PBR 4666 Sprocket - 420 (Manufacturer Ref: 4666 38 F)
Replace the centerpiece of the rear transmission with this PBR sprocket designed for roadsters equipped with a 420 chain pitch. Designated by PBR as "aluminum," commercial specifications indicate that the sprocket is made of steel and comes in a black finish. Its 38-tooth design corresponds to the 420 standard for easy and reliable installation.
Ideal for replacement during a transmission service, this sprocket offers a suitable alternative for small displacement bikes and roadsters. It installs in place of the original sprocket with the same pitch and tooth count; be sure to follow the manufacturer's torque specifications and check the wear of the chain to ensure proper performance and even wear.
