==Design and development== The engine is a development of the [[Suzuki G engine#G10|Suzuki G10]] [[automotive engine]]. It is a three-cylinder [[Inline engine (aviation)|in-line]] [[four-stroke]], liquid-cooled, gasoline engine design, with a custom-designed belt-type [[reduction drive]] with reduction ratio of 2.11:1. It employs [[electronic ignition]] and produces {{convert|62|hp|kW|0|abbr=on}} at 5700 rpm.<ref name="WDLA11"/> <!-- ==Operational history== --> <!-- ==Variants== -->
