DID 520VX3 is a high-performance sealed X-Ring 520 drive chain designed for low friction, strong durability and crisp throttle response across a wide range of bikes. Improved X-ring retention helps extend seal life in tough riding conditions.
DID’s 520VX3 (VX Series) drive chain is built for riders who want a smooth, responsive drivetrain without sacrificing durability. Thanks to its patented low-friction X-Ring design and highly rigid pins, the chain minimizes flex under load—helping deliver more consistent power transfer and sharper throttle response. The VX3 also features improved seal performance through increased X-ring retention and durability, making it a reliable choice for demanding street and off-road use.
If you ride in dust, mud or mixed conditions, a sealed X-Ring chain helps keep lubrication where it belongs and reduces wear compared to non-sealed options—so you spend less time adjusting and replacing drivetrain parts and more time riding.
