Why Upgrade Your Radiator Guard?
Stock mesh guards offer minimal protection and bland appearance. Billet aluminum upgrades provide triple benefits: superior stone deflection to prevent radiator punctures, enhanced airflow design that maintains optimal cooling efficiency, and custom British styling that transforms functional protection into visual statement.
Maintenance
- Cleaning: Rinse with water after dusty rides to prevent buildup in cutouts
- Inspection: Check mounting bolts every 2,000 miles; retighten if needed
- Winter Care: Remove road salt residue promptly to prevent corrosion
British Craftsmanship
Designed and manufactured in the UK by Motone Customs. Each guard undergoes precision CNC cutting, edge finishing, and multi-stage anodizing to ensure consistent quality and perfect fitment.
