Off Road Drive Chains


Renthal Chains
R1 Renthal Chains

R1 Works Chain


A premium high strength 520 chain with excellent impact load resistance, designed specifically to withstand the stress found in off road applications. This chain is the choice where a combination of high strength, light weight and maximum power transfer are important considerations.


The R1 Works Chain has the following features:

  •  Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance
  • Chamfered inner links to reduce the chance of chain derailment
  • Extended bushings to reduce friction between outer and inner link plates, maximizing power output
  • Chromised bearing pins for excellent resistance to wear
  • Gold colour side plates 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
R3-2 O-Ring Renthal Chains

R3-2 O-Ring Chain


A 520 o-ring chain designed for the extreme rigors of off road use.

  • Nitrile ‘O’ Rings extend chain life by retaining special vacuum injected grease inside the chain joint.
  • Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance
  • High carbon alloy steel bearing pins for excellent resistance to wear.
  • Gold colored side plates help prevent corrosion.
  • Pre stretched to enhance performance of the chain.
R4 ATV Renthal Chain

R4 ATV Chain


The R4 ATV Off Road Chain has the following features:

  • Patented z-ring seals dramatically increase the life of the chain
  • Larger diameter pins manufactured from specially enhanced steel improve the resistance to shock loads
  • A quad riveting process on each pin increases the tensile strength of the chain
  • Thicker inner and outer plates increase the fatigue life of the chain
RK Racing Chains

RK 420So Chains

RK 428SO Chains

420SO and 428SO


RK offers the best O-ring chains in the industry. All RK O-ring chains are constructed of hi-carbon alloy steel for strength and durability. RK utilizes Nitrile Butadiene O-rings to seal in lubrication and deliver smooth power with no O-ring drag or loss of horsepower.

RK G520MXZa Chains

GB520MXZ4  (And Non-Gold 520MXZ4)


MXZ4 is The Lightest Motocross Chain available on the market today. Made for the professional motocross racer, GB520MXZ4 is the next generation of motocross racing chains featuring RK's new deeper gold sideplates.
MXZ4 chains feature chromoly steel construction with seamless rollers and bushings, and oversized special alloy pins for added strength.


All components are heat treated using RK's exclusive HIT (Heat Induction Transfer) process, MXZ3 has a maximum tensile strength rated at 39.1 kN, weighs a mere 1.36Kg for 100 links, and can handle any MX race application from 125~500cc.


RK GB520EXW Chains

GB520EXW (And Non-Gold 520EXW)


GB520EXW is specifically designed for ATV/Quads and Off-Road vehicles and is the best high-speed, extreme heat, off-road performance chain available today. EXW chains were developed to survive the abrasive conditions that exist in hostile off-road environments. EXW features XW-ring seals composed of Nitrite Butadiene with three contact lips and two convex inner/outer stabilizers.


This means three lubrication pools to protect against high-speed abrasion, and the loss of lubricant under these extreme conditions.
