AERODYNAMICS

VENTILATION
Motorcyclists live in a stream of moving air, which is precisely why every SHOEI model undergoes extensive aero- dynamic testing in SHOEI’s very own wind tunnel. In addition to the shell, the aerodynamic efficiency of spoilers and vents are also analyzed in SHOEI’s wind tunnel for optimal per- formance. As a result, every SHOEI helmet boasts an aero- dynamic design that increases air flow and reduces noise, buffeting, and lift, ultimately increasing performance and overall rider comfort.
An integral part of the development process, SHOEI’s ventilation systems direct cooling, moisture-drying air into the helmet, and utilize areas of negative air pressure to the rear of the helmet to draw warm, damp air through the outlets and into the outside environment. Perfect shape and placement of vent inlets and outlets, along with air channels buried within SHOEI’s Dual-Layer EPS Liners, are the basis for optimum ventilation, and are a significant part of what separates SHOEI from the competition.
SHOEI’s QR-E Base Plate System is one of the most advanced shield attachment mechanisms in the world. The simple shield release makes it easy to change your shield as conditions dictate. Also, widely appreciated is the convenience of SHOEI’s shield fine tuning adjustment dial. Each time the shield is lowered, the spring-loaded base plates pull the shield back to contact the window beading evenly, ensuring a wind and waterproof seal. QR-E BASE PLATE SYSTEM

The CWR-F shield, featured on SHOEI’s X-Fourteen helmet, sets a new standard in shield aerodynamics; like the Qwest helmet’s CW-1 shield, it is both taller and wider than the CX-1V it replaces. Both shields protect riders from 99% of the sun’s damaging UVA and UVB rays, and the CW-1’s three dimensional injection-molding process ensures distortion-free vision. All four shields work in conjunction with SHOEI’s optional Pinlock ® system to deliver fog-free vision in even the most challenging conditions. The RF-1200’s and RF-SR’s CWR-1 shield offers all these features, plus innovative ribs on the top and bottom edges of the shield that improve rigidity and eliminate bending occuring from wind pressure, as well as opening and closing. The Pinlock ® -ready CWR-F and CWF-1 shields provide a flat surface to accommodate tear-off sheets, while still ensuring a tight seal between the shield and the helmet’s window beading. Tear-off posts on the flat shields allow for tear-off tension to be adjusted without tools, making it easier and quicker to adjust racing tear-offs. The CNS-2, for the Hornet X2, and CNS-3, included with the NEOTEC II and GT-Air II, comes equipped with the Pinlock ® EVO fog-resistant system, protects from 99% of the sun’s damaging UV rays, and provides improved air/water sealing and noise reduction.
