PBR Standard Steel Sprocket 727 - 520 (Manufacturer reference: 727 12 18NC)
Drawing from PBR's experience in competition, this 12-tooth front sprocket is made from a carefully crafted 18NCD5 steel alloy designed for the transmission of off-road motorcycles and roadsters. Built to withstand the loads and stresses of the chain, it is aimed at motocross, quad, and roadster riders looking for a robust and reliable component for their drivetrain.
The PBR manufacturing process is strict: treatment and finishing that limit abrasion and corrosion, optimized tooth design to reduce friction and ensure stable chain behavior. This part is suitable for original replacement on several models (e.g., HUSQVARNA TE 511, HYOSUNG TE 450 RAPIER, BMW G 450 X) and is easy to install during a transmission service.
Choose this sprocket if you want a component suited for intensive use, with a focus on longevity and consistency of the tooth profile. Ideal for maintaining engine torque, chain smoothness, and the safety of your rides.
