A premium, high strength, light weight, 520 non 'O'-ring chain with excellent impact load resistance. Designed specifically for Motocross and Supercross racing applications. This chain is the choice where a combination of high strength, light weight and maximum power transfer are important considerations.

• Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
• Chamferedinner links to reduce the chance of chain derailment.
• Extended bushings to reduce friction between outer and inner link plates, maximising power output.
• Chromised bearing pins for excellent resistance to wear, specifically under off road riding conditions.
• Special finish: gold coloured side plates to help prevent corrosion
• Most perfectly matched chain for Renthal Chainwheels allowing maximum power at the rear wheel. This also extends the life of both the chain and chainwheels.

A premium, long-life, high strength, 'O'-ring chain. This chain features nitrile 'O'-rings, which retain a special vacuum injected grease around the critical pin and bush area. Renthal R3 chain is the choice where a combination of long life, high strength, light weight and excellent impact load resistance are important considerations. Designed as a multi purpose chain for both off-road and road applications up to 650cc.

• Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
• Nitrile 'O'-rings which retain a special vacuum injected grease around the critical pin and bush area, which extends the life of the chain.
• High carbon alloy steel bearing pins for excellent resistance to wear, for both road and off road riding conditions.
• Special finish: gold coloured side plates and copper coloured rollers to help prevent corrosion.
• Most perfectly matched chain for Renthal Chainwheels allowing maximum power at the rear wheel. This also extends the life of both the chain and chainwheels.

Renthal Works 420R1 Chain

This new Non O-ring 420 chain has been designed specifically for today’s higher-powered Mini Motocross racing machines that use a 420 chain, up to 100cc capacity. This chain is a Mini version of the very popular Renthal Works 520R1 Chain.

• Shot-peened alloy steel side plates for high tensile strength and maximum load resistance
• Extended bushings to reduce friction between outer and inner link plates, maximising power output.
• Chromised bearing pins for excellent resistance to wear, specifically under off road riding conditions.
• Pre-formed bushings, which distribute the load evenly, resulting in even greater chain life.
• Gold coloured side plates.
• Copper coloured rollers.
• Average tensile strength 20,500N (4,608 Lb.)

Renthal 428R1 Works Chain

This new Non O-ring 428 chain has been designed specifically for today’s higher-powered Mini Motocross racing machines that use a 428 chain, up to 100cc capacity.

• Shot-peened alloy steel side plates for high tensile strength and maximum load resistance
• Extended bushings to reduce friction between outer and inner link plates, maximising power output
• Case hardened alloy steel bearing pins for maximum resistance to wear.
• Gold coloured side plates.
• Copper coloured rollers.
• Average tensile strength 22,000N (4,946 Lb.)
