Description

ABSTRACT:
A motorcycle arrangement including a conventional head pipe with rectangular main pipe and down pipe elements rigidly attached to an engine to define triangular truss structures to create a rigid frame. Brackets cooperate with the ends of the main pipes to affix same relative to the engine. The brackets may be employed as part of a subassembly including the rear suspension. The rear swing arm and the cushion member are both attached to the bracket structure and may be removed from the frame together. Other components may be most advantageously coupled with a bracket structure to avoid excessive use of the frame itself for such mounting functions. Such items as footpegs, gear shift pedals and retractable stands may be fixed to side brakcets for easy preassembly and reduced complexity.
