RENTHAL 441U-428 Ultralight Grooved Rear SprocketElevate your bike´s performance with the Renthal 441U-428 Ultralight Grooved Rear Sprocket, a pinnacle of engineering in the world of off-road and motocross transmission. Born from a legacy of championship-winning performance, this rear sprocket is meticulously designed for riders who demand the absolute best in terms of weight reduction, durability, and power transfer. It´s not just a replacement part, it´s a significant upgrade that you will feel on the track and trail.The core advantage of the Renthal Ultralight sprocket lies in its revolutionary weight savings. The ultralight design is 66% lighter than steel, yet incredibly durable, offering a dramatic reduction in unsprung weight on your motorcycle. This critical reduction allows your suspension to react faster and more effectively to terrain changes, improving traction and providing a much plusher ride. The decrease in rotational mass also leads to quicker acceleration, allowing you to get the holeshot and power out of corners with greater efficiency.Precision is paramount, which is why each sprocket is CNC-machined from a specially enhanced 7075-T6 aluminum alloy. This advanced material is specifically chosen for its unique combination of extreme strength and minimal weight, ensuring it can withstand the immense torque and harsh conditions of motocross and enduro racing without compromise. The computer-controlled machining process guarantees a perfect profile and concentricity for maximum power transfer and a flawless fit, eliminating drivetrain friction and vibration.For riders who face challenging conditions, the innovative design features are a game-changer. This sprocket includes machined self-cleaning mud grooves at each tooth to help prevent mud buildup and increase wear resistance. As you ride through mud, dirt, and sand, these strategically placed grooves actively channel debris away from the critical contact points between the chain and sprocket. This self-cleaning action not only prevents chain derailment but also significantly extends the life of your entire drivetrain, saving you money and ensuring reliable performance when it matters most.Finished with a hard-anodized coating, the Renthal Ultralight sprocket boasts superior resistance to corrosion and wear, maintaining its integrity and appearance even after countless hours of hard riding. Trusted by more factory race teams and world champions than any other sprocket brand, choosing Renthal means equipping your bike with the same cutting-edge technology used by the pros.Rear SprocketCompatible models:HUSQVARNA TC 85 17/14 2017-2022.HUSQVARNA TC 85 19/16 2017-2022.KTM SX 105 2007-2011.KTM SX 85 17/14 2003-2021.KTM SX 85 19/16 2003-2021. tradeinn Motardinn
