Brand new SHOEI top-of-the-line model starts racing in the world.

Main Characteristics of X-Fourteen

Aero Form

Study Racing Position,
Increase Aero Dynamic Performance in High Speed

X-Fourteen, 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f fatigue.

Shield System

Tear-off Film Attachable Flat Shield – CWR-F Shield

X-Fourteen is equipped with newly developed flat shield, gCWR-Fh. Radius and thickness are finely decided in each area of the shield, and optical property is fully improved. CWR-F shield made of polycarbonate realizes a clear vision and advanced rigidity eliminating deflection and kink in high speed riding, Combination with QR-E shield base makes it easy to fix and remove a shield, and high airtightness is ensured in variable axis double action mechanism.


It is essential for comfortable riding to prevent fogging of a shield which occurs in low temperature or rainy weather.
Mist retardant PINLOCK® EVO lens is standardized in X-Fourteen. It covers almost all of a vision, and prevents fogging and secures comfortable vision in every condition.


Adjust Wearing Position of Interiors corresponding to Racing Position

The wearing position is different between upright riding position when riding on a standard bike and leaning forward position when riding on sport bike. Focusing on this point, the position of interiors of X-Fourteen can be adjusted in 2 steps depending on a riding position. By adjusting fixing position of center pad and cheek pad, the angle of riderfs head can be rotated forward by approximately 4 degrees from standard position, and as a result, it secures upper vision in leaning forward position. To ensure broader vision when leaning bikes in strongly leaning forward position gives riders great merit.

Individually Exchangeable Pad Makes Best Fitting for Every Rider

For X-Fourteen, the new interior system is introduced consisting of 6 center pads while each of them may be exchanged individually. This system realized best fit by exchanging each pad of front, rear, side, top, and neck to optional pad in different thickness to fit riderfs head shape. For a surface material of interiors, highly reputed HYGRA* with high performance of moisture absorption and quick drying and raised fiber in comfortable texture are used.
Cheek pad is equipped with E.Q.R.S. which makes it easy to remove a helmet in an emergency.
*hHYGRAh is a registered trademark product name of UNITIKA LTD.

E.Q.R.S.iEmergency Quick Release Systemj

Easy Helmet Removal System in case of an Accident

In an accident, it is difficult for a third party to remove a helmet from a rider. Although impact-absorbing performance and comfort are essential for a helmet, to support a third party giving aid to a rider in an accident is one of the important functions of a helmet. E.Q.R.S. (Emergency Quick Release System) developed by SHOEI makes removing of a helmet easy minimizing a load on a riderfs neck where is possibly injured by pulling strip.

Ventilation System

Strongly introduce riding wind, exhaust hot air and moisture effectively\ventilation system makes a rider feels wind.

Air intakes are equipped on 2 parts of X-Fourteen, front and upper areas, in order to produce an effect of ventilation system even in leaning forward position.
Air outlet holes of top air outlet and inside of rear stabilizer exhaust hot air effectively using negative pressure.
In addition, new air route is equipped in lower part of a helmet, and air introduced to lower air intake is divided in 2 ways. Upper part of a lower air intake leads air to inside of a shield and works as a defroster, and lower part of it leads air to cheek area where hot air and moisture may remain.

Shell & Liner

The sizes for X-Fourteen are set by the combination of 4 sized shells and 5 sized impact absorbing liner, and total 6 sizes from XS to XXL size.
AIM+ shell structure which is of complex layers of strong glass fiber and high performance organic fiber in high elasticity satisfies requirements of the safety standards easily. In addition to JIS, X-Fourteen is SNELL 2015 certified.
