Samurai (侍) were the military nobility and officer caste of medieval and early-modern Japan. In Japanese, they are usually referred to as "bushi" = "武士" (Chinese character)

By the end of the 12th century, samurai became almost synonymous with bushi and closely associated with the middle and upper echelons of the warrior class. Samurai were retainers with a clan and their lord and were trained as officers in military tactics and strategic advisors.

Samurai were a warrior class that hold loyalty, to the point of preferring self-sacrifice over dishonor. Toyotomi Hideyoshi was Oda Nobunaga's retainer, and Tokugawa Ieyasu was Hideyoshi's retainer. They fought to preserve the clans of their lords, but eventually gained power themselves.

ARAI SZ RAM 4X Frontal Air Ventilation

To harness the effective use of negative pressure to expel hot stale air when riding, ARAI SZ RAM 4X helmet adopt innovative ventilation system to transfer heat from inside of the helmet to outside. There are six holes on top of the helmet. The two frontal air vents for air intake and the remaining four holes force the hot stale air out to the back of the helmet. The central mounted air diffuser for ARAI RAM 4X is gigantic compared to older RAM 4 helmet and you can control/stop the introduction of airflow.

The function of the central mounted diffuser is to suck the hot stale air out rather than the conventional method of trying to force fresh air into the helmet. In addition this TYPE-12 ventilation system allow air to flow smoothly on the intake side. The newly designed TYPE-12 ventilation system also enhanced the quietness of the front air intake.

ARAI SZ RAM 4 Back Air Venting System

Changes to the quick release visor have increased peripheral vision while the switches on the helmet airvents are now bigger, making them easier to operate wearing gloves. Between the trademark twin diffusers is now a five-position air wing, designed to reduce drag, turbulence and buffeting. You can see how the airflow is passing through the top of ARAI SZ RAM 4X helmet and expel through the dual rear exhaust.

ARAI SZ RAM 4X Side Air Venting System

ARAI SZ RAM 4X helmet shape is carefully designed by ARAI to further enhanced and streamlined the flow of air through the side pods. Thinner visor shield side pods provide a more aerodynamic shape on ARAI SZ RAM 4X.

It is very common to have heat buildup inside the ear area around the helmet. ARAI SZ RAM 4X helmet utilize the fully adjustable Type-10 diffuser system where hot air can be expelled out through the side vents.
