RFX FXRS 31-52 99BU aluminum rear sprocket is designed for off-road motorcycles, providing a lightweight yet strong component for optimal power transfer. Constructed from CNC machined 7075 aerospace aluminum, it offers high resistance to impact and wear. The sprocket features chamfered weight-reducing cutouts to decrease rotational mass, enhancing acceleration and handling. Mud clearing grooves help prolong sprocket life by reducing debris buildup, making it suitable for muddy or dusty conditions. The kit includes the sprocket with a 2-tone anodized and polished finish for a factory-style appearance, complemented by laser-etched RFX branding for authenticity. Strengthening gussets add rigidity to prevent deformation under load, ensuring consistent performance during aggressive riding. The combination of lightweight design and sturdy construction makes this sprocket a reliable upgrade for motocross and off-road bikes.
