The engine is based upon the Subaru EA 81 automotive engine. It is a four-cylinder four-stroke, 1,800 cc (109.8 cu in), liquid-cooled, gasoline engine design, with a belt-type reduction drive with a reduction ratio of 2.2:1. It employs electronic ignition and produces 100 hp (75 kW) at 5400 rpm.[1]
