Renthal Ultralight Front Sprockets

Renthal front chain-wheels are simply the finest front chain-wheel on the market today. Front chain-wheels feature a specially developed nickel-chrome-molybdenum steel which is case hardened and core refined to give the ultimate combination of strength and hardness. ULTRALIGHT chain wheels, Renthal have taken extra time to machine away surplus mass to reduce the mass of the chain-wheel. Chain-wheel mass reduction offers a two-fold gain. The overall mass of the machine is slightly reduced and the rotating mass of the gearbox is reduced, allowing faster engine spin-up and shorter over-run.

Renthal Ultralight Rear Sprockets

Rear Ultralight Sprockets: Manufactured to extremely tight tolerances from a special material developed to withstand the stress of Supercross, Motocross and Enduro. 7075-T6 aluminum alloy rear chainwheels are 66% lighter than steel, yet incredibly durable. Advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life. Combination of a very high strength base material and an exceptionally hard-wearing surface result in significantly increased chainwheel life. Self cleaning mud grooves help prevent dirt build-up.

Renthal Chains

R1 Works 120L Chain:
R1 Works Chain from Renthal® is a high-strength, non-O-ring chain with excellent impact load resistance designed specifically to withstand the stress found in offroad applications. This chain is the choice where a combination of high-strength, lightweight and maximum power transfer are important considerations. Shot-peened alloy steel side plates for high-tensile strength and maximum impact load resistance. Chamfered inner links to help reduce the chance of chain derailment. Extended bushings to reduce friction between inner- and outer-link plates. Shot-peened solid rollers and chromized pins help to extend service life. Gold-anodized side plates help prevent corrosion.
