Motor cover is an common metal parts of motorcycle. It’s mainly used to cover and protect engine component from being dirty or damaged. This part is made from lightweight aluminum casting processes roughly, and reworked by CNC machine to obtain precision features or shapes.
Since it cover must be connected with interior motor and other movement components accurately, so it requires the casting piece has very precision dimension in distance and roundness. All of critical dimensions must be 100% inspected by CMM before shipment. We perform SPC report every two hours while mass production.
