EK 420 H/Duty Motocross Chain Red 130L (20)

Take on muddy straights and high-torque sprints with the EK 420 H/Duty Motocross Chain in striking red. Built for performance-minded riders, this 130-link chain is engineered to handle the brutal demands of motocross and enduro riding on 420-class setups, delivering reliable power delivery when it matters most.

• 
  130-link length for a precise fit — tailored to pair with standard 420 sprockets and most motocross bikes, ensuring an optimal chainline and efficient power transfer from crank to rear wheel.
• 
  Heavy-duty construction — reinforced inner plates and robust pins designed to withstand high-torque launches, aggressive throttle control, and the rough terrain typical of professional and amateur tracks.
• 
  X-ring seals for durability — advanced sealing minimizes mud, water, and grit ingress while reducing friction, helping cut chain stretch and extend service intervals in demanding conditions.
• 
  Vibrant red outer plates — high-visibility color for quick inspection on track days and a signature look that unmistakably marks your ride as ready for race-level performance.
• 
  Heat-treated steel with superior coating — engineered for long life in mud, sand, and grit; the coating protects against corrosion and maintains performance across rides and seasons.
• 
  PowerLink master link — enables fast, tool-free installation and field maintenance, so you can swap chains or perform quick adjustments at the track or in the pits.
• 
  Low-friction, low-maintenance performance — designed to hold lubrication longer and resist creep under high RPM, keeping tension stable and power transfer smooth mile after mile.

Who this is for

Ideal for riders who demand durability and predictability from their drivetrain: competitive motocross racers, weekend warriors hitting muddy tracks, and riders upgrading to a reliable, long-lasting 420-pitch chain for off-road adventures. If you ride a motocross bike configured for a 420 chain and seek fewer pinch points, faster field service, and a standout red aesthetic, this EK chain is designed for you.

Use cases and benefits

• Racing and track days where aggressive riding and quick accelerations demand a chain that won’t quit.

• Maintenance-friendly setups with the PowerLink for rapid chain swaps after race weekends.

Maintenance and tips

• Regularly clean and lubricate after riding in wet or muddy conditions to maximize the life of the X-ring seals.
• Check chain tension and wear after every race or long ride; replace the chain and sprockets when stretch or wear becomes noticeable to preserve drivetrain performance.
• Keep an eye on chain alignment and sprocket condition to prevent uneven wear and ensure smooth power transfer.
