55212520130 520 RQ1 X-ring chain, 130 links

The Tsubaki 520 RQ1 X-ring chain is a performance-oriented final drive component suitable for Harley-Davidson motorcycles utilizing a 520 chain conversion. This chain employs X-ring seals that create four points of contact to trap lubricant and keep out road grime, resulting in lower operating temperatures and a longer lifespan compared to traditional designs. The 130-link length is ideal for custom builds with long wheelbases or large rear sprockets where standard chain lengths fall short. Built from robust steel with a focus on tensile strength, it manages the power pulses of a V-twin engine with ease. Tsubaki remains a preferred brand for riders who demand precision manufacturing and long-term reliability in their drivetrain components.
