Arai is the only company offering multiple interior-fit shapes to better address the infinite variety of riders’ head shapes and sizes.
No one pays more attention to the subtle variations and infinite possibilities of the human head shape than Arai. Why? Because it’s the secret to getting the best comfort and fit.
And Arai is nothing short of obsessed with putting you into the best fitting, most comfortable helmet possible – because that´s who we are.
The Quantum-X has Arai's ROUND OVAL (RO) interior fit shape. Shorter front-to-back and a little wider side-to-side (as compared to Intermediate Oval).*
