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 and 50% respectively (value for reference measured by in-house facility). Greatly increased aerodynamic performance can do a lot to ease riders #39; fatigue. Marc Marquez joined wind tunnle experiment at over 200km/h for development. X-Fourteen / X-Spirit III Aerodynamic Performance The values are of comparison with X-TWELVE (value for reference measured by in-house facility). LIFT, the force of moving upwards, is -3. YAWING, rolling force caus
