HJC i40N

The HJC i40N is a compact open-face motorcycle helmet with an Advanced Polycarbonate Composite shell, a long Pinlock-prepared XD-15 outer visor, an integrated dark smoke sun shield and a removable, washable interior. Moto Central's collection includes solid colours, Dova, Pyle and Vision graphics, plus compatible XD-15 visors and DKS281 Pinlock inserts.

It is aimed at urban and everyday riders who prefer the airflow and broad outlook of an open-face helmet but want more face coverage from a full-length external visor. The clear shield helps manage wind and road debris, while the internal sun shield can be deployed when light conditions require it.

HJC i40N features at a glance

Who is the HJC i40N for?

The i40N suits commuting, town riding and relaxed journeys where easy visor operation, compact dimensions and open-face airflow are priorities. Its long XD-15 provides more weather coverage than a short bubble visor or peak, and the large upper ventilation control is positioned for operation while wearing gloves.

The most important choice is the protection format. The i40N does not have a protective chin bar, so the chin and lower face remain more exposed than they would be in a full-face or closed flip-front helmet. Riders who prioritise maximum facial coverage should compare those formats before choosing on style or convenience.

Shell, ventilation and retention

HJC's Advanced Polycarbonate Composite construction is shaped for a compact urban profile. A large closable intake at the top supplies airflow around the crown, although the amount felt by the rider will vary with speed, motorcycle screen, head position and weather.

The one-touch micro buckle allows incremental adjustment. It should be tightened so the strap sits securely under the jaw without restricting breathing or normal head movement. Check the buckle engagement and strap condition before every ride.

XD-15 outer visor and DKS281 Pinlock preparation

The i40N uses HJC's XD-15 outer visor. HJC lists this shield as anti-fog-lens prepared, and Moto Central carries clear, dark smoke and iridium replacements. The RapidFire ratchet system permits tool-free removal, but both pivot points must engage fully and the shield should close evenly against the eye-port seal.

Pinlock identifies DKS281 as the Pinlock 70 MaxVision insert for the HJC i40 visor. Moto Central's DKS281 listings are shaped for the XD-15 used across the listed i40 and i40N applications. Match XD-15 on the outer shield and DKS281 on the insert rather than ordering by brand alone.

Pinlock-ready does not necessarily mean an insert is included with every helmet. Check the supplied contents on the exact colour and size product page. A clear insert adds anti-fog performance without intentionally darkening the view, while a dark smoke insert also reduces incoming light.

Clear, tinted and iridium visor choices

A clear XD-15 is the practical option for mixed conditions, poor weather and night riding. Dark smoke and iridium blue, gold or silver finishes reduce or alter transmitted light and are intended for suitable bright conditions.

UK road-use requirements apply to visor markings and light transmission. Check the product markings and carry a clear alternative if a journey may continue after dark. Avoid placing a heavily tinted DKS281 behind a dark or iridium outer visor, as combining tints may reduce visibility too far.

Integrated sun shield

The internal dark smoke shield provides a separate layer of light reduction behind the clear outer visor. Before buying, try it while wearing any spectacles used on the motorcycle and check that it does not touch the nose, eyelashes or frames.

HJC documentation can show different sun-shield references for different i40-family versions and markets. Order an internal replacement only after checking the code on the existing part or the documentation supplied with the exact helmet. The IS-11 listing in Moto Central's separate i40 collection is specifically described for the original i40 and should not be assumed to fit every i40N.

Choosing the correct i40N size

HJC lists the i40N from XS to 2XL, with availability varying by colour and graphic. Measure around the widest part of the head just above the eyebrows and ears, then compare the result with the chart on the exact product page and our motorcycle helmet sizing guide.

The helmet should feel evenly firm around the crown and cheeks without a concentrated pressure point. Secure the micro buckle, then gently rotate and roll the helmet. The lining should move the skin rather than sliding freely, and the helmet should resist being pulled forwards off.

Keep it on for several minutes and check the forehead, temples, lower edge and glasses area. Operate both visors during the fitting. A familiar size from another HJC model is only a starting point because internal shape and padding can differ.

Interior and visor care

Remove the crown and cheek pads using HJC's fastening sequence, wash them gently and allow them to dry naturally. Do not use direct heat or strong detergent, and never cut the protective EPS to create space for accessories.

Clean the XD-15 with water, mild soap and a soft cloth. The Pinlock insert has a softer moisture-absorbing surface, so rinse loose dust away and avoid abrasive cloths, paper towels and chemical visor cleaners. Replace any shield that is cracked, insecure or badly scratched in the normal field of view.
