At DMG Motorsports, we present the D.I.D Super 420NZ3-120 Non O-Ring Chain (420NZ3X120RB) — a premium 420-pitch drive chain from the DAI-Hard (DHA) Series, engineered for riders who demand strength and reliability without the extra drag of a sealed chain. This 120-link, non-sealed chain is purpose-built as a high-performance upgrade over stock chains, delivering the low-friction feel racers want combined with genuine D.I.D durability. It's a favorite upgrade for the Honda Grom and other small-displacement bikes, as well as off-road and mini-moto applications that call for a lightweight, low-friction 420 chain that won't stretch or wear out prematurely.

Features:

• 420 pitch, non-sealed (non O-ring) chain with 120 links, part number 420NZ3X120RB
• DAI-Hard (DHA) pin treatment forms a hard chromium-carbide layer on the pin surface for far better wear resistance than other chains
• Up to 19% higher tensile strength along with increased anti-oxidation performance
• Solid bushings and quad-riveted (quad-stake) pins for outstanding strength and long chain life
• Thicker side plates than standard 420 chains, adding extra strength for spirited riding and racing use
• Rated tensile strength of 4,930 lbs (21.9 kN), suitable for machines up to roughly 150cc
• Lightweight, low-friction design intended for racing and performance riders seeking minimal drivetrain drag
• Ideal replacement/upgrade chain for the Honda Grom and similar small-bore street and off-road motorcycles
• Comes with a clip-style connecting link for straightforward installation
