PBR Steel Standard 1248 - 520 Gearbox output pinionRef : PBR00591A / 1077516004

Designed by PBR and stemming from experience gained in competition, this standard steel sprocket offers a robust solution for the transmission of your trail, cross, or quad bike. Compact and reliable, it is aimed at demanding riders who seek a replacement part that strictly adheres to original specifications.

• Manufacturer reference: 1248 14 18NC
• Type: Standard sprocket 1248
• Material: Steel (18NCD5 alloy)
• Number of teeth: 14
• Chain pitch: 520

The 18NCD5 steel alloy used ensures excellent resistance to corrosion and abrasion, resulting from a very strict manufacturing process at PBR. The geometry of the teeth and the finish aim to limit friction with the chain for controlled wear and a clean transmission.

Versatile, this sprocket fits 520 pitch transmissions and is suitable for cross, roadster, or quad machines. It is particularly relevant for users of 500 cc single-cylinder bikes and other models equipped with the 520 pitch — for example, machines similar to the STARK FUTURE VARG EX, HUSQVARNA FE 501, or KTM 500 EXC-F SIX DAYS (depending on installation and manufacturer compatibility).

Replace your worn sprocket with a PBR part to restore reliable transmission performance and simple installation, without compromising on material quality.
