PBR Standard Steel Sprocket 402 - 520 (Manufacturer part number: 402 16 18NC)

Designed by PBR based on experience gained in competition, this front sprocket made of steel is aimed at demanding riders in the Cross and Roadster worlds. Its design incorporates an 18NCD5 steel alloy, a material recognized for its mechanical strength and resistance to corrosion and abrasion.

• Material: steel (18NCD5 alloy)
• Number of teeth: 16
• Chain pitch: 520
• Type / version: 402 – Standard

The tooth profile and surface treatment are carried out according to a strict manufacturing process to ensure consistent geometry and controlled tolerances. The result: smooth interaction with the chain, reduced friction, and more consistent drive — crucial points for the longevity of the transmission.

This sprocket fits many 650 cc trail/road and light enduro models; among the common compatible models are the BMW G 650 GS, the Husqvarna TR 650 Terra, and the Aprilia Pegaso 650. As a standard replacement part, it can be used for both on-road and off-road applications when a 520 chain configuration is required.
