420 Motorcycle Chain

Our 420 motorcycle drive chain is a lightweight, cost-effective transmission part specially designed for small-displacement motorcycles, pit bikes and electric motorcycles, combining durability, smooth performance and high cost performance as its core advantages.

Crafted with premium carbon alloy steel, this 420 chain features integrated stamping chain plates and heat-treated pins. The overall structure improves hardness and tensile strength, effectively resisting stretching, deformation and rust. Polished inner and outer rollers greatly reduce friction between sprockets and chains. It cuts down driving noise, ensures flexible transmission and delivers smoother throttle response during acceleration.

Featuring compact 420 standard size, it boasts excellent universal compatibility. It fits most 50cc to 125cc street bikes, off-road pit bikes, mini motorcycles and lightweight electric vehicles, requiring no extra modification for installation. The pre-lubricated factory design saves assembly time and offers basic wear resistance to extend service life.

Besides, we optimize gap tolerance to prevent chain derailment during high-speed riding. Anti-corrosion surface coating adapts to rainy and humid daily riding conditions, slowing down oxidation. Lightweight body lessens drivetrain burden to save fuel consumption. Reliable quality, easy installation and low maintenance cost make our 420 motorcycle chain an ideal replacement part for daily riders.
