HJC Motorsports is proud to unveil their newly redesigned super-lite SI-12 Helmet, now called the Si-12R. The new Si-12R is still one of the lightest helmets in the market weighing in at approximately 1500g (3.2 lbs). The Si-12R comes with the HJC's “ACS” Advanced Channeling Ventilation System, which allows air flow through the durable, lightweight titanium top front vent, and flushes the heat and humidity up and out the rear exhaust, to keep your head cooler during the entire race.

Even with the ACS system a driver will still sweat on a hot day, which is why HJC redesigned the new Si-12R with a removable and washable fire retardant and moisture wicking interior. In addition, the newly designed interior will now give the option of using ear cups (sold separately) to help reduce the outside noise decibel levels and adapt for radios.

Other advantages of the new Si-12R include; pre-drilled holes for head and neck restraints, polycarbonate injection molded shield with tear off posts and a deluxe helmet bag to make sure your helmet stays in great condition. The Si-12R is Snell SA2010 approved. Its available in sizes XS-XXL, colors available are white or rubbertone.
