PBR Standard Steel Sprocket 266 - 520 (Manufacturer part number: 266 13 18NC)
Drawing on PBR's expertise from competition, this front sprocket made of steel is designed for demanding riders seeking a robust and reliable replacement part. Its design follows strict manufacturing processes to ensure a consistent tooth profile and longevity under both road and off-road conditions.
- Material: 18NCD5 steel alloy, high quality
- Number of teeth: 13 teeth (sprocket)
- Chain pitch: 520
- Type / version: 266 - standard version
The composition of 18NCD5 offers good resistance to corrosion and abrasion, suitable for the stresses of the transmission (chain, rear sprocket). The manufacturing control limits variations in tooth profile to reduce friction and premature wear, thus maintaining precise torque transmission and smooth chain engagement.
Compatible with a wide range of machines, this sprocket is particularly suitable for trail/cross and roadster practices where reliability is paramount. Examples of compatible models: HONDA XR 250 R (ME06), HONDA XL 250 R (MD11), HONDA CR 125 R (JE01).
Replaces the original 520 sprocket while offering the necessary robustness for both road and trail use.
