Segment: Trial

The Ossa TR 300i is powered by a 294cc, 2-Stroke, liquid-cooled, single cylinder engine.

With a cylinder bore of 3.11 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.
