520MX6 14/49 reinforced chain kit with a standard steel sprocket, a balanced MX setup that prioritizes versatility in terms of traction, acceleration, and gear ratio.
AFAM offers this reinforced 520MX6 chain kit for the SUZUKI RMZ 450 cc, featuring a 116-link A520MX6-GG chain, a standard 14-tooth steel sprocket (part 22406), and a standard 49-tooth steel rear sprocket (part 14203). The chain features a gold/gold finish, a 520 pitch, and a reinforced design intended for MX use. The 14/49 gear ratio—equal to 3.50—offers a balance between acceleration and top speed, with a slightly longer gear ratio than a 14/50 setup. The 14203 sprocket, made of quenched C45 steel, provides good resistance to the repeated stresses of the drivetrain. The combination thus prioritizes the robustness of the steel sprocket while maintaining a gear ratio suited to changes in pace on the track.
