This might just be the best motorcycle helmet for the price range it is listed in that you can buy. In 2008 motorcycle riders worldwide saw the release of the most anticipated motorcycle helmet in years, the OGK FF-5. This helmet took 3 years of development to produce, and incorporates many unique features and superior design and materials.
Sizing has changed from earlier FF-3 and FF-4 variants,with the FF-5 closer to Arai RX-7 in size and shape (if you wear an M in Arai RX-7 for example, please choose FF-5 sized M.) Construction and materials have changed considerably from the FF-4 motorcycle helmet, with an all new interior with a feel and comfort that puts this motorcycle helmet in a class of it's own. Cost is about $365 which is a great deal for a motorcycle helmet as cool and technologically advanced as this one.

The FF-5 carries the Japanese SG safety standard (highest in the world) and also carries the MFJ standard(Motorcycle federation of Japan) which is a race standard that only the highest quality riding gear and helmets carry (for example RS Taichi and Kushitani leathers.) The FF-5 is one of the few helmets to also carry the FIM standard, which means this helmet is approved for World Superbike and Moto GP racing as well as all FIM approved events.
