DID is proud to present its 520 ERT3 chain:

With uncompromisable strength, the 520ERT3 has 25% greater anti-shock performance and a 5% higher tensile strength that the previous generation chain without any added weight.

The new 520ERT3 chain is chosen by AMA factory teams, such as Honda, Yamaha, Kawasaki, Suzuki, and KTM.

• The ERT3 chain is used by the best supercross and motocross factory teams
• D.I.D's exclusive SDH pin treatment is the secret behind the excellent performance and is ideal for use in muddy / sandy conditions.
• The revolutionary SDH treatment forms an extremely hard chromium carbide layer on the pin's surface, while maintaining a soft inner core
• SDH-treated pins have very high impact strength while maintaining outstanding shock absorption.
• This treatment creates a chain with superior anti-oxidation properties and wear resistance, for top performance and protection from foreign materials.
