This system 6 helmet has had VERY LITTLE use. Probably 5 rides before I decided to sell my GS. The helmet is flip front style with built in sun visor. The main visor is anti fog and it is very effective even on cold days.
Its also mega comfortable and supposedly very safe. It has also been noted as the quietest helmet money can buy form multiple motorcycle magazines. Size 56/57. Loads of vents for cooling. All the liners are removable for cleaning. Comes with BMW carry bag.
