The Grand Prix spec certified by MotoGP, the drive chain 520ERV7 dedicated to the race is finally released.
The D.I.D 520 ERV7 Racing Chain is an upgrade that will replace the 520ERV3. ERV7 by D.I.D Chain®. D.I.D’s 520ERV7 is the chosen chain of road racing teams in MotoGP, WSBK, MotoAmerica, and used by incredible talents, such as Valentino Rossi, Andrea Dovizioso, and Alex Rins
It has been over a decade since the 520ERV3 was introduced, so the 520ERV7 will see significant upgrades, including stronger inner plates, the 520ERV7 boasts a 3% higher tensile strength, a 13% longer chain life, and less friction due to X-Ring material improvements.
The BEST just got BETTER!
The Grand Prix spec certified by MotoGP, the drive chain 520ERV7 dedicated to the race is finally released. The increased pin diameter improves chain rigidity, resulting in a more direct operation feeling. Also, by optimizing the plate material, uneven elongation of the chain is suppressed, and it exhibits excellent performance that is compatible with vehicles equipped with the latest electronic control. This is a factory spec drive chain that has no compromises in terms of performance, such as dimple processing on the pin tip for weight reduction and friction reduction by reviewing the seal shape.
Tensile Strength Increase – A slight jump from the ERV3, the ERV7 boasts a 3% higher tensile strength due to inner side plates and thicker pins.
Longer Chain Life – Due to increased X-Ring durability, the ERV7 sees a 13% wear resistance increase from the previous ERV3.
Reduced Friction – Because of the X-Ring improvements, the ERV7 will have less friction than the ERV3.
