Welcome to the forums... the 250EX and the 250X are the same they just dropped the "E". Now from 1987-1992 they built a 250X which was entirely different,and from 1993 -up the 300EX took the 250X place. In 2006 they added a sport clutch option to the 250EX allowing biginner riders the experience of using a clutch but with no stall. It was still a footshift but you could use it either way.
