This invention is an apparatus for increasing motorcycle riding comfort. It is particularly designed for use with Harley Davidson SofTail motorcycles. The engine and transmission are mounted on a main engine mount of the present invention which is attached to a pair of main engine vibration isolators which are bolted to an engine base plate. The engine base plate is welded to the bottom of the frame. The main engine vibration isolators allow longitudinal rocking of the engine and transmission while minimizing energy transfer to the frame. A front engine vibration isolator is affixed between a front engine anchor bracket, which is bolted to the engine, and a front engine mount bracket, which is welded to the front of the frame. This provides additional support to the engine while allowing the engine to rock with minimal energy transfer to the frame. A front hyme and a top hyme provide for obtaining and maintaining proper alinement of the engine and transmission. A pair of rear hymes prevent longitudinal displacement of the engine and transmission. The installation of the engine vibration reducing components of the present invention requires the removal of the two stock shocks which are concealed beneath the engine and transmission. An air suspension system is used to replace the stock shock absorbers. An air bag is mounted between an air bag mount bracket, which is attached to the top rear of the frame, and an air bag compression plate, which is attached to the top front of the rear axle swing arm. Two oil bag brackets with vibration isolation replace the stock oil bag mount plate and two swing arm stops prevent excessive upward rotation of the swing arm. The oil bag brackets and the swing arm stops are bolted to the top rear frame beam.
