Diasil Cylinder
(Die-casting Aluminum–Silicon Cylinder)

Yamaha Motor was the first manufacturer in the world to develop a cylinder with the DiASil. It used the controlled filling (CF) die-casting technology to make an aluminum alloy containing higher silicon possible for using, which had been considered very difficult for the castings. The manufacturing technique makes mass-production to be realized for all-aluminum cylinders that had excellent sliding characteristics without a sleeve, and increases wear resistance, production efficiency, obtains good recyclability.
