EK 428 H/Duty Motocross Blue Chain 136L (20)

Meet the EK 428 H/Duty Motocross Blue Chain 136L — a purpose-built drive link engineered for the rough, high-torque world of motocross and aggressive off-road riding. With a 428 pitch and a generous 136-link length, this chain is designed to fit a wide range of motocross setups, giving you dependable power transfer when you need it most.

Why this chain stands out on the track and in the workshop:

• 
  Heavy-duty performance built to handle the brutal demands of fast exits, hard landings, and muddy, grainy terrain without staking or stretching prematurely.
• 
  Vivid blue outer plates for easy visual inspection and a distinctive, race-ready look that helps you spot wear or misalignment at a glance.
• 
  Reliable durability designed to resist grit, spray, and grime that can shorten chain life, so you spend less time wrenching and more time riding.
• 
  Consistent sizing with precise pitch and rivet fit, which translates to smoother power delivery and less sprocket wear over time.
• 
  Versatile length 136 links provides broad compatibility with common motocross gear ratios, helping you dial in acceleration and top speed more predictably.

Built for riders who demand more

• Racers who push aggressively off the line and through tight chicanes will appreciate steady performance lap after lap.
• Enduro and trail riders who need a rugged chain that resists mud and cross-country grit.
• Dedicated enthusiasts upgrading from standard chains who want a visibly durable, race-ready look.

What you can expect in practice

• Improved power transfer with consistent engagement between chain and sprockets, reducing drivetrain hiccups during shifts and throttle bursts.
• Longer service intervals in gritty environments thanks to protective finish and robust construction.
• Better visibility for quick inspections—blue plates make it easier to spot kinks, corrosion, or wear before they become issues.

Installation and care tips

• Designed for standard 428 chain sprockets; verify fit for your bike’s chainline and sprocket count, with 136 links as the reference length.
• Install using a proper chain tool and master link to ensure a secure rivet and a clean, reliable closure.
• Lubricate regularly with a motorcycle-specific chain lubricant, and rinse or wipe after muddy rides to prevent abrasive buildup.
• Check tension and overall condition after the first few outings, then at regular intervals to maintain optimal performance and minimize wear on sprockets.

Choose the EK 428 H/Duty Motocross Blue Chain 136L for a combination of rugged durability, clear on-bike visibility, and dependable performance when the track gets muddy and the laps get faster. It’s the thoughtful choice for riders who pair relentless riding with reliable, long-lasting drivetrain integrity.
