EK Chain 520Z3D120G 520 Z 3D Premium Motorcycle Drive Chain 120 Links Gold

The EK Chain 520 Z3D is a top-tier non-O-ring motorcycle drive chain engineered for riders who demand peak performance without sacrificing style. Featuring EK's signature 3D curved outer plate design, this 520-pitch chain delivers exceptional stiffness and power transfer while shaving critical weight compared to conventional high-performance chains.

Key Features:

• 3D Precision-Forged Outer Plates: Curved three-dimensional plate shape maximizes stiffness for superior power delivery to the rear wheel
• Dimpled Outer Plates: Additional structural reinforcement adds strength without added weight
• Lightening Holes in Inner Plates & Pins: Strategically placed cutouts reduce overall chain mass while maintaining structural integrity and helping to shed mud and dissipate heat
• Edge-Cut Inner Plates: Reduces friction and allows for smoother, more efficient engagement with the sprocket
• Chromium Carbide Pin Coating: Increases surface hardness and reduces chain wear for extended service life
• 9,400 lb. Tensile Strength: Rated for motorcycles up to 1000cc
• Gold Finish: Bright gold color adds a premium look to the drivetrain

The EK 520 Z3D is the ideal choice for off-road and performance riding applications — including Motocross, Enduro, Supermoto, and Supersport — where a lightweight, high-strength chain is critical. The 520 pitch weighs approximately 3.64 lbs per 100 links, making it one of the lightest options in the premium chain segment.
