I have brand new CNC machined cam chain rollers for CB/CL/SL motorcycles. Upper roller is a sprocket, lower is a smooth roller. Each have high quality needle roller bearings pressed into them. Upper roller comes with a deformable rivet. Material is chromolly steel. See the following links for purchase.
