Genuine Sena visor pinlock for the Sena Stryker helmet.

It's the official Pinlock® 70 insert, designed specifically for the Sena Stryker’s Pinlock-ready visor (product code DKS426). That means it only fits the Three‑Component pin system installed in that visor

It relies on a dual‑layer system: the Pinlock lens absorbs moisture, while the air gap sealed by silicone pins prevents condensation forming between the visor layers

Rated a “70,” it's the original, reliable everyday fog-resistant solution. Higher grades like 120 exist for more extreme conditions
