The independent rear suspension (IRS) on Yamaha golf carts enhances comfort by absorbing shocks and allowing the rear wheels to move independently, reducing the impact of rough or uneven terrain. This system minimizes jolts and vibrations, providing a smoother ride even on bumpy paths. Combined with an automotive-style front suspension, which improves steering control and stability, Yamaha carts offer a stable and comfortable ride across different surfaces. This dual suspension system is particularly beneficial for commercial and maintenance tasks, where extended use demands comfort.
