A Motorcycle Engine Mount having Improved Stiffness. The device is a bolt-in replacement for the Original Equipment Manufacturer engine mounts for FXD_ series Harley Davidson motorcycles. The device has a single-piece, hardened steel outer frame, and a interstitial formed from urethane (rather than rubber) having a durometer reading of approximately 80. Unlike the device of the Parent Application, the urethane interstitial element is not bonded to the outer frame element so that the urethane interstitial element can be slid out of the outer frame and replaced, if desired. The interstitial element protrudes from the outer frame, and does not reach the full depth of the outer frame depth.
