An off-road vehicle includes a frame and four wheels that support the
frame. An engine powers the wheels. The engine is mounted on the frame.
The frame includes multiple frame members that surround the engine. One
of the frame members disposed behind the engine is detachably affixed to
the rest of the frame members. The frame members are divided into first
and second groups. The first and second groups are offset fore to aft
relative to each other and overlap with each other in a rear section of
the first group and in a front section of the second group. The rear
section of the first group defines a bent portion coupled with the second
group. The front section of the second group defines a bent portion
coupled with the first group.
