RFX FXRS 50-48 ALRD Armalite Rear Sprocket 48 Teeth for KTM, Husqvarna, Gas Gas

The RFX FXRS 50-48 ALRD Armalite Rear Sprocket is engineered for high-performance motorcycle applications, offering a combination of lightweight design and durability. Constructed from CNC-machined 7075 aerospace-grade aluminum for the inner ring, this sprocket provides exceptional strength while remaining lightweight. The outer ring features high-carbon steel (HCS) for increased wear resistance, ensuring long-lasting use under demanding riding conditions. The sprocket's design incorporates a hex-drive location between the inner and outer rings, facilitating secure attachment and precise alignment.

CAD-designed profile enhances the sprocket's lightness without sacrificing strength, optimizing power transfer and reducing rider fatigue. New mud-clearing grooves are integrated into the design to minimize debris buildup and reduce wear over time, maintaining optimal performance in muddy or challenging environments. The rigid construction increases torsional strength, providing reliable power transmission during aggressive riding maneuvers. The sprocket is finished with a vibrant red anodized coating, offering a factory-style appearance that complements KTM, Husqvarna, and Gas Gas bikes. Whether replacing worn components or upgrading for better performance, this sprocket is built to meet the demands of motocross, trail riding, and other off-road disciplines.
