The Helmet City guide to buying a Motorcycle Helmet
A poorly fitting helmet may not only be uncomfortable, more noisy and may move around when riding if too big or give headaches etc if it is too small, it is also dangerous. A helmet simply will not protect or perform as designed if the head inside it is not snuggly fitted against the impact absorbing material inside the shell.
Once you've decided on the helmet (we have thousands available!), to make a better judgement on size we would recommend measuring your head. Using a soft measuring tape, measure around the circumference of your head, across the forehead just above the eyebrows, above the ears and around the back of your head. Helmets are available in sizes from 50cm right up to 67cm! If you are say 58.5cm and a Medium is 57-58cm and a Large is 59-60cm, we would generally suggest going for the smaller size as the interior will compress over time. This is not a guarantee of course and we would always suggest popping to one of our Retail shops (or your local dealer) to try one on (we have 7 shops at the moment).
Another thing to bear in mind, is that a helmet in say size Medium from one Manufacturer may fit completely differently to a Medium from another Manufacturer. Therefore we would always recommend travelling to a dealer to try a number of different brands to get the perfect fit for your head shape.
If you purchase a helmet online from HelmetCity.co.uk, it can be returned (at your cost) as long as our strict Returns Policy is followed. The helmet can only be tried on (not used on the road), no pinlock fitted, no protective film or tags removed and the bag and outer box in the condition we sent to you.
Trying your Helmet on
When your lovely new helmet arrives, pop it on (after reading the advice sheet enclosed in the box) and wiggle it around to make sure the top of your head fits and is settled right in. Give the helmet a push from the front towards the forehead to see if it gives you any pain or discomfort. Do the strap up and tighten it until you feel it is quite tight (but not uncomfortable - you need to breathe!) Look in a mirror - how does it fit on the cheeks? If you can fit a couple of fingers between your cheek and the helmet cheekpads then it is too big, if it is pressing so tight your cheeks are between your teeth and you can't talk, then it may be too small! Please note that cheek pads do compress over time so they sort of 'wear in'. On some of the higher end brands, like Shoei and Arai for example, thinner and thicker cheek pads and even skull pads can be supplied - depending on the model. If you know the size you require at the time of ordering, these can be swapped out free of charge (Shoei and Arai only) - we keep the unwanted size. (this ONLY applies to Full Price Helmets).
If you are generally happy with the fit, leave the helmet on for a good length of time to ensure it is not pressing in places that are not immediately apparant. If a helmet is really pressing on your forehead this can sometimes cause a headache over time so it may be worth trying another size or brand.
It is important to read our Returns Policy regarding helmets and the Advice Sheet enclosed with your purchase, before going for a ride as a helmet cannot then be returned if it does not fit or you are not happy with it.
SHARP provides advice on how to select a helmet that fits correctly and is comfortable and information about the relative safety of helmets to help motorcyclists to make an informed choice. There is also a very informative Video on the SHARP website!
