The Explorer 280 is powered by a 248cc, 2-Stroke, liquid-cooled, single cylinder engine. With a cylinder bore of 2.85 in and stroke of 2.36 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. Electronic ignition makes starting your bike a breeze and ensures a consistent throttle response.
