The Stilo ST6 Formula visor (part YA0905) is the replacement and spare lens for the ST6 F and ST6 FN open-cockpit circuit helmets. The formula visor has a shorter profile and different cut compared to the visor used on the ST6 GT and GTN closed-cockpit helmets. The two are not interchangeable: confirm your helmet variant is an F or FN before ordering.
The tool-free quick-release visor system on the ST6 accepts the YA0905 without modification. A spare visor is useful for drivers who run different lens tints between morning practice and afternoon qualifying, or who want a backup in case of stone damage on circuit. The YA0905 is the clear standard replacement; tinted and anti-fog variants are listed separately.
For ST6 GT and GTN helmets, a different visor part number applies. If you are unsure which visor your helmet takes, the attributes tab on the helmet listing names the visor type. Contact us with your helmet’s part number if you need confirmation before ordering. If you need to confirm lead time or a specific size before ordering, drop us an email or click to open a chat and we can check availability.
