D.I.D’s 415ERZ is designed for the New Moto3 regulations that require a higher performance chain. Thanks to D.I.D’s exclusive SDH pin treatment, the 415ERZ fights against elongation and stretching.

High Rigidity:

• 'RIGIDITY' is D.I.D's Original Concept born from years of experiences in MotoGP development
• Lower Rigidity = Pins flex robs horsepower. Higher Rigidity = Pins resist flexing reducing power loss
• Quicker response
• Reduced power loss
• Smoother handling

SDH Pin - Extreme Impact Pin Strength:

• SDH pin treatment creates an extremely hard Chromium Carbide Layer on the pin's surface. But at the same time, the inner core is maintained soft to absorb shock loads of extreme jumps, etc.

Solid Bush - Cold-Formed High-Precision Bushing:

• Solid Bushing chains have a high wear-resistance. The cold-formed solid bushings have a smooth seamless surface with complete roundness.
• Solid bushing = longer chain life
