Product test : Keeping a cool head

By the staff of Dirt Wheels .

LS2’s Subverter helmet is a striking-looking lid. The fit runs small, but once you find the right size, it is comfortable and the venting is exceptional.


LS2 makes a wide range of helmets for different uses. This LS2 MX470 Subverter is primarily an off-road motorcycle helmet, but it is a great choice for quads or UTVs as well. The MX470 Subverter full-face motocross helmet uses LS2’s proprietary Kinetic Polymer Alloy (KPA) for the shell. KPA is lightweight, and it has a small amount of flex as part of the energy management system. But, in this case, the biggest feature of the three different shell sizes is a whopping 35 vents!

The Subverter has the removable earpieces that are required by most race organizations. This padding can be removed with the helmet on.


LS2 opted for the three shell sizes (for helmet sizes XS through XXL) to make sure that each size is as small and light as possible. There are a lot of features packed into this helmet, so it weighs in at 3.2 pounds. The look of the helmet is unique since many of the shell’s 35 separate ventilation ports are molded and inserted into the shell surface. They work with channels that are molded into the multi-density EPS but are under the eye-searing colors of the comfort liner and padding.

Naturally, the comfort padding liner is removable and washable. The helmet also has the emergency release system for the cheek pads that many race organizations require. The eyeport should have room for any contemporary goggle design, and the field of vision is wide. Instead of merely riveting the chin straps to the shell, LS2 uses a triangular metal security plate to reinforce the riveted joint.

Safety is vital, and the Subverter meets or exceeds DOT (U.S.) and ECE (European Union) certification.

Check out all of the exhaust venting at the rear of the LS2 Subverter. There truly is a lot of detail in this helmet.



The LS2 Subverter has an intermediate oval internal head-form shape, but the helmet still runs small. We wear a full size up from what we normally select in other helmets. We find the Subverter to be a striking helmet with bright, clever graphic combinations. As colorful as the outer shell is, it almost fades when compared to the multi-color neon colors of the comfort liner.

The helmet goes on easily enough, and it has a snug fit against your face. Riders who wear glasses found that the ear and cheek pads hold the glasses in place. It does that without ever having uncomfortable pressure on the face. The visor is easy to adjust with a good range, and it is open enough that high-speed running never pulls on your head. The LS2’s DOT-approved, quick-release helmet buckle system is easier and quicker to use than typical D-rings.

The Subverter is available in a wide range of colors and patterns, and it comes with a soft helmet bag. Prices range between $199.98 and $299.98 depending on color and graphic design you select. To look at LS2’s lineup of helmets, go to or call (888) 968-9888.
