PBR standard steel sprocket 517 in pitch 428, designed for demanding riders looking for a robust and reliable transmission part. Drawing from PBR's competitive experience, this 13-tooth sprocket is made from high-quality 18NCD5 steel alloy, engineered to withstand the stresses of off-road as well as road use.
The design and surface treatment provide good resistance to corrosion and abrasion while optimizing engagement consistency to minimize friction between the sprocket and chain. Ideal for replacing the original 13-tooth sprocket on 428 pitch transmissions, it fits well on both motocross machines and roadsters.
Compatible model examples: KAWASAKI ELIMINATOR 125 (BN125A), KAWASAKI KMX 125 (KMX125B), KAWASAKI KDX 125 SR (KDX125B). Check the reference of your original sprocket before installation.
