Final drive power transmission on motorcycles is currently dominated by three big concepts: chain drives, belt drives and shaft drives. Both belt and shaft drives have some major disadvantages so chain drive is still the most popular power transmission system fitted on motorcycles today. Chains are lightweight, robust, easy to install and adjust, and highly efficient.
However, just like any other form of transmission, they do require care and maintenance for best results. The good news is that chain maintenance is easy and a properly cared for chain can last a long time. The bad news is that a neglected chain can become inefficient very quickly and fail early, resulting in a costly replacement bill. Basic maintenance like chain and belt tension, and lubrication.
