Abstract
The present invention is directed to an elastomeric sandwich mount for connecting a motorcycle engine to a motorcycle frame. The mount includes an elastomeric member having first and second ends and including a body portion. An interior wall of the elastomeric member defines a cavity therein. The cavity defines a cavity axis extending between the first and second ends. The cavity is axially asymmetric. First and second end plates are secured to the first and second ends of the elastomeric member, respectively. Preferably, the body portion has a substantially cylindrical outer surface.

A method of mounting a motorcycle engine on a motorcycle frame, said method comprising the steps of:
- providing a plurality of substantially identical elastomeric mounts, each of said mounts being responsive to a prescribed static load in a prescribed direction to assume a neutral position;
- selecting first and second locations for connecting the engine and the frame;
- and
- connecting the engine to the frame at the first and the second locations using the mounts;
- wherein the first and second locations are selected and the mounts are oriented such that the mounts are subjected to the prescribed static load in the prescribed direction;
- wherein each of the mounts includes:
