While all helmets have to meet minimum safety standards, research shows that up to 50 lives could be saved each year if bikers wore the safest helmets available to them.
This is where SHARP comes in...
Each helmet is purchased from an actual store to ensure they're the same ones as we can buy ourselves.
They're then rigorously tested, with SHARP performing 32 tests on 7 helmets across a range of sizes, and given a star-rating out of 5 according to how well each helmet could protect the brain in the event of a collision.
Daily: Even though it's a pain, clean your helmet each day - especially your visor. If flies or dirt get on it your vision will be seriously reduced next time you ride. Remember: if your visor becomes scratched, replace it immediately.
Weekly: Each week clean the vents and intakes - if these clog up with dirt, they won't be anywhere near as effective.
Monthly: If your helmet has removable linings or cheek pads it's worth cleaning these each month, but check the manufacturers guidelines first as some may have certain washing instructions.
Ok, so the helmet you want may look awesome but it's useless if it doesn't fit you properly. Wearing a helmet that fits correctly massively increases your chances of surviving a collision. Take a look at the guide below for more detail:
