"You should buy this Oil tank"

An oil tank (reservoir) on a motorcycle is a container used to hold and store oil, typically for the engine, transmission, or other systems like hydraulic clutch or suspension. It ensures a steady supply of oil to the engine or other components, helping with lubrication and cooling. The oil tank is designed to be durable, often made of metal or high-quality plastic, and is located in a convenient area for easy access and maintenance.
