Abstract
A motorcycle frame includes hollow left and right frame members that define a fuel-containing volume. Left-center, right-center, left-rear, and right-rear engine supports each depend from a corresponding left and right frame member. Each engine support includes a first portion that is coupled to the frame member and a second portion that is coupled to the engine. Each engine support also includes a stress riser defined between the first and second portions. The stress riser is configured to cause the first and second portions to separate from one another in response to application of sufficient force to the engine or second portion. By causing the first and second portions of the engine mount to separate in a predetermined way, the frame members and the fuel-containing volume are left intact.
