MASS CENTRALISATION

In terms of physics, the centre of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where, if a force is applied, causes it to move in the direction of the force without rotation. The distribution of mass is balanced around the centre of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates. In a motorcycle, the centre of mass is positioned to be below the rider. Keeping the mass central and as low as possible to the ground reduces the centre of gravity and improves handling. Most manufacturers try and contain as much weight as possible towards the central area around the engine’s crankcase.
