REGINA 520 ZRA Black Dual is a high-mileage, low-stretch drive chain engineered for demanding off-road and street use. Z-Ring sealing and factory pre-stretching help extend lubrication intervals and reduce elongation.
REGINA 520 ZRA Drive Chain Black Dual is built for riders who want consistent power transfer and long service life with less maintenance. Manufactured with high-carbon alloy steel components and strengthened with shot-peened plates, pins and rollers, it delivers excellent fatigue resistance for hard riding conditions.
Thanks to performance-enhancing pre-stretching and REGINA’s Z-Ring seals, this chain is designed to provide high mileage, reduced elongation and extended lubrication intervals. Laser marking on the outer plates helps identify dimensions, model and origin—useful for service work and correct fitment.
