GTA 6's quad bike duties fall to the Dinka Verus, spotted in official screenshots. It is modeled on Polaris Sportsman ATVs and first appeared in GTA Online. At a datamined 750 kg with all-wheel drive and five gears, expect it to shrug off terrain that would strand most cars, while offering the crash protection of a lawn chair.
Nothing is confirmed about getting a Verus. Quads in past games showed up in rural and off-road areas as finds, and were also sold cheaply online, so both routes are plausible for GTA 6's swamps and backroads. Expectation only at this stage.
It was confirmed through official screenshots.
