CRF300L and CRF300 Rally – DID Chain – 520 VX3-106 VX-Series Heavy Duty X-ring GOLD

• 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. This development is especially beneficial for CRF300L and CRF300 Rally riders looking for a reliable DID Chain. 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”, making it ideal for CRF300L and CRF300 Rally users looking for a robust DID Chain.
• 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 for CRF300L and CRF300 Rally riders using the DID Chain.
• To maximise 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 is a perfect match for your dual sport, sport bike or sport touring bike, including the CRF300L and CRF300 Rally.
• The 520 VX Series chain is suitable up to a maximum engine size of 900cc, providing ample capacity for your CRF300L and CRF300 Rally.

DID’s VX Chain uses patented X-ring seals, making it an exceptional choice for CRF300L and CRF300 Rally riders.

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. This configuration offers superior sealing and protection against dirt and grit getting stuck under the seal, making it perfect for CRF300L and CRF300 Rally enthusiasts using the DID Chain.
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 and 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. 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 and minimises power loss, making it efficient for CRF300L and CRF300 Rally usage with a DID Chain.

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. As a result, 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. Additionally, it ensures smoother handling, especially beneficial for CRF300L and CRF300 Rally riders relying on the DID Chain. With the proper maintenance an X-ring chain will last longer than any O-ring or unsealed chain.
