• Number of teeth: 12
• Chain pitch: 520
• Type: 453, standard version
• Designed to minimize friction and optimize torque/rear wheel transmission

This Renthal sprocket is a preferred choice for motocross riders seeking a balance between lightweight design and durability. Its robust construction withstands the demands of the terrain while remaining lighter than many stock components, helping to reduce unsprung mass and improve the bike's responsiveness. The precise machining ensures a clean engagement with 520 chains, resulting in healthy engine response and controlled wear.

Compatible with many motocross models — including KAWASAKI KX 250 (2022, 2026, and variants) — it easily integrates into a performance-oriented setup. Recommended for competition or for demanding riders looking to enhance the reliability of their drivetrain.
