#1 Head safety

Povodom sve učestalijih crasheva po cesti, naletih na interesantan sajt o tipovim kaciga danas u upotrebi pa da podijelim.
Predstavlja nivoe zaštite koje različiti tipovi kaciga pružaju, kao i procentualno iskazane mogućnosti udara prilikom pada u predjelu glave, te zašto (ne)koristiti kacigu nakon oštećenja.
Full-face helmets wrap fully around your head, and offer the best protection both while riding, and in a crash. All full-face helmets that I'm aware of have a flip-up visor, which is typically removeable without tools. This is the type of helmet I own.
Flip-up helmets are a compromise between the protection of a full-face helmet, and the convenience of a 3/4 helmet. Being a compromise, they are neither as protective as a full-face, nor as convenient as a 3/4. However, if you can't stand the thought of a full-face helmet because of glasses, or being able to talk to people with your helmet on, a flip-up may be a good choice for you. I am personally undecided on them, but stay with a full-face because I don't feel hampered by it. A good flip-face helmet is a far better choice than a 3/4, so that's my recommendation.
The 3/4 helmet was very popular in the 1970s, when there was a huge surge in motorcycle ownership in the US. Full face helmets of that time were bulky and heavy, making a 3/4 helmet a much more comfortable choice. This is no longer the case, and 3/4 helmets are not a wise choice. They leave your chin and face exposed, both to oncoming objects like rocks and bugs, and to the pavement in a crash. Take a look at this diagram, which shows where crashed helmets took hits. Note how the area with the largest single percentage is the chinbar.
Half helmets, also called "brain buckets" and "puddin' cups" offer very little protection either in a crash or while riding. The market for these helmets seems to be cruiser riders who want to project a tough or scofflaw image. They have the greatest feeling of freedom of all types of DOT-approved helmets. If you value your life at all, avoid half helmets.[/img]

Visual examination may or may not reveal shell damage. Visual examination WILL NOT reveal liner damage. A damaged shell or liner greatly reduces the helmet’s ability to absorb further impacts.
