Renthal Dirtbike Rear Sprocket Yamaha YZ450F 2003-2005

Renthal Off Road Rear Sprockets are manufactured from a specially enhanced 7075T6 aluminum alloy produced especially for sprockets. This particular alloy has excellent resistance to wear combined with very high tensile strenght. Renthal sprockets are designed to withstand the rigors of Motorcross and Supercross racing. Renthal Off Road Rear Sprockets feature:

• Precision CNC matching for unequaled accuracy of fit, tooth profile and concentricity
• An "Ultralight" design reducing unnecessary weight while retaining maximum strength
• Aluminum (one-third the weight of steel) which reduces the power required to accelerate and brake unsprung revolving weight, resulting in improved race performance
• Self-cleaning mud grooves in between each tooth
• A silver etched finish, resisting dirt build-up
