Abstract
A motorcycle frame including a base portion and a removable portion that both bear operating loads of the motorcycle. The removable portion and base portion are fastened together at a joint comprising a first end cap 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.
