Went to a motorbike shop today to look at some helmets (I should really get the bike first....but we won't go there....). The bike shops cheapest helment was around 0 and the most expensive was 0...which begs the question..why the big difference and which one should I go for? I don't know what I'm looking at when buying helments because they all look the same to me? Maybe I'm a little new to this motorbike business, but ifs a 0 helment does the job, then why would you spent 0? I'm not trying to be a smartase over this, I jiust need some help? (also what brands are good/bad) Thanks Andrew (who needs a hand to talk his wife around to the fact that I NEED a motorbike....)
