A motorcycle top box presents an interesting problem - how to control the motion?

The CSH-63 is a detent hinge which holds things opened or closed - it has a damped version too.

Strong springs allow the S-AT to make a lid feel weightless

A damped hinge like the HG-JH14-50 gives great refinement of movement.

The ultimate in control - a constant torque or friction hinge like the HG-TS is entirely predictable and reliable.
