The Bell Star MIPS Tantrum TItanium motorcycle helmet is made from an ultra-lightweight Tri-Matrix composite shell with six shell and EPS sizes for maximum comfort, aerodynamics and minimum weight. Each helmet size is a separate shell size. It utilises Bell's MIPS energy management system (multi-directional Impact Protection System) that reduces rotational forces resulting from specific impacts. The X-Static XT2 silver liner wicks moisture and keeps you ultra-comfortable with Magnefusion magnetic cheek pads and integrated speaker pockets. The Panovision visor with Class 1 optics is anti-scratch treated for superior vision, plus the liner is eyewear friendly. The visor port has a Streetview orientation or a wider aperture and field of vision. Includes a dark visor and a Pinlock insert.
