520MX6 13/51 reinforced chain kit with a hard-anodized Ultra-Light sprocket—a short MX configuration that prioritizes traction and acceleration while reducing the sprocket’s weight.
AFAM offers this reinforced 520MX6 chain kit for the TM RACING MX 250 cc, featuring a 116-link A520MX6-GG chain, a standard 13-tooth steel sprocket (94312), and a 51-tooth aluminum rear sprocket (93314). The chain features a gold/gold finish and reinforced construction designed for MX use. The 13/51 gear ratio (3.92) provides a short final drive ratio that enhances acceleration, traction, and acceleration out of corners. The hard-anodized Ultra-Light sprocket combines reduced weight with increased resistance to friction and wear. This configuration pairs a standard steel sprocket with a lightweight aluminum sprocket treated to withstand the repeated stresses of motocross.
