The connecting portion of the armrest member is spaced apart from the base member and the upper member and is configured for mounting on the frame of the vehicle.

Abstract: A vehicular frame assembly is provided and includes a pair of control arm support brackets. Each of the control arm support brackets define a pair of recesses. The first control arm support bracket and the second control arm support bracket are substantially identical and are configured to be positioned along a vehicular frame such that one of the pairs of recesses defined by a control arm support bracket receives forward legs of right and left suspension support members and the other of the pairs of recesses defined by the other of the control arm support bracket receives rearward legs of right and left suspension support members. A vehicle is also provided.

Abstract: An all terrain vehicle includes a frame and a control assembly that can be directly or indirectly attached to the frame. The control assembly includes a control knob which can be readily accessible to an operator during operation of the all terrain vehicle.
