The ventilation system effectively takes 

outer air in and pushes the inner humid 

air out by the air pressure from the front 

while riding. The ventilations are 

equipped with a shutter which prevents 

cold air and water drops from coming 

into your helmet.

The Wake Stabilizer PATENTED , KABUTO’s 

unique system, is developed by analyzing the 

results of wind tunnel experiments at several 

angles. This unique system controls the airflow 

around the helmet and reduces loads while 

riding.

WARNING!

●

Operating the shutter while riding is very dangerous. Never operate the 

shutter while riding. Operate it before riding. 

●

The air-ducts (air intakes and discharge holes) of the head ventilations and 

the rear ventilation are designed in the proper sizes and quantities 

considered a large impact in the event of accidents and falling down. 

Customizing by enlarging or making more air-ducts would reduce the safety 

performances significantly and can cause serious injuries in case of an 

accident. Never customize your helmet.

CAUTION

●The shield is so constructed that it cannot 

be removed unless it is moved up to the 

highest position.

●Do not pull or twist the shield by force to 

remove it. Such action may damage the 

shield and ratchet system.

●●Handle the removed shield with care in 

order not to damage it.

Repairing the ventilations

When each ventilation is damaged, contact your local authorized Kabuto 

dealer. (See Pages 23 to 25).

Please be informed that we may not accept repairing, in the case the safety 

performance of the helmet will be degraded.

●The interiors of this helmet are washable by a washing machine. Put each pad in a washing 

net and wash them separately.

●Use detergent in cold water or warm water for cleaning. Never use hot water, chemical 

detergents, and organic solvents for cleaning the pads. The use of these agents may degrade 

the quality and damage the pads.

●Even commercially-available detergent may cause a little discolouration of the pad depending 

on the type of detergent. Thus, please wash each pad separately as much as practical.

●If the pad is washed in a washing machine having a drying function in which the temperature is 

increased to 50ºC or more, it may cause deterioration in quality and damage of the pads.

Do not use such a device for cleaning of the pad.

●Drain a pad after washing and dry the pad in shade so that it is not exposed to direct sunlight. 

After making sure that it is dried enough, attach it on the helmet.

●The inner pad and the cheek pad are consumable items. Even under normal usage, the fabric 

material and inner foam may be worn and deteriorated depending on the frequency of usage. 

Please replace the pads with new ones as appropriate.

NOTES BEFORE USE

Thank you very much for purchasing a KABUTO helmet.

This Instruction Manual describes proper handling, various functions and 

remove/replace each part of this helmet. Please read this Instruction Manual 

thoroughly prior to use.

After reading this, keep this Manual for future reference.

The helmet is just one element of protection, it is intended to minimize the risk 

in the event of an accident. It cannot ensure complete safety. 

Use this helmet properly based on this understanding.

Please understand and follow the instructions and information in this 

Instruction Manual to enjoy your safe ride. 

It is very dangerous to wear a too large sized helmet. This may wobble while riding. If you wear a 

too small size helmet, it tightens up and hurts your head. Thus, it is important to select the proper 

size.

The helmet is designed to be retained by straps under the chin. In order to assure proper 

protection, the helmet should fit your head. When worn, adjust it to rest properly on the head, 

securely fasten the chinstraps to ensure safety. The chinstraps prevent the helmet from coming off 

in most cases. 

In order to fully maintain the performance of this helmet, do not attempt to take apart or change the 

helmet in any manner such as making holes in it or cutting it.

Liners are essential for the intended performance of the helmet. 

This helmet has been designed to absorb the impact energy when components as shell and liners 

are partially destroyed by an impact.

Even if visually no damage is apparent, it could be seriously damaged by a small impact. 

Regardless of the degree of damage, the helmet that underwent an impact or was abused even 

only once should not be used anymore. 

Always handle the helmet with care and make sure that no one sits on it or drops it.

Never use the helmet once impacted

Clean the helmet with soft cloth, using common ph-neutral detergent diluted with clear water. The 

cloth should not be soaking wet. Then wipe the helmet gently with a clean wet soft cloth and leave 

it to dry completely, but not in direct sunlight. 

With regard to helmets with removable interiors, carefully read the instruction manual for that 

model before attempting to remove the interiors and carry out cleaning according to the 

explanation provided. To clean the helmet do not use saline water or hot water (above 50ºC).

Never modify the helmet

Select the proper size!

The storage of the helmet

Shield care and cleaning

Notes for use of full-face helmet

After using the helmet, stow it away in the helmet bag and store on a level place such as a shelf; 

the helmet may be damaged if it rolls around or falls down.

Do not leave the helmet in direct heat above 50ºC e.g. next to a heater or under direct sunlight in a 

car.

Cautions for shield

If the visor is marked “Day Time Use Only”, visibility is limited to daylight conditions and it is not 

suitable for use at night. 

Tinted lenses are not suitable for use at night. 

A visor and goggles with scratches lowers the visibility and this is very dangerous. Such visors 

should never be used at night and should be replaced. 

Contact with petroleum products and other solvents may impair the optical properties and weaken 

the strength of the visor. 

Never try to open or close nor remove the visor while riding.

After using your helmet, with a wet soft cloth, lightly wipe off any grime (e.g. dead insects, dirt, 

sand, dust, etc.) on the shield and then fully wipe it clean using a dry soft cloth. When the shield 

gets wet (e.g. rainwater), it should always be wiped with a soft cloth after use.

When cleaning the shield, never use any petroleum-based solvents or detergents containing 

abrasives.

Contact with petroleum products and other solvents may impair the optical properties and reduce 

the mechanical strength.

To clean the shield, apply some common ph-neutral detergent diluted with clear water using a soft 

cloth and wipe gently. Finally, wipe it dry with a lint-free soft cloth. To clean the shield, do not use 

saline water or hot water (above 50ºC).

When you wear a full-face helmet, the temperature in the helmet is maintained nearly constant 

while riding but the surroundings are constantly changing since you are moving at a high speed.

For this reason, in case of sudden rain, entering a tunnel or in a place with a large height 

difference, the shield can be fogged suddenly because of the difference in temperature 

in-and-outside the helmet.

In case such a risk is expected, please use caution with adjusting the shield or slowing down your 

speed in advance.

Never open or close the shield nor adjust the ventilation shutter while riding since it is very 

dangerous. Adjust the shield before riding.

Any paint, glue, adhesive stickers, etc. (or the use of detergents and solvents other than those 

prescribed) may not only reduce the original protective performance of the helmet considerably, 

but may also cause damage to the helmet that cannot be detected by the naked eye.

Do not paint or apply solvent

Handle your helmet with care

Do not toss your helmet over a floor or sit on it. The helmet absorbs an impact every time it is 

handled roughly and its impact-absorbing capacity will be decreased. Handle your helmet with 

care to assure its full intended function in the event of an accident.

Do not use your helmet for any purpose other than to use for protecting your head while riding.
