Pinlock support 185 different helmet bands with their lenses. I have used them for the last five years on many different helmets. In fact, when I think of the current helmets that I use, only one of the four does not have a pinlock lens!
Over the years, I have tried many other products (including self adhesive lenses), but none that I have tried are comparable to a pinlock insert.
Pinlock inserts were invented in 1994 but were initially slow to take off, however, popularity has been increasing rapidly in Europe, the United States, and Asia in recent years.
I couldn’t imagine riding my bike in a helmet without a Pinlock visor insert now, as it keeps my visor fog-free, no matter the circumstances.
So, what is a helmet Pinlock, and what’s so great about them? Everything you need to know is in this article.
Key points:
- A pinlock is a thin piece of plastic that is mounted by two ‘pins’ inside the helmet visor.
- A pinlock works like double-glazing to stop condensation forming on the visor.
- Pinlock inserts are specific to different helmet makes and models due to differing visor shape and sizes.
How Does Pinlock Work?
The Pinlock insert acts like double glazing for your helmet visor. Your motorcycle helmet needs to be Pinlock compatible and have two pins on each side of the visor, which is where the Pinlock insert fits into and the pins then hold the insert in place.
The insert has a silicon type edge all the way around which presses against the visor and creates an air-tight seal. It is the seal that stops condensation forming on the visor; the Pinlock insert itself also absorbs the condensation so it doesn’t form on the insert itself either.
The pins can be turned to ensure the insert is held tight and pressed against the visor, this is imperative to make sure the insert does its job.
The two key principles of Pinlock technology:
Moisture absorbing nanotechnology: The moisture absorbing surface effectively attracts and stores water molecules in humid conditions. In low humidity the stored water in the lens evaporates, creating room for new fog-free adventures.
Airtight chamber: The airtight seal prevents visor condensation by acting as a thermal barrier through the air pocket between the visor and anti-fog lens.
Three fog performance levels, to match your ride
Pinlock® lenses are available in three different anti-fog performance levels: 30, 70 and 120. From the weekend motor rider to the racing professional, Pinlock® offers the perfect anti-fog lens for your ride. The number symbolizes the fog resistance level of the insert.
