Made from 2024AL (same alloy used by Factory Teams), this strong, elastic material keeps them compliant with the suspension and chassis. 21mm Offset recommended for Motocross (crf250r) (MX); Supercross (SX); Arenacross (AX) (stock offset for 48mm forks is 20mm, for 49mm forks is 22). Use our Over-sized bar mounts to add strength, torsional rigidity and handlebar adjustability - 3mm forward or 3mm back of stock (can also be used with stock bar mounts).
