The Stilo ST5 Peak is available as an optional extra for any ST5 helmet.
A standard carbon and 8860 version is available with the main difference being the size of the carbon weave to match the helmet construction. If you wish to use the ST5 Peak with a visor you will need to add the optional YA0864 fitting screw kit as a longer screw is required.
The ST5 Peak is designed to block the sun and is often used in the NASCAR series.
