My name is Robert and today I would like to talk about viper RSV 151 BT+ helmets, Viper's latest vision to it's Bluetooth helmets 2014. As we can see that here we are talking is a multiple style helmet and flip up touring which is retractable inner sun-visor protected. It finches a drop down sun shade which is valuable for those late mornings and early evenings with sunshine. The colors available in this helmets are Yellow, White, Black, Matt Black, Silver and Gloss Black. Sizes available are XS and XL. Helmet has Aero-Tech venting system and a quick release visor system and protect if you look a closer look to the blue tooth system then you will see that there is a little button on the side which operates it. It's compatible with 99 percent of all helmets out in the market having a Bluetooth system in them. Most satellite navigation system and can be connected with 2 helmets with intercom with opt around 800 meters land of sight. Take a little closer in the interior of the helmet, The helmet features a Micromatic fasina for the perfect fit every time.
