Leatt GPX 5.5 Composite Helmet


This week we are taking a look at Leatt’s first ever motocross helmet, the GPX 5.5 Composite. To begin with, this helmet is not available until November and though we have put our hands on some pre-production units, we haven’t worn or ridden in one yet. Leatt also makes a GPX 6.5 Carbon version that has the same features, but has, as the name implies, a carbon fiber shell.

There are a few features of the GPX that make it stand out amongst the throngs of off-road helmets available. We’ll start with the main feature, what Leatt calls 360 Turbines. These are soft, round, rubbery dampers that are designed to flex in all directions and to compress during an impact, effectively “reducing head movement in the helmet.” These are spaced around the helmet between the foam and the fabric liner, so the rider’s head is actually in contact with the turbines. The helmet also has a multi-density foam construction to deal with medium- and high-energy impacts.

Leatt wanted to make an overall smaller helmet and they claim that the GPX is 10 percent smaller than other helmets on the market, and they also claim that this transfers less force to the neck and has less momentum in the event of a crash. The rear of the helmet is shaped in such a way that it matches the contour of a Leatt neck brace and there are multiple ventilation channels molded into the foam. To further enhance ventilation, there are four massive grates on the back and top of the helmet. The honey-comb-like grates are made of plastic and Leatt insures us that in impact tests, these grates withstand the force of the metal spike used in the penetration test.

Lastly, the chin-bar of the GPX is “plumbed” for a hydro tube, a small detail but way cool and it shows that Leatt is paying attention to off-road riders’ needs. There is a recessed channel along the bottom of the left side of the chin bar that a tube slides in. You can use your own or buy the quick disconnect tube offered by Leatt.

All of these features look great on paper and make for a very technically impressive helmet. Once we get one in the office and put it through hours of riding, we'll have a full test in the pages of Dirt Rider.
