Warm Tips: You can choose correct size base on below size chart

Shell Size
Main Characteristics Compact & Lightweight

Light and Small, an ideal shape of a helmet is realized

Compactness, one of Z series concepts, is realized in a lively aero shape.
Shells are in 4 sizes adding exclusive shell helmet sizes to make these smaller.
And also, every component is made lighter to achieve ultimate light weight as sports full-face. All of these realized an ideal compactness and light weight.
Aero Shape

Refined Aero Shape realizing both Design and Performance

High Speed Riding splitting an Air.
Together with a rider and a motorcycle, a helmet also attacks a wall of air.
Aerodynamics of a helmet affects directly a load on neck of a rider especially in high speed riding.
SHOEI improved aero shape firmer and more practical by repeating tests in large wind tunnel facility.

Aerodynamics of Z-7

Compared with Z-6, DRAG and LIFT are improved by 5 x and 1 x respectively.
x Values are measured in in-house wind tunnel experiment facility.
Quietness

Quietness = Comfort experienced especially in Long Riding

A load on a rider in long time high speed riding is not only a wind pressure. A wind noise invading into a helmet disturbs riders concentration and causes fatigue when it continues long time.
Aero shape and airtight shield system minimize occurrence of wind noise itself and airtight interiors block invasion of noise. And also, equipping removable ear pad in ear space of a helmet realized substantial decrease of wind noise.
Double and triple devices against occurrence and invasion of noise restrain riders fatigue in long time riding substantially.

Independent lips of window beading in upper and side portions made it more elastic and improved close contact with a shield. An improved air tightness avoids occurance of wind noise caused by invasion of air.

Removable ear pad is equipped in ear space to avoid invasion of wind noise. Plastic plate in ear space puching processed to avoid echo of noise inside.

Comparison of Wind Noise under Circumstance equivalent to Rinding as 100km/h

Compared with Z-6, wind noise is restrained more in all frequency ranges in Z-7.
x Values are measured in in-house wind tunnel experiment facility.
Shield System

Newly Developed CWR-1 Shield

Ribs on top and bottom in the same height as thickness of PINLOCK® fog-free sheet enhance its close contact with a shield and improve rigidity of a shiled.

CWR-1 Shield which secures Natural and Clear Vision

Newly developed CWR-1 Shield provides you with natural and clear vision with improved optical characteristics and minimum distortion realized by applying best and different radius and thickness in each area of a shield. And also, ribs on top and bottom of a shield improve rigidity of a shield and eliminate bending of a shield by wind pressure and twisting in opening or closing. High quality is realized also in airtightness in high speed riding and easy handling of opening and closing.

Further Advanced Shield Opening and Closing System

A shield system securing easy and firm fixing and removing as well as high airtightness in variable axis double action mechanism was also renovated in every aspect in Z-7.
Review of a spring ratio of shield base largely improved smoothness of opening and closing as well as airtightness in fully closed position. When a shield is fully closed, a hook located in rear side of shield nob is locked to a shell and avoids unexpected opening or motions of a shield by wind pressure maintaining high airtightness.

A shield lock mechanism is equipped in a nob in bottom of a sheild and hold a shield firmly when it is fully closed.

Shield base slides fore and rear in 5 steps by rotating a dial. Airtightness of a shiled can be fine adjusted in both sides by maximum 1mm.
Interiors

Comfortable fitting and firm hold realize high quality riding

Comfortable fitting, essential to comfortable riding, is secured by interior system which is newly adopted in Z-7.
A shape or rigidity of bottom of shell may affect may affects tight feeling when wearing or removing a helmet. A cheek pad integrated with distinctive cut line in shell side softened tight feeling in wearing and removing, and improved easiness of motions around neck for rear checking. And also, 3D shaped polyurethane foam pad realized a cheek pad in high volume at the bottom which supports cheek softly and, at the same time, avoids invasion of wind or noise.
3D Full Support Inner Type IV is applied to center pad. While soft napping material is applied to an area which touches a skin in wearing or removing, high moisture absorptive advanced material is applied to an area where effective absorption of sweat is expected while wearing. It realized both soft fitting and comfortable wearing. And also, red mesh material is used partially as an accent to express sporty impression by grey and red colors.

For part which will be affected friction damage consists of raised fiber. For part of necessity to absorb sweat consist of highly moisture absorptive nylon.

Distinctive cut line eases wearing and removing and softens tight feeling.
Ventilation System

The more you ride, the more you feel wind and coolness

Air intakes are placed in a center of forehead and both sides and riding wind is lead straight to inside of liner realizing high ventilation performance where a rider may feel wind even inside a helmet. Air outlets with spoiler performance stabilize a helmet in high speed riding and exhaust hot air effectively through 4 outlet holes.
E.Q.R.S.

It is very difficult for a third party to remove a helmet from a rider in an accident.
Exclusive tab is equipped to cheek pad of Z-7.
By pulling this tab, a relief party may remove a cheek pad and remove a helmet easily without hold on a cheek.

x When removing cheek pads for a usual maintenance, do not use E.Q.R.S. tabs.
