An open face helmet leaves the face exposed, which some riders prefer for shorter journeys, city riding, or a more classic look on a café racer or scrambler. It offers less coverage than a full face design, and riders who choose one should weigh that trade off honestly rather than assume it based on style.
A certified helmet carries a label inside the shell showing the standard it meets, along with a homologation number that identifies the specific model tested. This label is worth checking on any helmet, since it confirms the exact helmet in your hands passed the test, not just the range it belongs to.
A handcrafted helmet craftsmanship helmet shell starts with a base material, commonly fibreglass or a composite blend, layered and shaped by hand rather than produced purely by mould and machine. Each layer adds strength, and the shaping stage is where a lot of the time in production actually goes.
The result takes longer to arrive than an off the shelf helmet, and that is by design. A made to order piece is fitted, finished and checked individually before it ships.
This is slower than fully automated manufacturing, and that is the point. A handcrafted shell trades speed for a level of finish and individual attention that a purely machine made helmet does not offer.
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.
