Renthal Grooved FrontSprockets

Renthal’s chainwheels are precision CNC-machined to extremely tight tolerances to give the ultimate combination of strength and light weight. Features specially developed Nickel Chrome steel, case hardened core refined to give the ultimate combination of strength and hardness. Certain models are available in the ultralight design.

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.

R3SRS 120L Chain:
Renthal R3-3 chains are specially developed utilising Renthal’s SRS (self-regulating seals) technology to increase longevity. The SRS is pre-loaded during assembly, creating a spring effect. As a chain wears, conventional O-rings and X-rings loosen their seal whereas the SRS has the inherent ability to regulate a constant sealing pressure against the side plates throughout the life of the chain, increasing the service life of the chain.
