Note
Please confirm your vehicle's current axle diameter (12mm) and sprocket pitch (420) against these technical specifications before purchase. Because wheel alignment, drivetrain tension, and braking systems are critical for operator safety, we highly recommend that this propulsion wheel and sprocket assembly be installed by a professional motorcycle technician or an experienced mechanic.
