This Tsubaki 520 RQ1 X-ring chain is engineered for Harley-Davidson riders seeking a durable final drive for chain-conversion projects or custom frame applications.

Utilizing X-ring seals, this chain retains grease within the bushings to prevent premature wear and ensure smooth power delivery to the rear wheel. The steel construction and precision-engineered rollers provide the resilience required for high-mileage touring or aggressive street riding. Supplied with 128 links, this chain provides extra length for extended swingarms or unique gearing setups. Tsubaki’s reputation for engineering excellence makes this a dependable choice for any drivetrain overhaul.
