The Mach 7-X took the classic Mach 7-7 to a new level by giving it a major upgrade: X-Flex Core. The X-Flex Core was a rubber mesh system designed by Morey to provide superior projection, flex, and response properties throughout the entire board. The first generation Mach 7-X retained the classic look of the yellow deck, black rails, and orange bottom that faithful Mach 7-7 fans had come to know and love.
