Definition of Grade 5 titanium replacement bolts for motorcycle
Grade 5 titanium replacement bolts for motorcycle are fasteners made from titanium alloy through precision machining. They are used to replace the original steel or stainless steel screws on motorcycles to achieve weight reduction, corrosion resistance, and an enhanced visual appeal. They are among the most basic and popular upgrade parts in motorcycle customization, covering a full range of applications from cosmetic components to core load-bearing parts.
why choose titanium alloy?
Significant Weight Reduction: Titanium alloy has a density of only about 4.5 g/cm³, which is approximately 60% that of steel. Replacing all vehicle screws with titanium alloy ones can significantly reduce unsprung mass, making the suspension more responsive and enhancing handling and acceleration. For example, M5-spec titanium alloy screws can reduce weight by up to 50% compared to steel screws.
Outstanding Strength and Durability: The commonly used Gr5 (also known as Grade 64 titanium) titanium alloy has a tensile strength exceeding 900 MPa, rivaling that of high-strength steel. It offers exceptional corrosion resistance, withstanding rain, salt spray, and oil without rusting-effectively making it semi-permanent. Additionally, titanium alloy is non-magnetic and will not interfere with a vehicle's sensitive electronic components.
Unique Aesthetic Value: Titanium alloy screws serve as the finishing touch that enhances the overall refinement of the vehicle. Through the anodizing process, they can be finished in a rich variety of colors-including blue, purple, gold, and iridescent-that are resistant to fading. Their surface texture is smooth and refined, and some products feature specially shaped screw heads, making them highly visually appealing.

- Length: 6 mm to 120 mm (varies; select based on application)
Surface Treatment and Color Processes
1. Anodizing - The Mainstream Process
An oxide film of varying thickness is formed on the titanium surface through electrolysis, and different colors are produced by the interference of light:
Blue: Approximately 80–100 V; the most classic custom color
Gold: Approximately 60–70 V
Purple: Approximately 90–105 V
Green: approx. 110–120 V
Rainbow / Gradient: Segmented voltage control
The oxide film thickness is typically 0.1–0.5 μm, which does not affect dimensional accuracy
2. PVD Coating
Physical vapor deposition (PVD) offers more uniform color and better wear resistance
Common options: Black DLC, Gold TiN, Rose Gold, etc.
Higher cost than anodizing
3. Natural Finish / Sandblasted
Retains the natural color of titanium with a matte texture
Suitable for understated styling modifications
Key Advantages
1. Significant Weight Reduction
For the same specifications, titanium screws are approximately 40%–45% lighter than steel screws.
Replacing all screws on a bike (approximately 100–200 pieces) can reduce weight by 0.5–1.5 kg.
For racing bikes, the reduction in unsprung mass is particularly noticeable (in components such as axles, calipers, and brake rotors).
2. Exceptional Corrosion Resistance
A dense TiO₂ oxide layer naturally forms on the surface of titanium, making it virtually rust-free in atmospheric, rainwater, and seawater/salt fog environments.
It is particularly suitable for harsh conditions such as coastal areas, riding during the rainy season, and off-road muddy terrain.
3. Non-Magnetic Properties
Titanium alloy is a non-magnetic material and will not interfere with onboard electronic devices (This is particularly significant for high-end models with electronic fuel injection)
4. Attractive Appearance and Personalization
Through anodizing, a variety of colors can be achieved, including blue, gold, purple, rainbow, and green
It serves as the "crowning touch" for motorcycle cosmetic modifications
