The jet motorbike helmet is a model without a chin strap. This protective equipment is perfectly suited to riders wearing goggles. It is also recommended for urban and summer use, provided that the two-wheeled vehicle has a limited speed. Available in several versions, this equipment is also characterised by its lightness compared to a full-face helmet. As it is a safety equipment, there are a number of criteria to consider when buying it.
Basic criteria for buying the right jet motorbike helmet
Size is the first important factor when buying a jet motorbike helmet. It must be adapted to the rider's head in order to provide maximum comfort. Opt for one size smaller because the foam inside will settle over time. As a result, it stays securely in place at all times. Weight is another factor to consider. It varies from 1,100 grams to 1,200 grams depending on the materials used by the manufacturers. The motorbike helmet can be made of thermoplastic, polycarbonate, fibre, multi-fibre or carbon. Avoid muscle fatigue by choosing a helmet with a reasonable weight. Ventilation is also an essential criterion since it helps to evacuate mist. Ventilation is also essential to avoid overheating of the jet helmet during the summer.
Other criteria to be taken into account when buying a jet motorbike helmet
A transparent screen gives you good visibility day and night. The catch that holds the screen in place must be firm and robust. An untimely closing or opening of the screen could indeed hinder you on your ride. As far as the watertightness of the jet helmet is concerned, it is ensured by a screen gasket which varies from one model to another. This element prevents the infiltration of water, especially when it rains. You can also opt for certain options such as bibs or a nose cover. These components offer additional protection against the weather. As for the microphone/headset, it allows you to communicate more easily with your passenger. The suitability of the options depends essentially on your needs. You should also consider the locking system. According to decree n° 2006-46 published in the official journal of 16 January 2006, you must always fasten your jet motorbike helmet while riding your motorbike. The automatic or micrometric system is the most common. It consists of a notched plastic strip and a flexible strap. You can also opt for the double buckle. This device is made up of two D-shaped rings. You have to pass the strap through both loops and then iron it through the first one to secure it firmly.
Certification, a crucial factor when buying a jet helmet
Only the approved jet motorbike helmet complies with current safety standards. It is the European standard ECE 22.05 which details the retention system or shock absorption. This obligation is stipulated in the Highway Code, article L. 431-1. It is valid both for the motorcyclist and the passenger of a two-wheeled vehicle. To recognise an approved jet helmet, look for a distinctive sign on the label. This is usually sewn into the chinstrap. The approval is indicated by the letter E surrounded by a circle. It is followed by a number designating the country of approval, in this case E2 for France. The other numbers indicate the serial number, while the letter J refers to the jet and half-jet type helmet.
