K-5 is the new AGV fiberglass and carbon fiber helmet, a point of reference for sports use, but at the same time extremely comfortable. It has been designed taking into account the AGV Extreme Standards, to maximize performance and comfort. The fiberglass and carbon fiber shell guarantees resistance and lightness, while the lines are aerodynamic and streamlined, in true AGV style. Comfort is ensured by the perfect fit, and by the easily operated inner visor. Size is minimized thanks to design studies carried out on racing helmets and the integrated rear spoiler provides excellent stability even at high speed.
Shell: The external shell is made of fiberglass and carbon fiber. The shell is available in two sizes. The inner EPS are available in four sizes. Each size has four different densities, to always guarantee the best safety-lightness ratio, and optimum comfort for each size.
Ventilation: The IVS (Integrated Ventilation System), designed using CFD analysis, features ducts hollowed into the shell for improved air circulation inside the helmet and better aerodynamic efficiency. The use of two front side air intakes, together with another large central air intake, integrated in the shell profile, ensures a consistent flow of fresh air inside the helmet. The back extractors remove the hot moist air inside the helmet, and are fitted with a new on/off system, developed in the wind tunnel, for optimum ventilation.
Visor: Depending on the size, K-5 offers two types of visors: GT 2.1 for sizes XS, S, MS and GT 2 for sizes ML, L, XL, XXL. This guarantees perfect adhesion with the shell at all times, to avoid draughts and noise. For this purpose, the visors are also fitted with the new visor edging, which further improves seal and insulation. Visors are treated to prevent scratching and misting, and 100% UV-ray protection is also guaranteed. There is also a new patented micro-opening system, easily operated using a button on the chin guard. This system gives the possibility of locking the visor in the slightly open position, for increased ventilation. The visor opening and closing mechanism has a XQRS system, for quick removal without using tools. K-5 also comes with an internal scratch-resistant, tinted sun visor, which can be removed for cleaning and replacing without using tools.
Inner Liners: The inner liners can be removed and washed and are made from a sanitized Dry-Comfort fabric to prevent the formation of bacteria and the onset of allergies. This fabric contributes to the rapid dispersal of dampness from the skin, the absorption of excess sweat and ensures the rider stays fresh even over long periods of time.
Functionality / Safety: The retention system has a double-D metal ring closing mechanism inspired by the racing world. K-5 is ready for use with the SHARE, the communication system developed by AGV.

1. Measure your head size. To do this, pass a tape measure horizontally around your head at a height of about one inch above your eye-brows and across the largest portion of the back of the head.
2. Check your measurement with the helmet sizing chart and select the closest size. As the helmet may not always meet your head size exactly, and your head measurement may fall between two sizes, first try the smaller size.
WHEN YOU RECEIVE YOUR HELMET
1. Expand the helmet opening by pulling outwards on each chinstrap, and slide your head into the helmet. If you are unfamiliar with helmets you may be reluctant to pull the helmet down, as it may feel too tight. Even if the helmet is difficult to put on, please use the smallest helmet possible. The helmet should feel snug. If the helmet is not tight, it is too big for you. New helmets will break in and loosen slightly over time.
2. Once the helmet is on:
Check that the helmet inner lining fits snugly all around your head.
Check that the top pad presses on the top of your head.
Check that the cheek pads press up against your cheeks. When you open and close your mouth, you should drag your teeth along the inside of your cheeks.
Check to make sure that you cannot easily slide your finger into the helmet along the side of your temple.
Hold the helmet with one hand on each side. Without moving your head, try to move the helmet up and down, and side to side. You should feel the skin of your head and face being pulled as you try to move the helmet. If you can move the helmet around easily, it is too big. Try a smaller size. Please note that during this check, the chinstraps should be properly fastened.
