Rigid frame (hardtail)

A rigid frame, often called a hardtail, has no swingarm or rear suspension; the rear wheel is mounted straight to the frame. Bumps are absorbed only by the tyre and, usually, a sprung saddle.

Almost all motorcycles were built this way until the late 1940s and 1950s. Today rigid frames are mainly found on custom choppers and bobbers, where the clean, low look is valued over comfort.

A hardtail is harsh on rough roads and gives less rear grip on bumpy corners. If you want the look with more comfort, a softail-style frame hides the suspension under the bike.
