Day after day our skilled Engineers apply enhanced tests to meet the needs of our customers. To achieve the highest quality standards, all of our products are subjected to stringent test procedures. To achieve the highest level of performance, staged aerodynamic tests are performed in our own HJC wind tunnel laboratory in parallel with live testing situations.
Optimised comfort and fit is an integral part of HJC’s helmets. Our product design and engineering are based on laser scanned profiles of real people for precision fitting. Beyond these measures, HJC helmets are tested to the extremes of International Test Standards for safety and protection. To exceed expectations, HJC in-house test labs are equipped with advanced test facilities to achieve the optimal level of aerodynamics, safety and performance.
Long standing MotoGP race-helmet design experience has made HJC designers and engineers experts in aerodynamics and wind ventilated helmets. Harmonizing the shapes and forms of a helmet with speed and wind resistance requires years of understanding and knowledge about the characteristics of airflow. With many years of heritage HJC engineered products set the standard in aerodynamic efficiency.
HJC Wind Tunnel Test Lab
HJC helmets are constantly tested in the laboratory as well as in “real” life situations to determine the highest quality standards. HJC is only one of very few helmet companies who are equipped with its own state of the art wind tunnel testing laboratory to test the aerodynamics, ventilation, noise, and more. In adapting motorcycle race technology to high-end road cycle helmets the HJC wind tunnel test lab constantly measures all the relevant forces in a variety of riding conditions.
Advanced Ventilation System
In order to achieve maximum ventilation, a technical adaptation of Bernoulli's principle is applied to aerodynamically enhanced models. In motion, the rate of surface flow in general increases towards the rear progression. Through pressure differences, cool air from the frontal intake is exhausted through the rear vent for internal heat dissipation, giving the cyclist optimum ventilation while riding.
1. The fluid energy preservation principle states that the sum of a fluid’s location energy, motion energy, and pressure energy is constant.
2. If fluid motion increases then pressure will decrease. Therefore as the sectional area where fluid passes gets smaller, the fluid motion speed will increase and the pressure will decrease
Advanced Exhaust Ventilation Performance
HJC helmets are designed and engineered using wind tunnel test verification analysis. From all perspectives, when riding, test results demonstrate that Furion exhaust ventilation outperforms all of our competitors
Optimum Drag Force
HJC helmets are designed and engineered to optimize drag force in wind tunnel testing. In comparison to competitor’s products, HJC Furion measures lowest in drag force testing and can save 7% more energy.
Advanced Air Channel System
Air channel is an optimal air passage within the inner surface of the helmet shaped and designed for maximum internal airflow. Depending on the rider’s speed, a certain amount of air will travel inside the helmet, through the frontal intake vent, along the inner air passage and out through the exhaust vent. Optimal air circulation through the air channel helps to cool the head from the heat generated while riding.
Internal Reinforcement Structure
Embedded within the EPS is a skeletal frame that is designed and engineered to bind the structure of the helmet together in the event of impact. The skeletal frame not only holds the helmet together but also provides rigid reinforcement for impact resistance.
In-Mold Construction is a method of binding the EPS together with the outer polycarbonate shell for greater structural strength. Binding the shell and EPS together enhances protection by providing compact reinforcement and gives an appealingly clean finish appeal to the product.
All helmets feature integrated special Polygiene Silver Salt (Silver Chloride) particles. Polygiene is an antimicrobial property and this natural ingredient has the ability to eliminate bacteria and fungal growth. Polygiene prevents the growth of odour-causing bacteria and fungi at the source, permanently. Prolonged odour control is possible because the natural elements are technically integrated into the fabric and will not wash out. Polygiene has applied its expertise and testing in the healthcare sector to ensure that there is no effect on the natural bacterial flora of the skin.
HJC Road Cycle Helmets are designed and precision engineered to achieve the lightest weight possible. Optimised thickness, density, placement and shaping, as well as materials and parts all contribute to the light weight construction. While retaining the aesthetic design our engineers constantly strive for the lightest possible helmet construction. Every day is devoted to breaking the limits and finding ways to advance product safety, comfort, and weight saving with inspired designs.
3D Laser Scan Precision Engineering
The profiles of a large sample of people have been 3D scanned and analyzed to determine the best foundation for precision engineered designs that suit a variety of head sizes and shapes from a wide range of ethnic groups and genders. Using this 3D scanned data to achieve close proximity to optimal comfort, HJC designers and engineers use 3 shell composite construction to develop the ultimate fit.
