D.I.D 520ZVM-X STREET/RACING STANDARD CHAIN

Strong Chain for Superbikes

D.I.D’s ZVM-X Series has greater strength than the VX Series and is designed for heavy weight motorcycles with tremendous torque and horsepower.

Longest Wear Life – The twisting action of the X-Ring® increases its sealing performance and its four contact points minimise power loss.

Quicker Response – The ZVM-X Series’ high rigidity, born from our experience in MotoGP, means greater resistance to stretching under load.

Features:

High Rigidity:

• ‘RIGIDITY’ is D.I.D’s Original Concept born from years of experiences in MotoGP development
• Lower Rigidity = Pins flex robs horsepower. Higher Rigidity = Pins resist flexing reducing power loss
• Quicker response
• Reduced power loss
• Smoother handling

X-Ring:

• D.I.D’s Patented X-Ring is superior to others.
• Half the power loss (compared with normal O-Ring) – 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 minimises power loss.
• X-Ring Chain Endurance Performance (compared with normal O-Ring) – 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.

Solid Bush – Cold-Formed High-Precision Bushing:

• Solid Bushing chains have a high wear-resistance. The cold-formed solid bushings have a smooth seamless surface with complete roundness.
• Solid bushing = longer chain life

This chain is a rivet link chain with 120 links.
