PBR Standard steel sprocket - 520, 40 teeth
This PBR sprocket, made from an 18NCD5 steel alloy, is aimed at riders looking for a reliable transmission part for their roadster. With its 40 teeth and 520 chain pitch, it fits corresponding chains and sprockets to ensure a robust wheel-engine connection. The black finish reduces glare and facilitates aesthetic integration across a wide range of motorcycles.
Drawing on PBR's experience in competition, this sprocket benefits from a strict manufacturing process aimed at reducing friction and limiting abrasion. Ideal for maintenance or preparing a transmission, it is particularly suitable for the following models: KAWASAKI NINJA 500 SE (2026), YAMAHA R9 (2025), and SUZUKI GSX-R 1000 R ABS (2021), as well as other motorcycles compatible with the 520 pitch.
Replace your worn sprocket with this PBR model to regain sharp tooth engagement and precise fitting. Check compatibility with your model before installation.
