Build Your Custom Sur-Ron from the Ground Up
First, a Sur-Ron frame kit allows you to build a custom Light Bee X from scratch or replace a damaged OEM frame . Whether you’re upgrading to a stronger billet chassis, repairing a cracked frame, or assembling a complete custom bike, an aftermarket or OEM replacement frame kit provides the foundation for your build .
The 2025 Light Bee X features a 6000-ton pressure-forged aluminum alloy frame from the factory . However, for high-power builds pushing beyond stock limits, aftermarket billet frames offer significantly greater strength .
Factory OEM vs. Aftermarket Upgrade Frames
| Frame Type | Material | Strength | Best For | Price Range |
|---|---|---|---|---|
| OEM Forged (2025) | Forged aluminum alloy | Good | Stock to moderate builds | Varies (OEM part) |
| OEM Cast (pre-2025) | Cast aluminum | Standard | Light riding | Varies (OEM part) |
| Billet Aftermarket | 6061 CNC billet | Exceptional | High-power builds, racing | 1,500−2,000+ |
The factory cast frame works for light riding but shows limits with harder use . Cracking near stress points, flex under load, and long-term fatigue are common once you add power or ride aggressively .

- Budget – Billet frames cost 1,500−2,000+,whileOEMreplacementframesstartaround770.
- Installation – A frame swap requires transferring all components (motor, battery, suspension, wiring). Plan for several hours of work.
- Color options – Billet frames offer custom powder coating; OEM frames are typically black or raw aluminum.
2025 Light Bee X Factory Frame Upgrade
The 2025 Light Bee X uses a 6000-ton pressure-forged aluminum alloy frame, significantly stronger than the cast frames of previous generations . This factory upgrade improves handling and rigidity while maintaining the Light Bee’s signature lightweight design .
