What is the difference between an O-ring chain and a standard chain?

[NoraAnn]

The differences between an O-ring chain and a standard chain are: 1. Service life: O-ring chains are durable with a long lifespan, but relatively heavier; standard chains are more flexible but have a shorter lifespan than O-ring chains. 2. Structure: O-ring chains have rubber O-rings on both sides of each chain link's joint pin; standard chains lack these O-rings and cannot prevent lubricant leakage or block sand, mud, water, and dust. Chain drive is one of the common transmission methods for motorcycles, with other methods including belt drive and shaft drive. The advantages of chain drive mainly include: 1. Simple and reliable structure with high transmission efficiency; 2. The rotation direction is the same as the vehicle's forward movement, thus not affecting stability during high-speed riding; 3. Flexible power transmission distance; 4. Chain drives can handle higher torque values and are less prone to slipping.
