- Custom Touches: Includes new plastics from Polisport and semi-custom graphics from Decal MX.
Technical Components:

- Performance Parts: Exhaust upgrades like the FMF Fatty Pipe and Shorty Silencer provide enhanced output.
- Braking System: Upgraded hydraulic brake lines and refurbished calipers ensure responsive handling.
Key Suppliers:
