The Dinka Enduro is one of the vehicles at Jason's safehouse in the Ultimate Edition, finished in a shade that points to army green. The Crest kayak sits beside it.
The Ultimate entry is called Jason's Safehouse Vehicles and reads: 'Switch gears and soak up the sun in an Army fatigue-tinged Dinka Enduro motorcycle or Crest Kayak.' The army color nods to Jason's time in the Army. The Enduro is a dual-sport bike that also appeared in GTA V, and dirt-bike races were shown in the Extended Look.
