Rear Renthal Alloy Sprocket: 

• Renthal Ultralight Rear

  Renthal Ultralight™ rear chainwheels are manufactured to extremely tight tolerances from  7075 T6 aluminium alloy which is 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life.

  Renthal's combination of a high strength base material and exceptionally hardwearing surface result in significantly increased chainwheel life over other brands.

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
• Industry leading tensile strength, proven stronger than DID equivalent
• Split link for easy fitment and application

Power Transfer heavy duty drive chain from JT. Combining performance, strength, durability at a competitive price. Created using leading manufacturing processes and only from the highest grade of special steel alloys. Race developed for ultimate results.
