Anodizing is a favored finishing option for aluminum components. It forms a tough, scratch and corrosion-resistant layer on the aluminum. Besides, anodizing can be done in black, blue, or red, which can be used to personalize parts to suit the style of your bike. This finish is common on CNC-machined motorcycle parts like levers, foot pegs, and engine covers.

  • Powder Coating

This is a method of applying a dry powder, which is baked on the part to create a tough and colorful finish. It is a very durable finish that also offers protection from chips and rust. This method is frequently used on aluminum and steel, which makes it very common for various motorcycle parts.

  • Polishing

Smooth and shiny finishes are good for parts made of chrome or stainless steel. With parts that are chrome or ss, a smooth, shiny finish can be applied. Polished finishes are common on custom parts where appearance matters as much as function. 

  • Plating

This is a method that covers parts with thin layers of metals, including chrome, nickel, or zinc. It is good for protection against rust while also offering a bright and shiny appearance. 

  • Painting

Some parts of CNC motorcycles are color-treated after being machined. Color-treated CNC parts are not only cosmetically appealing but also guard the underlying metal.
