Manufacturer Reference: 801 13 18NC

PBR presents a steel drive sprocket designed for demanding motocross riders. Drawing on experience gained in competition, this standard 801 sprocket with a 428 pitch features a robust design and precise tooth profile for a reliable replacement of the original front sprocket.

• Material: high-quality 18NCD5 steel alloy
• Number of teeth: 13 teeth (sprocket)
• Chain pitch: 428
• Version: Standard, direct replacement mount

The 18NCD5 alloy ensures excellent resistance to corrosion and abrasion, while the tooth finish minimizes friction with the chain for more uniform wear. The manufacturing process controlled by PBR guarantees dimensional accuracy suitable for off-road conditions, ensuring a smooth and consistent transfer of engine power to the rear wheel.

Designed for the motocross environment, this sprocket is particularly suitable for the listed TM Racing models (MX 144 2018, EN 144 2012, MX 125 2011) and any motorcycle requiring a 801 sprocket with a 428 pitch. Easy installation as a standard replacement — be sure to check the condition of the chain and lubrication during installation.
