Highlighted in orange: the winner of each measurable spec. Manufacturer data.

The chin bar: 180° vs flip-up

  • Advant X: the chin bar rotates 180° to the back of your head. Open, the helmet works as a proper open-face, with no raised chin bar catching the wind.
  • Strobe II: a classic flip-up chin bar that lifts and sits above your forehead.

If you will often ride with it open, the Advant X is more comfortable.

Weight: the Advant X wins

1,600 g for the Advant X against 1,700 g for the Strobe II, according to LS2.

Shell and materials

  • Advant X: HPFC composite, two shell sizes.
  • Strobe II: KPA thermoplastic, three shell sizes. Better proportioned in small sizes.

Pinlock: the Advant X wins

The Advant X comes with a Pinlock 120 Max Vision in the box; the Strobe II is Pinlock ready.

Price: the Strobe II wins

The Strobe II is the more affordable of the two.
