EK 520 QX-Ring Metallic Blue Chain 120L (10) (RAS)

Meet the EK 520 QX-Ring Metallic Blue Chain 120L (10) (RAS) — a purpose-built 520 chain that blends elite engineering with striking style. Designed for riders who refuse to compromise between durability, smooth operation, and looks, this chain delivers reliable power transfer ride after ride.

What makes it stand out? the QX-Ring technology at the heart of this chain. The four-point contact X-ring seals sit precisely where the chain meets the rollers, dramatically reducing friction and shield­ing the internal components from dirt and debris. The result is extended chain life, steadier performance, and fewer maintenance interruptions on daily commutes, weekend canyon runs, or back‑road scrambles.

Why riders choose the EK 520 QX-Ring Metallic Blue

• Advanced sealing with QX-Ring: Four-point contact seals reduce power-robbing drag and slow wear, delivering smoother shifts and longer chain life compared with standard sealed designs.
• Blue metallic coating: A durable, corrosion‑resistant finish that not only looks bold on the bike but also helps protect against the elements for longer service life.
• 120 links per chain: A versatile length that fits a wide range of 520 drivetrain setups; designed to be cut to the perfect fit for your motorcycle’s front and rear sprockets.
• Strength you can rely on: Heat-treated steel core provides high tensile strength to handle spirited riding, aggressive acceleration, and everyday use without sag or stretch early in the life cycle.
• Packs for riders who demand convenience: Sold as a 10-pack, giving you multiple chains ready to refresh an entire drivetrain or keep spares on hand for future maintenance.

Real-world use cases and benefits

• Daily riders: Replacing a worn chain with a QX-Ring chain reduces drivetrain drag, improving throttle response and fuel efficiency over time.
• Sport/naked bikes and sport-tourers: The combination of strength, seal protection, and a vivid blue finish stands up to high-rev, splash-prone conditions while keeping aesthetics sharp.
• Track day and spirited canyon rides: Consistent power transfer and reduced friction mean crisper shifting and predictable performance under demanding riding styles.
• Maintenance-conscious riders: Longer intervals between cleanings and lube due to effective sealing translate to less downtime and more miles between service.

Installation and care tips

• Use a proper rivet or chain tool for accurate fitment and correct master link compression.
• After installation, verify correct chain tension and aim for smooth, even motion around the sprockets without binding.
• Apply a quality motorcycle chain lubricant after rides in wet or dirty conditions; wipe away excess to avoid fling-off.
• Inspect regularly for kinks, stiff links, and signs of wear; replace the chain as a matched pair with a new sprocket to maximize life.

Whether you’re upgrading an aging drivetrain, stocking up for routine maintenance, or outfitting a new build, the EK 520 QX-Ring Metallic Blue Chain 120L (10) (RAS) combines robust engineering with a standout finish. It’s a drivetrain upgrade that translates into real-world benefits: smoother power delivery, longer life between services, and a distinctive look that turns heads as you ride.
