EK Chain 525SRX2120G SRX2 525 QX-Ring Motorcycle Chain 120 Links Gold

The EK Chain 525 SRX2 Series QX-Ring Chain is a premium motorcycle drive chain engineered for street, touring, and performance riding. Featuring EK's advanced Quadra X-Ring (QX-Ring) sealing technology, this 525-pitch chain delivers measurably better friction reduction, longer service life, and improved power delivery compared to standard O-ring chains — making it an ideal OEM replacement or performance upgrade.

Key Features:

• Quadra X-Ring (QX-Ring) Technology: Four-point contact seal design reduces friction by up to 40% compared to traditional O-ring chains, allowing more power to reach the rear wheel
• Extended Chain Life: Laboratory testing confirms QX-Ring chains last up to 50% longer — approximately 1.5 to 2 times the lifespan of a standard O-ring chain
• Lightening Holes: Weight-saving holes drilled into every other side plate provide a 3% reduction in rotating mass without compromising tensile strength, improving throttle response
• Gold Zinc Finish: Durable gold plated finish for corrosion resistance and visual appeal
• 120 Links: 120-link count suitable for a wide range of street and sport-touring applications
• Tensile Strength: Rated at approximately 9,000 lbs average tensile strength
