D.I.D 520 ERV3 X-Ring Chain:
The D.I.D ERV3 X-ring chain is the ultimate high-performance, lightweight, low-friction race chain available and is used extensively by many off-road race teams. The ERV3 X-ring chain utilizes D.I.D's patented X-ring technology which reduces friction by 50% over standard O-ring chains for minimized power loss. The pins on the ERV3 X-ring chain have been put through a patented heat-treatment process to produce a pin that is 1.5 times harder than conventional pins. The result is a chain that is significantly stronger and offers better wear resistance than many other chains on the market. D.I.D ERV3 X-ring chains feature a gold-plated finish that resists rust and adds a little style to your motorcycle or ATV.
D.I.D 520 VX2 X-Ring Chain:
D.I.D's Pro-Street X-Ring® VX Series Chains are high quality X-Ring® chains with superior strength to withstand the horsepower of today's dual sports and trials bikes. The VX Series uses D.I.D's patented low friction X-Ring® for maximum performance.
Note for installing X-ring chains: As X-ring chains are wider than standard roller chains, when fitting an X-ring chain to a motorcycle that was fitted with a non O-ring chain as original equipment, it is essential to check that there is proper clearance of the engine cases near the countershaft sprocket and any other places of close contact. Failure to do so could result in damage to the chain and motorcycle and could ultimately cause the chain to fail.
