Fogging visors during cold mornings and rainy rides represent one of the most dangerous visibility hazards on a motorcycle. Here is the definitive breakdown of modern anti-fog technology.
1. How Pinlock Technology Works
A Pinlock insert is made from moisture-absorbing organic plastic equipped with a silicone perimeter bead. When pinned inside the main visor, it creates an airtight double-pane insulation layer—much like a double-glazed thermal window—preventing temperature differential condensation.
2. Pinlock Levels: 30 vs 70 vs 120
- Pinlock 30: Baseline entry-level insert with moderate moisture absorption. Suitable for temperate climates and dry riding.
- Pinlock 70: The industry standard for touring and commuting. Provides strong fog resistance in damp conditions.
- Pinlock 120: Developed originally for MotoGP and WorldSBK racers. Utilizes maximum moisture-trapping capacity to remain completely clear during torrential rain and extreme cold.
3. Transitions & Photochromic Visors
Photochromic shields (such as the Transitions Adaptive Face Shield) contain light-reactive molecules that darken when exposed to ultraviolet radiation.
- Benefits: Eliminates the need to carry two separate visors (clear and dark smoke) for day-to-night transitions.
- Considerations: Temperature sensitive (reacts faster in colder weather) and will not darken behind tinted car windshields.
