How big is the frame on a Harley Davidson FXRS?
The FXRS’s box-section backbone is massive, making earlier Harley frames look tiny: 0.120-inch-thick stiffeners and gussets reinforce an already monumental (2.5-incti by 3.5-inch, 0.120-inch-thick) box-section bridge. The twin-cradle main section looks conventional except for its robust size: 1.25-inch (32mm) diameter and 0.065 thick.
