Unit, traditionally known for apparel, made an unexpected announcement Tuesday evening when the company revealed the world’s first purpose-built freestyle motocross bike, Skycraft. The bike is the result of a collaboration between Unit and world-renowned motorsport entity Triple Eight Race Engineering.

Conceptualized by Unit cofounder Ian Everest, the Skycraft prototype was engineered by an expert team at Triple Eight, led by acclaimed technical director Ludo Lacroix.

With a central goal of weight reduction, Skycraft is constructed almost entirely from carbon fiber and titanium components. At just 165 pounds, the bike is more than 25% lighter than a standard motocross machine.

“The original design brief recognized the opportunity for an ‘out of the box’ product for freestyle motocross,” said Everest. “All other forms of motorcycle sports use purpose-built machines. FMX riders have no option but to adapt and heavily modify race bikes. It made sense to explore what an FMX-specific bike might look like. Being a concept motorcycle, it also meant we were not constrained or restricted by production or cost requirements. As an experimental platform, Skycraft will allow for test data and rider feedback to lead toward a potential production bike.”

The Skycraft concept challenges conventional motorcycle design rules with a heavy-duty, carbon fiber monocoque frame containing a fuel cell. The tail design has integrated grab handles and a forked seat. Engineering boundaries were pushed even farther with the silencer integrated inside a carbon fiber swingarm.

“We felt that weight reduction represented the best characteristic to provide to riders in their quest for bigger tricks, as well as helping them innovate new maneuvers,” said Everest. “The prototype we’re launching today is the product of a combined effort and the engineering foresight and expertise of Triple Eight Race Engineering’s Ludo Lacroix.”
