produces only one power stroke every two crankshaft revolutions.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    That makes flywheel inertia especially important.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    The OKMO 916 uses \u003cstrong\u003etwin stainless-steel flywheels\u003c\/strong\u003e, adding rotational inertia to help carry the crankshaft through the non-power strokes\n    and allowing the
