Regina PROFESSIONAL chains are constantly refined to meet the highest standards of strength, longevity, and reliability in the most demanding karting environments.
This 126 RX3 chain features special “X”-type chromized pins and linkplates with a specific bevel to ensure optimal sprocket engagement, even in high-stress setups like shifter karts. All Professional series chains come pre-stressed and include antikink extended bushings along with shot-peened rollers and plates to significantly improve fatigue strength.
A master link is included for easy installation. Note: Packaging may be labeled “Professional Cross Supermotard,” but it is the same as the standard Professional version. Chain weight (60L) is 21oz.
