Abstract
Motorcycles having front and rear swing arm assemblies as the suspension members therefor are employed with lower frame structures incorporating the power unit as a structural element thereof. The lower frame structures are shown to include brackets mounted to the power unit itself, separate loop frame members and an under channel member. Upper frames are shown to be associated with the lower frames. The upper frames do not support the suspension systems but do support motorcycle equipment such a fuel tanks, air cleaners and the like.
