Perhaps the best value on the market in a lightweight, MX helmet, LS2's Fast is a technically advanced weapon for serious off road riders. The shell is made from our technically advanced Kinetic Polymer Alloy, (KPA). This innovative material is ultra-lightweight and offers a bit of energy absorbing flexibility, but with a penetration resistance that rivals high-end composites.

Outer Shell: KPA
Certified: ECE 22.05
Weight: 1300 ± 50 gr
Shape: Long Oval
Removable & Washable Liner
Laser-Cut Foam
To ensure good protection the helmet must fit your head to perfection, special attention should be paid to the shell shape design and materials to minimize the effects of a possible impact. It is key to obtain a perfect fit to your head from outside to inside, as well as the shell, the configuration of the EPS liner, which should match closely the human head shape.

Helmet Sizing Tips

1. You should start by wrapping a measuring tape around your head about a half-inch above your eyebrows.

2. Since a helmet should be snug so it doesn't pop off if you crash, you need to pull the tape comfortably tight in order to achieve the best results.

3. Make sure you get precise results by measuring two to three times trying to get the same result every time. If you get different measurements take the largest one.
