Like many helmet companies, 6D was started because their founders had a strong desire to create a new and better motorcycle crash helmet. They were founded in 2011 in Brea, California, with their name derived from an engineering concept called the 6 degrees of freedom – in the case of 6D helmets that means that the helmet shell can move independently of the head in 3 dimensions including rotation around each axis. 6D started creating dirt bike helmets but have since moved into producing helmets for road bikes too.
You’ll find all our reviews of 6D helmets on this page.
