## The parts

Key components of the Two Stroke motorcycle were made this way: fuel tank cover components, cable retainers and chain guides. Integrating 3D printing with industrial, automated post-processing gave Langen 3D-printed motorcycle parts that meet its design standards and deliver long-term performance on the road.[1]

## What vapor smoothing delivered

- Smooth, sealed surfaces resistant to fuel, oil, and water
- Premium aesthetics that reflect their brand identity
- Improved mechanical durability for real-world riding conditions
- Consistent quality suitable for custom or low-volume production[1]

Result

Smooth, sealed surfaces resistant to fuel, oil, and water[1]
