All motorcycle drive chains require maintenance! Although all our ‘O’ ring and ‘X’ ring chains are sealed with internal lubrication when manufactured, like all chains, they still require external lubrication on a regular basis. Be sure to lubricate with chain lube and not something wax based approximately every 300 miles, or more often if conditions require. All chains used in dirty applications require cleaning and lubrication even more regularly.
Beware - lack of maintenance can lead to premature wear and even failure.
