Renthal Front Sprocket 447 / 520

Renthal front sprockets are carefully crafted in our state-of-the- art manufacturing facility in Manchester, UK using only the highest- grade raw materials available.

Using advanced computer engineering alongside CNC machining, Renthal consistently achieves perfect concentricity, fitment, load dispersion and uncompromising strength whilst ensuring maximum power delivery from each and every motocross front sprocket we produce.

As a safety critial external drive component, Renthal prides itself on creating the number one choice of motocross front sprockets as used by the world's premier athletes and race teams.

Features:

• CNC Machined: To account for the extremely high tolerances required for engine components, Renthal utilises in-house CNC facilities to accurately machine each individual sprocket to the tightest tolerance possible.
• Core Refined: Core-refined 655M13 Nickel-Chrome- Molybdenum alloy steel provides the ultimate combination of strength and hardness.
• Mud Grooves: Self-cleaning mud grooves between every tooth on both sides to help prevent dirt build-up.
• Case Hardened: The case hardening process ensures that the sprocket has the longest service life possible. Each sprocket undergoes heat treatment to harden the surface.
