The REGINA 420 RX3 drive chain is engineered for demanding off-road riding, delivering a strong balance of durability, reduced weight, and reliable power transfer. This 110-link chain is designed for off-road motorcycles and compatible applications using a 420 chain size. Its construction is intended to withstand severe riding stresses while maintaining smooth, consistent performance in challenging terrain.
Specially shaped bushings and chromized pins help reduce chain elongation and improve resistance to wear. Larger-diameter alloy carbon steel pins and thicker plates are shot-peened to increase tensile strength and fatigue resistance. Extended bushings and solid rollers add durability, while beveled inner links help improve sprocket engagement, including under difficult off-road conditions. A clip-type connecting link is included for installation.
This REGINA 420 RX3 chain is identified by manufacturer part number 124RX3/003 and vendor part number 124RX3/003. Confirm that your motorcycle or powersports application uses a 420-size chain with a 110-link configuration before installation. Proper sprocket compatibility, alignment, lubrication, and adjustment are recommended for dependable service life and performance.
