Available Materials for Premium Motorcycle Parts
CNC machining can be applied to a wide variety of high-performance materials, bringing endless possibilities to motorcycle parts processing. These include various grades of aluminum alloys, titanium alloys, stainless steel, and some composite materials. Our team of dedicated engineers can help you select the most suitable material based on your specific motorcycle part requirements (such as strength, weight, heat resistance, and corrosion resistance) and budget, providing you with the most cost-effective solution.


Available in Diverse Types of CNC Machining
Our factory is equipped with 50+ multi-functional CNC machining centers, meeting your complex processing needs of various motorcycle accessories.
- CNC milling service: Capable of processing various contours such as planes, curved surfaces, cavities, holes, threads, etc.
- CNC turning service: Good at processing axisymmetric parts, turning and milling composite processing greatly improves processing efficiency.
- CNC grinding service: Including external cylindrical grinding, internal cylindrical grinding, surface grinding, and tool grinding, etc., to achieve the highest dimensional accuracy and best surface finish for your motorcycle parts
- CNC drilling service: Efficiently complete the processing of holes, fasteners, and other parts required for motorcycle assembly.
CNC motorcycle parts are precisely processed by CNC machine tools. Due to their excellent craftsmanship and performance, they are very popular in the field of motorcycle modification and upgrading.
- High Precision—The CNC machining process is controlled by a computer program. Automated production reduces errors caused by manual operation and can achieve tolerance control of +/-0.005 – 0.01 mm and customizable surface roughness of Ra0.2 – Ra3.2.
- Consistent Quality—CNC machining makes every part you get almost identical in the mass production of motorcycle parts, making it the first choice for consistent, high-quality motorcycle parts.
- Lightweight—CNC machining is suitable for high-strength and lightweight metal materials such as titanium alloy, aluminum alloy, and low-carbon steel. In addition, through precise CAD design and program settings in the early stage, CNC machining can accurately hollow out the material, maximize the utilization of the material, and ensure the strength and lightness of your motorcycle parts at the same time.
First, CNC racing motorcycle parts are usually made of advanced materials such as carbon fiber and lightweight alloys to reduce weight and increase strength. Ordinary motorcycle parts often choose more cost-effective materials, namely, general steel and aluminum, to meet most basic riding needs.
Lightweighting is particularly crucial for components such as wheels and brakes, which are essential to racing performance. Racing motorcycle brakes utilize high-friction materials and specialized calipers to achieve superior stopping power.
In addition, the racing suspension system is usually designed for precise handling at high speed and is adjustable.
Our rigorous quality control procedures include: Raw material inspection (material verification, machining accuracy verification, and process document review); In-process inspection (first-article inspection, patrol inspection, and final-article inspection); Finished product inspection (full dimensional measurement, appearance and surface quality assessment, and packaging and labeling inspection).
