The rear shack system of a motorcycle plays a crucial role in ensuring a smooth and stable ride by managing the forces exerted on the rear suspension. This system typically consists of springs and pumps (often referring to shock absorbers or hydraulic dampers) that work together to absorb shocks from the road, maintain traction, and provide comfort to the rider. Here’s an in-depth overview of how these components function and contribute to the overall performance of a motorcycle’s rear suspension.
