DID Chain – 525VX122 VX-Series X-Ring – BLACK

D.I.D has merged their Professional O-Ring V Series and their top selling Premium X-Ring® VM Series into “ONE” New Pro-Street X-Ring® VX Series. Created from the severe demands of today’s top World Superbikes, D.I.D is proud to introduce this New high performance VX Series.

• In developing this new series, D.I.D focused on improving “Rigidity”.
• Traditionally, “Tensile Strength” has been used to indicate the overall strength of a chain. But Tensile Strength is only a laboratory static measurement of a chain’s “breaking point”. Rigidity, on the other hand, is the ability of a chain to withstand forces that occur in a rider’s real world experience.
• Increased rigidity means better power transfer from the engine to the ground and greater resistance to stretching under load. This translates into smooth handling and quicker response time.
• To maximize performance, D.I.D’s race proven X-Ring® design delivers overall improved performance that meets the demands of today’s high-performance machines. The VX Series is the ultimate in performance and durability, and are a perfect match for your dual sport, sport bike or sport touring bike.

The 525 VX Series chain is suitable up to a maximum engine size of 900cc.

DID’s VX Chain uses patented X-ring seals. Like O-rings, X-rings function to seal in lubrication and keep dirt out.

Where the cross section of an O-ring is circular, the cross section of an X-ring is ‘X’ or cross shaped. This gives the seal additional contact points compared to the O ring, offering superior sealing and protection against dirt and grit getting stuck under the seal.

In addition, when under pressure an O-ring becomes squashed and causes friction. An X-ring, when under pressure, diverts this pressure by twisting instead. Therefore, an X-ring decreases friction between side plates. As a result, it reduces power loss by 50% of any other type O-ring chain.

Half the Power Loss (Compared with Normal O-Ring)

• D.I.D’s PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed.
• In contrast, normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction.
• The twisting action of the X-Ring disperses the pressure. This action minimises power loss.

DID’s X-rings have 40% greater Wear Resistance (Compared with Normal O-Ring)

• The X-Ring’s four contact points greatly increase its sealing performance. Thus, it keeps the dirt out and the lubrication in much better than any other O-Ring.
• X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain, this means more resistance to stretching, bowing and warping and smoother handling.
• With the proper maintenance an X-ring chain will last longer than any O-ring or unsealed chain.
