Shoei X-Series Ultimate Guide

The 2024 Ultimate Guide To The Shoei X-Series

“For when milliseconds count.”

For over fifty years, Shoei’s helmets have protected the heads of champions. From the SR-1 to the X-Fourteen, and all of the models between, one thing has remained the same: each helmet that leaves Shoei’s facility in Japan is specially crafted and handmade to the highest safety standards.

History of Shoei: From Construction Yard to Wind Tunnel

Founded by Eitaro Kamata in 1959, Shoei began as a company that manufactured safety helmets primarily used in the construction field. A year later, Shoei expanded its facilities in order to begin its primary goal: manufacturing motorcycle helmets.

In 1962, Kamata and his company produced the first motorcycle helmets to meet the Japanese Industrial Standard (JIS). With this newly acquired certification, Shoei began development and production of motorcycle helmets featuring fiber reinforced plastic (FRP).

With newly developed helmets and a racing sponsorship program, Shoei introduced its very first motorcycle racing helmet in 1962: the SR-1.

The SR-1 paved the way for the extensive line of motorcycle racing helmets and helped to solidify Shoei as a premier helmet manufacturer in the motorcycle world. It was only four years later, in 1967, that Shoei started production of its first full-face helmet: the SR-Z.

Between the years of 1968 and 1978 Shoei began production of six new helmet models (the S-3, SA-1, S-10, S-12, S-20, and the GR-Z), and established factories in the United States and Europe to increase its market in the worldwide motorcycle helmet economy.

Since the development of its very first helmet, Shoei has helped to progress motorcycle racing helmet design and safety standards exponentially. With the introduction of the X-Fourteen helmet in 2016, the company is continually pushing the limits in the helmet industry.

Generation X: The Beginning of the Ultimate Racing Helmet

After 30 years of helmet creation and design, Shoei began its path down the road to the ultimate motorcycle racing helmet: the X-Series. In 1990 the company introduced the X-Eight; a helmet with a unique built-in mechanical face shield system. This feature completely eliminated the need for base-plate covers, making the helmet much quieter.

Three years later, Shoei released the first dual EPS liner ventilation system in the world with the introduction of the X-Eight Air, which laid the groundwork for one of the biggest helmet releases for the company: the X-Eleven.

With wind-tunnel development, an Advanced Integrated Matrix Plus (AIM+) shell, improved ventilation, extreme weight reduction and a comfortable interior, the X-Eleven was a major step forward for motorcycle racers and helmet manufacturers alike.

After the huge success of the X-Eleven, Shoei unveiled the X-Twelve in 2010. The launch included some brand new features, such as the improved base-plate system (Q.R.S.A.) for much easier shield installation and removal. The CW-1 Shield was also implemented to provide a taller and wider field of view, in addition to UVA and UVB protection from the sun.

But now, everything Shoei has done over the past six decades has come to fruition with the X-Fourteen. With all new aerodynamics, ventilation, adjustable lining, stabilization, and much more, the X-Fourteen was developed from the ground up. The helmet introduces an entirely new generation for Shoei, and brings to the table one of the best motorcycle racing helmets on the market.

Backed By A Professional Racing Team

The Shoei X-Series line of helmets have been used by professional racers since their inception. From MotoGP to the Superbike World Championship, the X-Series is used in a variety of different series and levels of road racing.

  • Marc Marquez

    After his first 125cc Championship in 2010, Marquez moved up to Moto2 and claimed the championship title in his second year in 2012. The title moved him up into the highest class, MotoGP, where he claimed back-to-back championships in his first two years for the Honda/Repsol team in 2013 and 2014.
  • Bradley Smith

    Beginning his career in the 125cc class in 2006, Smith progressed through the ranks and made his highest championship finish at second place in 2009. After a bump up into the Moto2 class, Smith found a foothold in MotoGP in 2013 and has been racing for the Monster Tech3 team ever since.
  • Eugene Laverty

    During his beginning in 125cc, Laverty was a runner-up in the 2004 British 125cc Championship. Following his success in 2006, he moved his way up into the 250cc class of the Grand Prix World Championship in 2007, and then to the World Supersport Championship from 2008-2010. In 2011 Laverty competed in the World Superbike Championship with Yamaha, which helped pave the way for his signing with Honda Aspar in MotoGP for the 2015 season.
  • Yukio Kagayama

    Starting his racing career in 1995, Kagayama has been on the track for the past decade. His resume includes time spent on teams in the Superbike World Championships, British Superbike Championships, and most recently the All Japan Road Race Championships.
  • Daijiro Kato

    After six years of racing in the All Japan Road Race Championship, Kato moved up the ranks to race in the highest class of MotoGP. However, in his very first GP class race at Suzuka, Kato was killed in a fatal accident after hitting the wall near the Casino Triangle chicane at close to 125 mph in 2003. In his memory, Shoei has released three different Daijiro replicas to honor the deceased racer.

The Shoei X Lineage: A Complete List of Variants

The helmets in the X-Series have been used by professional and amateur riders alike since its inception. Each model comes in a variety of different graphics, including race replicas of famous racing professionals. Note: a “replica” helmet is not just a decorative piece, but is made with the exact same safety features and graphics as the original.


Although considered by many to be just a stepping stone to make way for the X-Eleven, the X-Nine deserves recognition. Its upgraded ventilation system and shape helped make the X-Nine even more aerodynamic than the previous model.


Shoei set out to design a race helmet from the ground up, and the result was the X-Eleven. A complete overhaul of the X-Eight, the X-Eleven upgraded everything from the ventilation to a new shield locking system. Released in 2003, the X-Eleven was considered the “top racing full-face helmet of next generation.”


When the X-Twelve was introduced in 2010, it was the “flagship model” in Shoei’s helmet lineup. Used by professional racers such as MotoGP’s Marc Marquez and Bradley Smith, the X-Twelve was developed to perform at high speeds. The X-Twelve has both an innovative QRSA base plate and CW-1 shield technology, among many other advanced features.

Shoei X-Series

X-Fourteen: The New & Improved Shoei Race Helmet

The Shoei X-Twelve has been considered one of the best premium race helmets in the world; until now. In October 2015 at the AIMExpo Shoei announced the newest edition X-Series helmet: the X-Fourteen.

Shoei designed the X-Fourteen first and foremost for their professional racers, making it faster, safer, and more comfortable. With racers like Marc Marquez and Bradley Smith wearing it, you know that it’s a high-quality helmet. Shoei believes that the X-Fourteen shaves lap times, so much that the helmet’s slogan is “The X-Fourteen—When milliseconds count.”

What's The Difference Between the X-Twelve & X-Fourteen?

The X-Fourteen has several brand new features that make it even better than the X-Twelve. The shell shape has been redesigned to improve the aerodynamics of the helmet, including a brand new, patent-pending Rear Stabilizer. The Rear Stabilizer works to “maximize high-speed stability while reducing negative forces on the rider.” You will experience 50% less buffeting, 10% less drag, and a 3% lift reduction with the new X-Fourteen.

A few changes have been made to the face shield and shield locking mechanism. First, the CWR-F Race Shield (equipped with Pinlock EVO fog-resistant system) has innovative new ribs on the edges to help eliminate bending. The X-Fourteen now has a double shield locking mechanism, designed to prevent unwanted shield openings while riding. The QR-E Base Plate System on this helmet not only makes changing shields easy, but also blocks out unwanted water and wind when closed.

The X-Fourteen’s ventilation system has received several upgrades. Now the cheek pads have a new cooling “tube” that allows fresh air to enter the helmet, cooling the rider’s cheek area. Allowing cool air to enter the helmet isn’t enough, though. The side air outlets of the helmet have been re-positioned to better allow hot, moist air to leave the helmet. Overall, the X-Fourteen has six air intakes and six exhaust outlets.

The X-Fourteen: It’s All In The Details

When racing at a professional level, every single detail is important. That’s why when Shoei designed the new X-Fourteen, they left no stone unturned. The aerodynamics of the helmet can be customized by switching out the standard rear flaps with narrower ones. Shoei takes the customization a step further by incorporating an innovative five-stage rotating dial that allows you to fine-tune the shield and base plate.

Shoei prides themselves in “active safety,” which means that they don’t stop at meeting D.O.T. and Snell guidelines, but go further by designing products that are both comfortable and protective. The 6-layer AIM+ shell construction and multi-layer EPS work together to redirect impact energy in the case of a crash. An Emergency Quick Release System (E.Q.R.S.) is built into the helmet to allow medical personnel to safely remove the cheek pads and helmet from an injured rider’s head.

The 3D Max-Dry Interior is customizable with optional sizes for each section of the center pad. Made of Max-Dry material, the inside “absorbs and dissipates sweat twice as fast as tradition nylon.” The interior is completely removable, washable, replaceable and adjustable.
