Renthal 224U-520-52GPBK Engine Timing Idler Sprocket

Renthal sprockets are CNC-machined (not stamped) and feature a computer-aided Ultra light design to reduce unsprung weight and increase power transfer Rear sprockets are made from high-strength, specially enhanced 7075 T-6 aluminum - 33% lighter than steel - to further reduce weight and increase power transfer without sacrificing strength Rear sprockets also feature special tooth profile that allows the chain to roll easily on and off the sprocket for longer wear, less noise and more power All Renthal rear sprockets are hard anodized
