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.

Motorcycle frame with fuel-storage and break-away engine mounts

A motorcycle including a frame having a top, a bottom, a front, a rear, and a centrally-located longitudinal axis extending through the front and the rear. The longitudinal axis defines a vertical plane. The motorcycle also includes an engine supported by the frame and a radiator coil obliquely mounted to the frame. The radiator coil is spaced apart from the vertical plane and includes a forward end and a rearward end as viewed from above the motorcycle. The forward end defines a first distance measured normal to the vertical plane and the rearward end defines a second distance measured normal to the vertical plane. The first distance is shorter than the second distance.
