A fuel injection type two-cycle engine for motorcycles. A fuel injection valve for injecting fuel into an air intake passageway at a predetermined timing is disposed on the upstream side of a reed valve in the air intake passageway communicating with an interior of the engine via the reed valve, with the injection port thereof directed towards the reed valve. An air intake pipe forming the air intake passageway extends nearly in the vertical direction from the upper surface of a crank case at an middle position between a crank shaft extending in the widthwise direction of the vehicle body and a transmission shaft separated from the crank shaft in the back and forth direction and extending in the widthwise direction of the vehicle body, and a fuel injection valve protrudes from this air intake pipe in the back and forth direction. The air intake pipe and the fuel injection valve are positioned between left and right vehicle body frame members above the engine, and a partition plate is provided between the vehicle body frame members and the engine main body.
