ECE 22.06 Explained: What Helmet Certification Actually Means
For helmet care products and guidance, see my homepage.
Most manufacturers recommend replacing a motorcycle helmet every five to seven years even without a crash, since the internal materials that absorb impact degrade slowly with heat, sweat and UV exposure. The shell can look fine while the protective layer underneath has already lost some of its effectiveness.
The liner deserves the same care. A removable, washable liner keeps the inside fresh, and following the maker's washing instructions protects both the padding and the stitching around it.
ECE 22.06 is the current European standard that motorcycle helmets are tested against, and it replaced the older ECE 22.05 standard with a wider and more demanding set of tests. Helmets are checked for impact absorption at multiple points on the shell, not just the crown, and the standard also tests rotational forces, which earlier standards largely ignored.
From there, the build follows the same certified construction as the standard range. Made to order does not mean a shortcut around testing, it means the standard process is carried out around one person's measurements and preferences instead of a general size run.
Anti fog inserts and coatings help in cold or wet conditions, but they are not a substitute for a visor in good condition. Once scratches build up to the point where they catch the light on every ride, it is time to replace rather than keep cleaning around the problem.
