Regina 520 ZRT Z-Ring Chain

Regina chains are the exlusive choice of extreme off-road rider Malcolm Smith because of their superior performance and incredible wear resistance.

The "Z-Ring" Chain uses an exlusive, patented Z-shape ring that seals in the factory injected lubrication at four points to reduce rolling resistance. Gold outer plates with high carbon alloy pins, solid bushings, shot peened solid rollers and plates for an unbelievable tensile strength, lower friction and higher wear resistance.

- Regina O-Ring 520 ZRH chain is suitable for up to 500cc MX use and 650cc Enduro use.
- Average tensile strength of 7,650lbs.
- 120 Links

NOTE: For some models the optional countershaft spacer may be needed for proper chain-to-engine case spacing. If your CRF model requires a narrow chain we highly recommend the DID VT2 chain.
