DE Twincam Performanace Shock Tech 101:

For the most part, the inner workings of motorcycle suspension seem to be shrouded in a great deal of mystery. Although the spring element of the up and down motion is readily obvious, the magic that happens within, and which truly defines the difference between a good and not-so-good suspension, tends to elude most riders. Having a basic understanding of these critical components is not only important, but is ultimately the path to your becoming a better, and certainly more comfortable, rider.

The Basics of Motorcycle Suspension

Motorcycle shocks, as well as the suspension element of forks, can be divided into two basic components: The spring(s), which function by carrying the load, as well as absorbing the impact of bumps and other road imperfections, and a damper, which dissipates the energy created by the springs' compression and resulting extension, usually referred to as rebound.
