Engine mounting structure for motorcycles

摘要

An engine mounting structure for a motorcycle including a plurality of resilient members for connecting the engine to the vehicle body frame. The resilient member located at the position nearest to the rear wheel is given a resilient property being uniform in the vertical and fore-and-aft directions, and remaining resilient members are given a non-uniform resilient property being hard in the vertical direction and flexible in the fore-and-aft direction. With this configuration, even when the rear wheel moves horizontally in the lateral direction, the influence is attenuated while being transferred to the vehicle body frame. When a resilient member being hard in the vertical direction is used, the behavior of the rear wheel such as the vertical swinging motion or lateral turn can immediately be transferred to the vehicle body frame. Therefore, drivability of the motorcycle during high-speed driving is improved.
