D.I.D. 520ATV2100FB Racing Series X-Ring Sealed ATV Chain 100 Links Gold & Black

The D.I.D. 520ATV2 is a Racing Series X-Ring sealed drive chain engineered specifically for the demands of ATV competition. Part of D.I.D.'s exclusive ATV racing lineup, this 100-link chain delivers a winning combination of reduced weight, superior strength, and extended service life compared to standard ATV chains.

D.I.D.'s patented X-ring seal design reduces friction by twisting between the side plates rather than being compressed, dispersing pressure evenly across four contact points. This minimizes power loss while dramatically improving sealing performance — keeping dirt out and lubrication in far more effectively than conventional O-ring chains.

Key Features:

• 7% lighter than comparable ATV chains for improved performance and handling
• 10% stronger tensile strength — rated at 8,430 lbs. for maximum durability
• 8% longer chain life versus similar competitive products
• Thicker reinforced steel side plates provide extra strength for quad racing applications
• Special steel alloy construction resists heat cracking caused by severe heating and cooling cycles during competition
• X-ring technology delivers half the power loss and up to 2x the wear resistance of standard O-ring chains
• 100 links in a striking Gold & Black finish
• Maximum supported engine displacement: 750cc
• Clip-type master link included

D.I.D. recommends cleaning the chain every 300 miles and using only X-ring safe cleaners and lubricants. D.I.D. drive chains are manufactured in Kaga, Ishikawa, Japan, and trusted by top ATVMX competitors worldwide.
