A motorcycle frame includes the head tube that holds the front fork and allows it to pivot. Some motorcycles include the engine as a load-bearing, stressed member. The rear suspension is an integral component in the design. Traditionally frames have been steel, but titanium, aluminium, magnesium, and carbon-fibre, along with composites of these materials, have been used. Because of different motorcycles' varying needs of cost, complexity, weight distribution, stiffness, power output and speed, there is no single ideal frame design.

Famous quotes containing the words motorcycle and/or frame:
“Today, only a fool would offer herself as the singular role model for the Good Mother. Most of us know not to tempt the fates. The moment I felt sure I had everything under control would invariably be the moment right before the principal called to report that one of my sons had just driven somebody’s motorcycle through the high school gymnasium.”
—Mary Kay Blakely (20th century)
“With its frame of shaking curls all in disarray,
earrings swinging,
make-up smudged by beads of sweat,
eyes languid at the end of lovemaking,
may the face of the slim girl
who’s riding on top of you
protect you long.
What’s the use
of Vi.s».n»u, iva, Skanda,
and all those other gods?”
—Amaru (c. seventh century A.D.)
