JT SPROCKETS Standard Steel Sprocket 245/3 - 520 (Manufacturer part number: JTR245/3.43) — a replacement sprocket designed for riders looking for a simple, robust part that complies with the 520 pitch. Ideal for original replacement or for modifying the gearing of your secondary transmission to achieve better chain performance.
This sprocket installs on the rear wheel as a direct replacement for compatible references with a 520 pitch. The choice of C49 steel provides the mechanical characteristics suited for the common demands of the transmission: gradual wear, contact with the pinion, and chain guidance. Standard installation and checks (chain tension, alignment, and hub tightening) are recommended to ensure safe operation.
Some common applications (examples): HONDA FMX 650 FUNMOTO (RD12), HONDA FX 650 VIGOR (RD09), HONDA SLR 650 (RD09). Please check compatibility with your machine before ordering.
