D.I.D. Non-Sealed Racing Chain

The D.I.D Non-Sealed Racing Chain (420NZ3 series) is a premium 420-pitch racing chain. It is built for mini motocross, pit bikes and other lightweight, small-displacement race machines. D.I.D developed this non-O-ring, non-sealed motorcycle drive chain for riders who want low weight and low friction on the track. It also suits smaller bikes such as the Honda Grom.

Key Features:

• Non-sealed design: No O-rings or X-rings, which keeps friction low and weight down for racing use.
• Solid bushings: Add strength and durability under high-revving race loads.
• Heat-treated pins: D.I.D's special pin treatment improves hardness, wear resistance and impact resistance.
• Lightweight race construction: Designed for smooth power delivery with minimal rotating mass.
• Clip-type connecting link: Makes installation and routine maintenance simple.
• Made in Japan by D.I.D, a long-established motorcycle chain manufacturer.

Because this chain is non-sealed, it needs regular cleaning and lubrication to get the best service life. Clean and lube it often, especially after racing in dusty or wet conditions.
