An improved frame construction for a vehicle such as a motorcycle in which the main tube and down tubes are connected to the head pipe at its lower end so as to afford an increased gas tank capacity. A reinforcement brace in the form of upper and lower braces absorb bending and twisting forces at the connection between the main and down tubes and the head pipe. The connection of the down tube to the reinforcement brace is disconnectable so as to permit removal for servicing of the engine.
