Most motorcycle levers are made of forged aluminum which is formed then polished and coated. Forging is a process that forms metal using extreme amounts of pressure. First a tool is created that is in the shape of the lever to be produced. This tool is usually created from steel and can be used over and over again. Then heated aluminum is forced into that tool or sometimes pressed into the tool using extreme amounts of pressure. Air and excess material are forced from the tool cavity area. Once cooled the tool is opened to reveal the lever in it’s raw form. Then the lever is then drilled, grinded or tumbled to remove any excess material or burrs. After that process is complete the lever is polished to a smooth surface before going to a coating or chroming process.
