The reigning king of full-face helmets, the D4 range expands with a Polyacrylite model packing the same safety and comfort features as the premium carbon and composite models into a price-conscious shell.

Light Speed to the Podium

When performance is measured by the millisecond, there’s no time for nonsense. Worn by the world’s fastest racers, Sprint Ultra is designed specifically for the moments between the tape when a fraction of a second can make or break the day. The only kit with the slim cut Precision Fit, Sprint Ultra’s premium Troy Lee Designs Ultra fabrics are made of the lightest materials with laser-cut ventilation, prioritizing speed and function.

Dedicated to the Details

Sprint is to the dedicated racer what fuel is to fire — essential. Striking a balance between snug and relaxed, Sprint’s crafted Race Fit cut leans on years of athlete feedback with improvements in lightweight poly mesh fabrics for better ventilation and mobility. From practice laps or out of the start gate, Sprint’s finer details dominate to the finish.
