I am not sure on the adjustable part but the seats in the Maverick are removable and freestanding
EDIT: Adjustable driver seat and tilt steering
The full bolster seats, along with their lumbar and shoulder support, are designed to offer lateral support during aggressive riding and allow easy entry and exit of the machine. The driver’s seat is adjustable fore and aft without the need of tools, making it easily adaptable to a range of drivers and driving styles. The tilt steering wheel also adjusts without the need of tools. The gauge in the Maverick is integrated with the steering column so it will pivot (raise or lower) with the steering wheel for enhanced visibility.
