Renthal Front Sprocket: 

Renthal off-road front chainwheels are chosen by more factory motocross and supercross teams than any other chainwheel on the market today.

They are CNC machined from a cased hardened and core refined 655M13 nickel chromium steel.

Most models utilize mud grooves which are CNC machined into each tooth on both sides to allow mud to flow away from the key contact points between the chain and the chainwheel. This helps reduce wear and increases the drivetrain lifespan.

Certain models are available in a computer aided Ultralight design to further reduce weight while still maintaining its structural integrity.

JT Chain:

• Made from high carbon Japanese steel
• Surface hardened pins with rigid bushes for high wear resistance
