★  About CM-2-P UIC shield

Heat-shielding material by TEIJIN LIMITED is adopted on "UV & IR cut shield"

"UV & IR cut shield" uses high-performance polycarbonate of TEIJIN LIMITED as its material. This mateiral cuts UV (ultraviolet) and reduces IR (infrared). It has a heat ray shielding performance that suppresses the temperature rise due to the solar heat generated by the infrared rays (IR) of sunlight, and reduces the heat conduction to the inside of the helmet while maintaining the "clear visibility" that is the most important performance for helmet visor.

* Incandescent lamp (300W) is irradiated to measure the temperature inside the helmet (in-house test).

Temperature suppression effect inside the helmet*


RYUKI is equipped with a "CM-2 Inner Sunshade" that can be opened and closed to reduce glare by the smoke lens effect, such as in the morning and evening with strong reflections and in the daytime with strong sunlight. This makes urban riding and touring more "comfortable" by improving visibility and reducing eye strain.




By increasing the size of the breath guard, the clearance with the inner sunshade has been narrowed. This reduces glare caused by changes in riding posture and sunlight. In addition, the air outlet on the inside of the shield is also made large to improve the efficiency of ventilation performance.
