The TR250i is powered by a 249cc, 2-Stroke, single cylinder engine. With a cylinder bore of 72.5 in and stroke of 60 in, its motor is oversquare, meaning that the cylinder bore (width) is greater than the stroke (length). This makes the engine more powerful than one of similar displacement with a smaller bore. The engine is supported by electronic fuel injection which ensures smooth and timely fuel delivery.
