D.I.D. 420X126RB 420 Standard Series Non O-Ring Drive Chain 126 Links

The D.I.D. 420X126RB is a 420 Standard Series non-sealed roller drive chain featuring 126 links. D.I.D. (Daido) is the world's number one motorcycle chain manufacturer, trusted by factory race teams across all major manufacturers and racing series. This chain is engineered for smaller displacement machines originally equipped with non-O-ring chains, including mopeds, scooters, and vintage motorcycles.

Built from special alloy steel with exacting manufacturing tolerances, the 420 Standard delivers reliable power transfer and low friction operation. The chain arrives factory pre-stretched and shot-peened, reducing initial break-in time and helping maintain proper tension right out of the box. A clip-style master link is included for straightforward installation.

Key Features:

• Special alloy steel construction for strength and durability
• Solid rollers with high cylindrical and roundness accuracy
• Quad-staked pin riveting with extended riveted bushing anti-kink design
• Exacting tolerances for low friction and smooth operation
• Factory pre-stretched to minimize initial chain stretch
• Shot-peened components for improved fatigue resistance
• Average tensile strength of 4,200 lbs
• Industry standard wear life index rating of 100
• Includes clip-style master link (connecting link)
• Non-O-ring / non-sealed design — ideal for machines originally equipped with standard chains

Specifications:

• Chain Size: 420
• Links: 126
• Pitch: 1/2 in. (12.7 mm)
• Type: Standard Non-Sealed (Non O-Ring)

Note: As a non-sealed chain, more frequent lubrication and maintenance is required compared to O-ring or X-ring sealed chains. This chain is primarily recommended for off-road and low-horsepower applications.
