Legendary YZ250 249cc liquid-cooled reed-valve-inducted two-stroke engine – focused on making a wide, controllable power character ideal for off road racing.

YZ250 based frame

A carefully engineered, advanced aluminium frame and swingarm give the YZ250X the famous handling proven by the championship winning YZ250 motocross machine on tracks around the world. Tips the scales at just 104kg with all fluids – which makes it lighter than a four-stroke.
