Summary: | PROBLEM TO BE SOLVED: To provide a new motorcycle frame for satisfying a structural requirement, and simultaneously for facilitating installation and removal of an engine while simplifying a rearrangement processing of a predetermined motorcycle component. SOLUTION: This frame includes a base portion and a removable portion that both bear operating loads of the motorcycle and can be fastened by a joint. The joint comprises a first end cap (EC) having a protrusion, a second end cap having a recess, and a fastener having a fastener axis and extending through the first and second end caps. The protrusion and the recess are characterized by angled walls oriented at an acute angle with respect to the fastener axis. The angled wall engagement of the end caps ensures that substantially all shear loads in the joint are born by the end caps and not by the fastener. The motorcycle footpeg position can be changed by replacing the removable portion with a second removable portion having footpeg mounting structure at a different location than the removable portion.
