Brass Finish Care
- Natural Aging: Brass develops rich patina over time—this is normal and adds vintage character

- Polishing: Apply brass polish 1-2 times yearly if you prefer bright finish
- Protection: Store indoors when possible to slow patina development
British Heritage Styling
The brass finish evokes classic British motorcycle aesthetics from the 1960s-70s golden era, when polished brass badges and components were hallmarks of premium engineering. Paired with Union Jack iconography, these covers celebrate Triumph’s Hinckley heritage in subtle yet distinctive fashion.
