A motorcycle including a frame having a backbone and engine carrier prevents the need for front support bars. The power plant is secured to the backbone and engine carrier and may be quickly removed. The power plant turns a hydraulic pump that transfers power to a hydraulic motor via hydraulic fluid. A reservoir of hydraulic fluid is preferably contained in the backbone. The hydraulic motor is contained in a swing arm and connects to one side of the rear wheel. The hydraulic motor acts as both a drive unit and a braking unit. Lights may be secured to the engine carrier to provide a better view of the road.
