Size Guide


Wearing a helmet of the right size is important because, if it is not the right size, its primary function of protection loses effectiveness.
First of all, a helmet that is too small or too big would definitely be uncomfortable and, furthermore, a helmet that is too small would also be unable to protect the nape of the neck, whilst a helmet that is too big, as well as moving around irritatingly on the rider’s head, could also move and not cover the head correctly on impact, in the case of a fall. To check if a helmet moves out of its correct position once it is in place, shake your head gently with the chin strap secured: if the helmet stays put, the size is right.
KEP Italia produces helmets with the outer shell available in two different sizes, which, in turn, house all the various size of inner cap, based on the thickness. The medium outer shell can be fitted with eight different sizes, from 51 to 58, whilst the large shell holds sizes 59 to 62.
Head size is measured using a tailor’s measuring tape, passing it round just above the ears and in the middle of the forehead.
But the right size of helmet is not enough; it must also suit the shape of the rider’s head.
Indeed, it is possible to insert small separators into the helmet to adapt it to fit the head of the rider (that can be oval, round or egg-shaped) perfectly and can be inserted at the front, back or on the sides of the inside of the helmet. For this reason, KEP Italia has created ten linings for oval heads (typical in Europe) and twelve linings for narrow heads (typical of North America and Canada).

It is important to remember not to ride using someone else’s helmet, unless the size is a perfect match to your own. We discourage the purchase of second-hand helmets, insofar as we cannot be sure of its condition or protective capacity.
