Frames for all-terrain vehicles

摘要

A frame for an ATV comprises a support module with a central opening defining an engine receiving space. The support module includes a first frame member and a second frame member with at least one cross member extending between the first and second frame members. At least a portion of the support module, which includes one of the frame members and the at least one cross member, consists essentially of a single beam. The single beam may be considered a modular central beam of the frame.
