How a motorcycle transmission works

By replacing the traditional gear set with belt drive, the diameters of the driving and driven pulleys are adjusted dynamically via the centrifugal force of the polycentric beads, enabling stepless speed variation. During acceleration, the outward expansion of the polycentric beads pushes the belt to reduce the transmission ratio; when decelerating, the spring returns to its original position, restoring the transmission ratio.
