This kit is suitable for models from 1999-2024 and includes: 

x1 Renthal Blue, Silver or Black Alloy Sprocket 

x1 Renthal R1 Heavy Duty Chain 118 Links Long

x1 Renthal Front Sprocket


Rear Sprocket: 

Renthal UltraLight Rear Chainwheels are CNC machined in Manchester, UK from 7075 T6 aluminum to extremely tight tolerances, 66% lighter than steel. Computer engineered and tested to ensure a precise fitment, concentricity and load dispersion with tooth profiling to provide maximum power transfer.

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.

Chain:  


Renthal R1 Chain is a high-performance, lightweight, low-friction, non o-ring chain specifically engineered for racing at the highest levels. The R1 Chain has high resistance to elongation and severe abrupt stresses encountered in MX and SX racing. This is achieved by manipulating raw material composition to increase tensile strength and yield strength. Each R1 Works Chain features chamfered inner links, extended bushings, shot-peened outer plates and manufacturing processes. This reduces weight in a durable and safe motocross chain that can be trusted to deliver maximum power output in any condition.
