Product Details
The John Doe JD/One Frozen Carbon is an ECE 22.06 full-face motorcycle helmet combining the Frozen Carbon finish with a compact, 1970s-inspired shape. It is aimed at riders who want modern protection and comfort with genuine scope to change the helmet's look through John Doe's Multi-Lock system.
Why choose the JD/One?
The Multi-Lock mounting system accepts directly compatible JD/One visors, short or long sun peaks and blanking panels. Beneath the retro styling, a multi-part EPS liner uses different absorption rates, while the wide eye port, glasses-friendly interior and adjustable front and rear ventilation support everyday road use.

- Four outer-shell sizes: XS-S, M, L and XL

Helmet size and fit guide
Measure around the widest part of your head, passing the tape approximately 2 cm above the eyebrows and ears. This table includes only sizes configured on this Moto Central product.
| Configured size | Head circumference |

John Doe uses four outer shells across the range: XS and S share one shell, while M, L and XL each use their own. The published standard cheek-pad thicknesses are XS 35 mm, S 30 mm, M 25 mm, L 30 mm and XL 30 mm. Alternative compatible thicknesses are available separately, which can help fine-tune the fit after the correct shell size has been chosen.
What is supplied?
John Doe's published box contents list one JD/One helmet, one clear visor, one tinted visor and one visor cover. Size-specific cheek pads are fitted as part of the helmet.
Compatible optional accessories
Direct JD/One accessories include outer visors, long and short sun peaks, blanking panels, goggles, visor and peak fasteners, replacement inner padding and cheek pads. Check that any accessory is specifically listed for the JD/One before fitting it.
Product questions
Is this helmet road legal in the UK?
This listing is for the ECE 22.06 version. John Doe separately publishes DOT FMVSS 218 certification for US-market versions, but this does not mean every individual helmet carries both approvals.
Can a communication system be fitted?
Yes. John Doe states that the helmet is prepared for communications and speakers, although no intercom is included.
Can the lining be washed?
Yes. The inner lining and cheek pads are removable, replaceable and washable.
Is Frozen Carbon described as a full-carbon helmet?
No. John Doe's official specification describes the JD/One shell as an FRP and carbon composite construction, so this listing does not make a full-carbon claim.
Moto Central fitting guidance
A full-face helmet should feel evenly snug with no painful pressure points and should not rotate independently of your head. If you are between sizes or want help checking cheek-pad pressure, visit the Moto Central showroom for fitting support before riding in the helmet.
