This sprocket installs in place of the original to restore compliant gearing or modify the character of the motorcycle by adjusting the final ratio. The black finish reduces glare and facilitates visual integration on a dark swingarm. The tooth profile is machined for a clean engagement with a 428 chain; check the condition of the sprocket and chain during installation to ensure even wear.
