Description
520ERV7 : DID EXCLUSIVE RACING




MotoGP Spec
The DID 520ERV7 is a chain with very similar characteristics to the chains used in MotoGP.
Lightweight
The pin of the 520ERV7 is grooved to reduce weight without compromising strength.
Features
- Low friction
- Agile and strong
- X-RING Improve fuel efficiency by reducing friction. DID's patented X-ring reduces sliding resistance by 50% compared to genuine O-ring chains, resulting in smoother running and improved fuel efficiency. *The lower the number, the lower the friction = lower fuel consumption and higher responsiveness.
- DIRECT Specifically designed by DID, stemming from experience in MotoGP development.
Faster response, reduced power loss, and improved handling are achieved by focusing on the driver's feel, which is difficult to quantify. To enhance the rigidity of the areas actually used for acceleration and deceleration, we employ meticulous design, material selection, and manufacturing processes for each size, all tailored to the driver's sensibility.

- SOLID BUSH Seamless Bushing This is a solid bushing with high wear resistance, featuring a smooth, round, seamless surface that allows for optimal friction.

- RACING For use in competitions. Exclusive Racing Chain is designed for racing, utilizing advanced technology to achieve strength, lightweight construction, excellent shock resistance, and high performance.
