DUKE II comes with the dual homologation P/J which allows you to ride with the chin guard open guaranteeing safety thanks to the lever P/J on the left-hand side of the helmet. This lever, when in the “J” position, blocks the chin guard in the fully open position avoiding the chin guard to accidentally close. Thanks to the reduced dimensions of the helmet, the weight of DUKE II is only 1550 gr +/- 50gr.
