Renthal 440-420 Grooved Front Sprocket | KTM SX 65 & Husqvarna TC 65Elevate the performance and durability of your youth motocross bike with the Renthal 440-420 Grooved Front Sprocket. Engineered for the serious racer and demanding rider, this premium component from the Transmission category is meticulously designed to deliver maximum power transfer, exceptional longevity, and unwavering reliability. It stands as the ultimate upgrade for your KTM or Husqvarna machine, ensuring your drivetrain can handle the toughest track conditions.At the heart of this sprocket lies a core of immense strength and resilience. It is precision CNC-machined from a specially developed 655M13 nickel chromium steel, a material renowned for its incredible toughness. To achieve the perfect balance of properties, the sprocket undergoes a rigorous case hardening and core refining process. This creates an ultra-hard, wear-resistant outer surface to combat chain friction, while the core remains less brittle to absorb the intense shock loads of motocross. The result is a front sprocket that can withstand the brutal forces of race starts, harsh landings, and high-RPM abuse, ensuring a significantly longer service life and giving you confidence in your equipment.Renthal´s innovative design truly shines when conditions deteriorate. This front sprocket features specially machined self-cleaning mud grooves at the base of each tooth. As the chain engages and disengages, these grooves actively channel mud, grit, and sand away from the critical contact areas. This crucial feature prevents the mud packing that is a common cause of accelerated chain and sprocket wear. By maintaining a clean and efficient interface, the sprocket ensures consistent power delivery and dramatically extends the life of your entire drivetrain, giving you a distinct competitive advantage when the track turns sloppy.Every gram counts in racing, and Renthal´s Ultralight design philosophy is evident in the 440-420 model. Through meticulous engineering analysis and advanced CNC machining techniques, this sprocket achieves a remarkable 10-15% weight reduction compared to standard front sprockets. This reduction in rotational mass allows your engine to spin up faster, translating to crisper throttle response, improved acceleration out of corners, and a more efficient transfer of power directly to the rear wheel. It´s a tangible performance gain that can be felt on every single lap.Choose the championship-proven technology of Renthal and equip your bike with a front sprocket that offers the ultimate combination of strength, lightness, and long-lasting performance.Compatible models:HUSQVARNA TC 65 2017-2022.KTM SX 65 2009-2021.Key Features:* Product Type: Front Sprocket.* Self-Cleaning Design: Features machined self-cleaning mud grooves at each tooth to prevent buildup and help increase wear resistance in all conditions.* Ultralight Construction: Engineered for a 10-15% weight savings, reducing rotational mass for enhanced acceleration and engine response. tradeinn Motardinn
