JT SPROCKETS Standard Steel Sprocket - 520 (JTR5.40)
Designed for replacement or a change in gearing, this JT Sprockets sprocket is aimed at riders looking for a robust and easy-to-install transmission part. Made from steel (carbon C49), it meets the specifications for drive trains equipped with a 520 pitch chain and offers a standard number of teeth for a good compromise between acceleration and top speed.
Suitable for roadster environments and standard transmissions, this sprocket is compatible with many models using the 520 pitch. Examples of affected motorcycles include: BMW G 310 GS (2025), Husqvarna TR 650 Terra ABS (2014), and Aprilia Pegaso 650 (2013) — however, please check the exact original reference before purchase.
Ideal for regular maintenance or a gearing modification, the JTR5.40 replaces a standard 520 sprocket. For safe installation, check the condition of the chain, sprockets, and bearings before fitting.
