DescriptionJT. Steel Standard 703 - 520 Sprocket

Product details :

Features

Replace your sprocket with a simple and robust piece: the JT Sprockets JTR703.40 sprocket. Specifically designed for 520 chain transmissions, it is aimed at riders looking for a reliable maintenance part for their roadster or to modify the gearing.

Brand: JT Sprockets
Manufacturer Reference: JTR703.40
Material: steel (carbon C49)
Color: black
Number of Teeth: 40
Chain Pitch: 520
Type: standard

Made from C49 steel, this sprocket is designed to withstand the typical stresses of the road. Its standard profile fits original replacements and gearing adjustments to modify engine behavior (acceleration versus top speed). Ideal for regular maintenance, it installs easily in place of a worn part.

Always check the chain pitch (520) and the number of teeth required for your model before installation. Examples of compatible motorcycles: Aprilia Tuono 660 (2025), Aprilia Tuono 660 Factory (2025), and BMW G 650 X Moto ABS (2007).
