Welcome to Saminastudio Study Racing Position, Increase Aero Dynamic Performance in High Speed X-Fourteen / X-Spirit III, developed putting much value on the use at circuits, sets the position where a rider strongly leans forward as basic position. The shell is designed by analyzing the riding wind running from front part of a helmet to rear, and then to back of racing suit at the wind tunnel facility. The edges and shapes on surface of a shell, rear stabilizer equipping rear flaps exchangeable depending upon riding condition and lower air spoiler are designed and equipped to maximally increase aerodynamic performance. Comparing values in wind tunnel experiment with its predecessor, LIFT, DRAG and YAWING decreased by 3%, 10% and 50% respectively (value for reference measured by in-house facility). Greatly increased aerodynamic performance can do a lot to ease riders' fatigue. Cheek Vent System Riding wind introduced from lower air intake runs through air route inside of chin bar and reaches to urethane foam directly from back side of cheek pad. It prevents hot air to stay inside urethane foam.
