Dec 22, 2020· This type of engine is little less fuel efficient than the single cylinder engine. But that is really not so significant in modern designed double cylinder engines. Double cylinder engines are heavier than the single cylinder engine motorcycle. Hence for commuters and hardcore off road bikes this type of engine is not best option.
running, more fuel efficient performance. Because of the increased volumetric efficiency, an OHV engine will produce more torque per unit of displacement than a side valve engine. The life of an OHV engine is also longer because the design allows greater airflow around the cylinder head keeping the engine cooler and reducing oil consumption.
