The AGV range of helmets are very reasonably priced and are the same helmets that are worn by Valentino Rossi. Arai and Shoei are handmade helmets with some great looking designs and are priced accordingly. Box specialise in the budget end of the market and Caberg even have a range of helmets with a sunroof. If you're looking for an unusual open face helmet then try MOMO, although a few of the other manufacturers make open faced helmets. Craft on the other-hand make superb looking full faced helmets. Schuberth make some of the quietest helmets on the market and their quality is fantastic.
