| We've all seen cars with bad shocks, pogoing their way down the freeway. A wheel hits a bump and compresses, then rebounds, then re-rebounds, maybe as many as three or four times. This is oscillation and it can make a car (or a bike) nearly impossible to control. | We've all seen cars with bad shocks, pogoing their way down the freeway.

| - | This is where shocks (or, more correctly, spring dampers) come in. The damper is partially filled with oil which is forced through small orifices when the fork (or rear shock) compresses and rebounds. The friction of the oil through these passages retards the movement of the suspension, taking energy from the spring and transferring it to the oil as heat. | + | This is where shocks (or, more correctly, spring dampers) come in.

| You can get a feel for good damping by bouncing on the seat of a well-set-up Sportbike, motocrosser or racebike. Bounce on the seat and stand up immediately - you'll feel the bike rise quickly to almost full height, then slow down the last bit of travel. Often you can feel the same thing when compressing the forks. That's damping in action. | You can get a feel for good damping by bouncing on the seat of a well-set-up Sportbike, motocrosser or racebike.
