Regina 520 ZRA Black Dual Series 120L Black Chain

REGINA BLACK DUAL SERIES

Regina started the production of motorcycle chains in 1939, with exceptional results at a global level with over 340 world championships. Regina works closely with manufacturers to ensure they are innovating and meeting the needs of the forever changing motorcycles.

BLACK DUAL chains have a natural steel colour and are available in 520 and 525 dimensions only. Manufactured with high carbon alloy steel components, solid bushings and rollers, shot-peened plates, pins and rollers to reach high fatigue resistance. Laser marking on outer plates to identify dimension, model and origin. Submitted to performance-enhancing pre-stretching, also thanks to the Z-Ring seals, BLACK DUAL chains ensure high mileage, reduced elongation and extended lubrication intervals.
