The DID 520 ERVT Narrow Enduro Racing Narrow X-Ring Chain gives you the wear resistanace of a sealed X-Ring chain in a package that is no wider than most non-sealed chains.

D.I.D Motocross Chains

If your bike has slim clearances designed for traditional, non-sealed drive chains, DID's ERVT is a great choice for getting the extended durability of their X-Ring chain in a narrow package. The ERVT uses DID's patented X-Ring design to hold lubricant inside the chain assembly and reduce friction points that occur in every link. This makes the ERVT specifically geared for the harshness of off-road riding with 1.5 to 2 times the lifespan and half the power loss of competing O-ring and modified O-ring designs.

The ERVT chain is highly robust with an ultimate tensile strength of 37.54Kn (8,440 lbf) and is recommended for any bike 500cc or under. So if your bike fits narrow, non-o-ring chains but you want the low maintenance overhead of a sealed chain, you will welcome DID 520 ERVT Narrow Motocross Racing X-Ring Chain.

DID ERVT Series Narrow X Ring Chain features:

• Sealed ring chain with narrow body width
• Same width as non-o-ring chains
• More durability with less adjusting and lubrication
• Half the power loss of other O-ring and modified O-ring designs
• 1.5 to 2 times longer wear life than other O-ring and modified O-ring designs
• Includes master link
• 37.54Kn (8,440 pounds) tensile strength
• 125 - 500cc displacement recommended
• Patented X-Ring® design

Priced per link, full chain orders include a hollow rivet link.  Solid rivet and press-together clip links are available as options.  If you are unsure of the number of links needed, try out chain length calculator tool on the "Workin' on the Chain Gang" intro page.

Please Note: Chains are priced per link. If the quantity column shows 1, enter the number of links instead.
