EK 520 RR/SM SX-Ring Narrow Race Chain 120L - Gold (10)

Meet the EK 520 RR/SM SX-Ring Narrow Race Chain 120L in Gold — the race-grade chain built to push every ride a step further. Designed for 520-drive systems, this chain combines precision engineering with a striking gold finish that doesn’t just look fast, it performs that way in real-world conditions.

The SX-Ring technology sets this chain apart. Its sealed, narrow-profile design minimizes friction and drivetrain drag, delivering smoother shifts, crisper throttle response, and more efficient power transfer from the crank to the rear wheel. That means quicker acceleration, steadier mid-range torque, and a more confident feel on twisty roads or on the track.

• 
  SX-Ring sealing reduces dirt intrusion and wear, extending chain life even under aggressive riding styles.
• 
  Narrow race profile lowers weight and improves shifting precision without sacrificing strength for high-torque launches.
• 
  Gold finish combines durability with a premium, head-turning look that stays vibrant in diverse riding conditions.
• 
  120 links provide the right length for most 520-equipped bikes, balancing rigidity and flexibility for dependable performance.
• 
  Race-ready performance engineered to handle track days, canyon rides, and spirited street sessions with consistent power delivery and reduced chain stretch.

This chain is ideal for riders who demand a premium drive train upgrade: sport bike enthusiasts, track-day participants, and anyone running a 520 chain drive who wants enhanced efficiency, longer service intervals, and a striking aesthetic. If you’re upgrading from a standard chain, expect smoother shifts, quieter operation, and a more immediate response to throttle input, all while maintaining robust durability in demanding riding conditions.

Practical tips for optimal results: verify your bike uses a 520 chain, choose the correct chain length for your sprockets, and use a rivet/master link compatible with your setup. Regularly inspect for kinks or stiff links, clean and lubricate with a lubricant suitable for sealed chains, and maintain proper tension according to your manufacturer’s spec to maximize the life of your EK 520 RR/SM SX-Ring Narrow Race Chain 120L in Gold.

Upgrade your drive train with EK’s race-proven engineering — add the 520 RR/SM SX-Ring Narrow Race Chain 120L in Gold to your cart and feel the difference on every ride.
