"You should buy this Rear Shock Linkage 154mm hole centre to hole centre"

The rear shock linkage is a component of a motorcycle's rear suspension system that connects the rear shock absorber to the swingarm and frame. It typically consists of a series of levers, arms, and pivot points designed to transfer forces and adjust the suspension’s behavior. The linkage helps to control the rear suspension's movement, providing smoother ride quality and better handling by optimizing the shock absorber's performance.
