This model is tested in Sharp laboratories and received 5 stars. Important factor other than stars is impact zone diagrams which is colours. Frontal bone, coronal suture, parietal bone, lambdoidal suture, squamous suture and temporal bone regions passed the test with green colour. SHOEI X-14(X-SPIRIT III) has ECE REG 22.05 safety certificate. Every helmet that passes Sharp test has this certificate.
SHOEI X-14(X-SPIRIT III) can keep up with developing technology in security with double-d ring chin strap system and visor lock system.
If we generalise user reviews for SHOEI X-14(X-SPIRIT III), we can rate isolation of this helmet as 6.8 over 15. You should not be surprised with different reviews. This is because we all have different hearing, riding style, motorcycle types. We all ride on motorcycle with different wind protection level and we all have different speeds. Wind tunnel test conducted by COAU at 100km/h identified noise level as 97.37 dBA and scores this helmet with 12.63 over 20. If noise level is an important criteria for helmet selection, we recommend taking dB levels of COAU as reference and see also: quietest motorcycle helmets
For air circulation, there are multi-channel single ventilation channel on chin side, visor has two ventilation channels, multi-channel single ventilation channel on the top, and six ventilation outlet channels on the back. Aerodynamic structure of this helmet is rated 7.56 over 10 by COAU and ventilation structure is rated as 8.83 over 15 by COAU.
SHOEI X-14(X-SPIRIT III) has pinlock. Therefore, visor fog will not be a problem. To keep visor clean in track conditions, visor has built-in tear off system. If we generalise user reviews for SHOEI X-14, we can rate wide field of view of this helmet as 15 over 15. Wide field of view may be similar in most of the helmets but vertical field of view is rarely similar. Therefore, vertical field of view should be considered as this is an important element. When you take position especially on sport motorcycle, you need as much as vertical field of view to see in front of you clearly. We can say vertical field of view of SHOEI X-14(X-SPIRIT III) is at good level. Vertical field of view of this helmet is rated 5 over 5 by COAU and visor wind proof level is rated as 5 over 5 by COAU.
We can say that SHOEI X-14(X-SPIRIT III) is designed for Intermediate Oval head structure and fitness of this helmet is at medium level. From outside, helmet will look neither larger nor smaller than your head.

|Helmet Type It specifies the type of the helmet, such as full face helmets and modular helmets… However, full face helmets are the safest type of helmet in the world.||Full Face|
|Origin Specifies the country that the product belongs.||Japan|
|Material Specifies the material type of the helmet.||Carbon Fibre|
|Weight Specifies the weight of the helmet. Even though a weight of 100 grams seems light, it creates a serious load coefficient, when factors like wind coefficient are added to this weight.||1 40 kg|
|Sharp Rating Sharp is a company that was founded in 2007, which is controlled by the British Government and puts helmets through durability tests. They have always raised question marks as some models of upper class brands were given low ratings. Nonetheless, they are an independent institution that rates helmets by testing them all in the same way.||5 Star|
|Snell Certification Snell is a non-profit organization that was built in USA in the year of 1957. Snell tests are truly vigorous and challenging. Some models of the brands like Arai, Bell, Shoei, Hjc have passed this test. The number of helmets that could pass this test is limited. Snell standards are renewed in every 5 years.|
|Chin Strap It is the chin strap of the helmet. They are categorized as Micrometric or Double D Ring. Double D Ring fastening system is the one that is being used in MOTOGP. It is present in professional helmets and it is the safest fastening system.||Double D-Ring|
|Visor Lock If you are planning on using your helmet while driving with a speed of 240km/s or more, we definitely recommend you to get a helmet with visor lock. Otherwise, the force applied by the wind may open the visor of the helmet.|
|Pinlock Pinlock is perhaps one of the greatest technologies. It completely prevents the fog on your visor that is caused by moisture, your breath or the cold weather. Your vision is never restricted. It is not provided with all helmets.||Included|
|Emergency Kit Emergency Quick Release System. It is the system for quickly removing the pad in case of emergency. By holding the hook below the pad, you can rapidly remove the pad.|
|Breath Deflector It is a fog preventing factor for the helmets that don’t have pinlock. Another benefit of it is that if you lift the visor while moving, the wind won’t make breathing more difficult.|
|Glasses Groove This means you can use glasses with this helmet.|
|Internal Sun Visor It is the black visor on the helmets that looks like sunglasses and they are provided with UV filters. They can be opened or closed. You can think of it as wearing sunglasses.|
|Speaker Pockets Intercom is a device that connects via Bluetooth. Intercom dock is where the earphones of this device are placed. By connecting your intercom device with your phone, you can make a phone call, listen to music or connect with other intercom devices while driving. You don’t need to wear an additional earphone or another device.|
|Chin Curtain It is one of the features that affect both isolation and comfort, since the helmets usually get wind from below.|
|Spesific Feature/s If “READ THE DESCRIPTION” is written below the specifications, it means that there is a specific situation about the helmet. It is recommended for you to visit the specific page of the helmet and read what is written under the “OVERVIEW” tab.|
|Noise Inside The helmet's ability to reduce noise, to minimise the wind resistance and to encourage ventilation inside the helmet was assessed in a wind tunnel at a simulated riding speed of 100 km/h. The helmet was fitted on a mannequin designed for acoustic measurement. The mannequin was equipped with a specially designed microphone placed inside one of the mannequin's pinnas (ears). The wind resistance was measured using the force plate which is part of the wind tunnel and the ventilation was measured by measuring the pressure drop on the face and crown areas of the mannequin.||97.3dBA / 100km/h|
|Ventilation||9.1 over 17.5|
|Aerodynamics||7.5 over 10|
|Vertical Field of View||7.5 over 7.5|
