At DMG Motorsports, we present the D.I.D 520ATV2 ATV X-Ring Sealed Chain — a purpose-built, competition-grade drive chain engineered exclusively for the punishing demands of quad racing. Part of D.I.D's Exclusive Racing Series, this ATV-specific X-Ring sealed chain delivers exceptional strength and outstanding chain life in a gold finish that looks as tough as it performs. Manufactured in Japan by skilled technicians to exacting standards, the 520ATV2 is trusted by top ATVMX riders and is the go-to choice for anyone serious about getting the most from their machine. Available in multiple link lengths — 96L, 100L, 104L, 120L, and 130L — so you can find the perfect fit for your ride.

Features:

• ATV-Exclusive Racing Series Design: Engineered specifically for the severe demands of ATV racing, delivering superior performance over standard motorcycle chains.
• 7% Lighter, 10% Stronger, 8% Longer Wear Life: Outperforms comparable chains across all three key performance metrics.
• X-Ring Sealing Technology: D.I.D's patented X-ring reduces friction by twisting between side plates rather than being compressed, providing four contact points for maximum sealing — keeping dirt out and lubrication in far better than standard O-ring chains.
• Half the Power Loss of O-Ring Chains: The X-ring design delivers 1.5 to 2× the wear resistance of a conventional O-ring chain with significantly less friction.
• Thicker Reinforced Side Plates: Provides extra strength and improved heat dissipation — ideal for hard-charging, throttle-pinned riding.
• Special Steel Alloy Construction: Minimizes heat cracking in cold weather caused by the severe heating and cooling cycles experienced during competition.
• Average Tensile Strength of 8,430 lbs: Built to handle high-impact loads with confidence across all terrain.
• Rated Up to 750cc: Suitable for ATVs with engine displacements from 250cc up to 750cc.
• Wear Life Index: 3,250: Outstanding durability for extended service intervals on and off the track.
• Gold-Plated Outer Links: Striking gold finish adds a premium look while helping with corrosion resistance.
• Clip-Style Master Link Included: Everything you need for installation right in the box.
• Weight: Just 3.42 lbs per 100 links for a lightweight yet powerful drivetrain.
• Made in Japan: Manufactured by D.I.D in Kaga, Ishikawa, Japan — a trusted OEM supplier for leading Japanese and European motorcycle manufacturers.
• Multiple Length Options: Available in 96L, 100L, 104L, 120L, and 130L to fit a wide range of ATV applications.
