The DID ERVT developed as an enduro racing chain and meats almost the performance of the ERV3. It is a little bit lighter and therefor it is a very good racing chain for SSP, which often have no better OEM chains.
By less to accelerate masses and less in turning to accelerate masses, and easier run you will have a relevant performance advantage. The lower moment of inertia (by mass and turning masses) also provides a better handling.
Because of lower tensile strength (e.g. compared to DID 525 ZVMX) it is recommended not to use this chain with SBKs (1000ccm) for clutch-wheelies at two person rides. You also should change the chain, if there are obvious signs of wear. In addition it is recommended not to use the optional clip lock with SBKs.
