RFX FXRS 31-51 99BU aluminum rear sprocket is designed for off-road and motocross applications, featuring a 51-tooth configuration for optimal power transfer and acceleration. Crafted from CNC machined 7075 aerospace aluminum, it offers strength and lightweight performance for demanding riding conditions.
The sprocket includes strengthening gussets that enhance structural integrity under high torque loads. Chamfered weight-reducing cutouts not only decrease overall weight but also contribute to improved rotational response. Mud clearing grooves help maintain sprocket longevity by preventing mud buildup, ensuring consistent performance across various terrains.
Finished with a two-tone anodized and polished surface, this sprocket provides a factory bike aesthetic while resisting corrosion. The laser-etched RFX logo adds a touch of branding and style, making it a suitable upgrade for riders seeking durability and performance in a visually appealing package.
