D.I.D. ZVM-X Drive chain is their top of the line high quality chain. An X-Ring Drive chain with Direct Energy Transfer, SDH Pin for extreme impact Pin strength, Solid Bush Cold-formed High-precision Bushing. 

This chain is an X-Ring sealed chain. That has rubber seals fitted between the links. These seal in the grease and keep the dirt out, reducing the wear on the chain and extending its life. The X-ring chain is the newest development where the rubber O-ring is replaced with an X shaped seal. As the X-Ring has a smaller surface area than the O-ring it reduces friction minimising the loss of power in the drive chain while maintaining the benefits of increased lubrication and reduced wear.

X-RING
D.I.D’s Patented X-Ring is superior to others. Half the power loss compared with a normal O-Ring chain. D.I.D’s Patented X-Ring construction reduces friction by twisting between the side plate instead of being squashed. The twisting action of the X-Ring disperses the pressure and minimizes power loss. The X-Ring’s four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring type seal.

DIRECT ENERGY TRANSFER
“DIRECT” is D.I.D. Original Concept born from years of experiences in MotoGP Development to increase the chain’s rigidity. Rigidity in a chain means resistance to chain deformation and elongation. “DIRECT” gives you amazing throttle response by preventing pins form being flexed during acceleration and deceleration. Direct Energy Transfer! with Direct Energy Transfer, lets you feel every twist of the throttle with amazing acceleration response. This is due to our state-of-the-art technology to increase the rigidity in a chain

SDH PIN
SDH pin treatment creates extremely hard Chromiumcarbide layer on the pin surface. But at the same time the inner core is maintained soft to absorb shock load of high jump giving Extreme Impact Pin Strength.

SOLID BUSH
Cold-Formed High-Precision bushing, solid bushing chains have a high wear-resistance. The coldformed solid bushings have a smooth seamless surface with complete roundness.
