At DMG Motorsports, we present the D.I.D 520ATV2 X-Ring Sealed ATV Chain — the gold standard in ATV drive chains for riders who demand uncompromising performance. Part of D.I.D's exclusive Racing Series, this 520-pitch chain is engineered specifically for the brutal demands of ATV and quad racing. Built from the ground up with thicker reinforced sideplates, a special steel alloy construction, and D.I.D's patented X-Ring sealing technology, the 520ATV2 is trusted by top ATVMX competitors and backed by decades of Japanese precision manufacturing. Whether you're hammering through moto tracks or blasting trail, this chain is ready to keep up — lap after lap, season after season. It comes complete with a gold clip-style master link for straightforward installation.

Features:

• Patented X-Ring Seal Technology: Four-contact-point X-rings twist between side plates to disperse pressure, minimizing power loss and delivering half the friction of a standard O-ring chain — keeping dirt out and lubrication locked in.
• Thicker Reinforced Sideplates: Engineered for quad racing with a 7% weight saving, 10% greater strength, and 8% longer wear resistance versus standard designs.
• Special Steel Alloy Construction: Guards against heat cracking in cold weather caused by the severe heating and cooling cycles experienced during competition.
• Exceptional Wear Resistance: Delivers 1.5 to 2× the wear resistance of a conventional O-ring chain, for a longer service life and fewer replacements.
• High Tensile Strength: Rated at 8,430 lbs. average tensile strength and suited for engines up to 750cc.
• Anti-Kink Design: Extended riveted bushing with anti-kink construction, solid rollers, and shot-peened components for smooth, reliable operation.
• Gold Clip-Style Master Link Included: Comes with one gold clip-type (press-fit-clip) master link for easy installation and chain maintenance.
• Made in Japan: Manufactured in Kaga, Ishikawa prefecture, Japan by skilled technicians to D.I.D's exacting quality standards.
• Maintenance Friendly: Chain cleaning every 300 miles is recommended; use X-Ring safe cleaners and lubricants to preserve the seals.
