withstand the most punishing conditions. The result is a component that offers an exceptional service life, providing reliable power transfer and consistent performance ride after ride. Its inherent strength ensures that you can push your machine to its limits with complete confidence.

A standout feature is the innovative self-cleaning design. Expertly machined mud grooves are integrated at the base of each tooth. These channels are specifically engineered to clear away mud, dirt, and grit from the critical contact points between the chain and sprocket. This active-clearing mechanism drastically reduces wear on both components, extending the life of your entire drivetrain and ensuring smooth, efficient operation even in the muddiest and most abrasive environments. Say goodbye to performance-robbing buildup and hello to consistent power delivery in all conditions.
