C. THE HELMET

1. STANDARD

The C4 PRO conforms to the ECE-R 22.05 standard. This testing norm guarantees conformity to dened safety standards in respect of impact absorption, visor, retention system and eld of vision. The certication applies to all the countries of the European Union and all countries that recognise the ECE standard. It also guarantees conformity with all insurance requirements that are important in the event of a claim.

Please note that this C4 PRO with ECE approval is not certied for the USA, Canada or any other EU countries. It is only permitted for use in countries where the ECE standard is valid.

Note:

The only SCHUBERTH helmets that it is legal to use in the USA, Canada or other non-EU countries are those with the appropriate approval and technical specications. Further information and details of sales outlets for these helmets can be found on the internet at:

4. OUTER SHELL

The outer shell of the C4 PRO helmet combines an aerodynamically optimal shape with consistent protection. It consists of a special glass-bre reinforced duroplastic matrix developed by SCHUBERTH, which gives the helmet the high level of strength needed for your protection.

Caution:

The safety helmet is designed to absorb the eects of only one impact. The helmet must be replaced after a fall, accident or any other impact.

5. INNER SHELL

For optimised impact absorption properties, the inner shell of the helmet consists of several components. The complex multi-segment foam padding of the main body provides better absorption and dissipation of impact forces and gives you the highest level of safety. The large side panels ensure the helmet sits optimally and comfortably.

6. AERODYNAMICS

Wind noise is low with the C4 PRO, both for race-riding and during long touring rides. The C4 PRO produces practically no uplift even at speed.

Note:

Please note that the strong eddy currents that can occur as a result of the fairing on faired motorcycles may have a signicant eect on the aerodynamic characteristics of a helmet.

7. AEROACOUSTICS

Various features developed in SCHUBERTH’s wind tunnel make the helmet notably quiet as far as aeroacoustics are concerned, while providing optimised hearing capability when riding. This enhances concentration, especially at high speeds.

Note:

Aeroacoustic values may vary according to the type of motorcycle, fairing design, seat position and physical size of the rider.

Caution:

As a result of the aeroacoustic optimisation of the helmet (and the lower wind noise inside the helmet that comes with it), your actual speed can easily be underestimated. Please do not rely on your sense of hearing to estimate your road speed - always check it using your speedometer.

Note:

With faired motorcycles, strong eddy currents occur at the edges of the wind shadow. These may signicantly reduce the aeroacoustic performance of the helmet. The motorcycle fairing should be adjusted so that the turbulence created does not reach the bottom surface of the helmet.

Turbulators

The patented turbulators on the top of the face shield also optimise the aeroacoustic properties when riding and prevent acoustic disturbances in the form of whistling sounds that can be created by smooth and straight edges.

C. THE HELMET

8. WIND DEFLECTOR

The wind deector prevents the unpleasant eect of the wind created as you ride owing into the helmet. In addition, the riding noise in the helmet is reduced.

The wind deector is attached by Velcro strips on the inside of the acoustic collar and can be removed when required to provide an additional ow of fresh air, especially in hot weather.

Tip:

The t of the bottom of the helmet is extremely important in ensuring that the helmet is as quiet as possible. If you have a smaller neck size, we recommend that you also wear a scarf.

9. CHIN BAR

The C4 PRO is equipped with a chin bar that pivots up and can be easily opened and closed by means of the operating element located in the middle of the chin bar. The movement of the section required for this is optimised for convenient, smooth operation.

OPERATION

The chin bar can be opened at any time irrespective of the position of the visor or sun visor. The sti, positive engagement at the end of travel ensures the chin bar remains safely in place when raised.

OPENING THE CHIN BAR

1. Open the chin bar by sliding the red button located in the middle of the chin zone forwards in the direction of the arrow as far as it will go, using your thumb.

2. The chin section ips right up.

CLOSING THE CHIN BAR

To close the chin bar, pivot it down with one hand until both locks audibly engage.

C. THE HELMET

Note:

Each time you close the chin bar, check that the locks have engaged properly by pressing the chin bar upwards.

Tip:

When using the additional adjustable wind deector, locking the chin bar is easier if you grip the chin pad underneath with a nger of your other hand to help you ease the chin bar over your chin.

Caution:

Never ride with the chin bar raised.

10. CHINSTRAP WITH MICRO-LOCK RATCHET FASTENERS

The C4 PRO is tted with a ratchet strap. This locking system is easy to use and enables you to adjust the chinstrap perfectly to your head every time you put the helmet on.

ADJUSTING THE CHINSTRAP

The length of the chinstrap is adjusted by increasing or reducing the length of strap pulled through the metal buckles. Adjust the length of the chinstrap so that it ts rmly but comfortably under your chin and x the end of the strap using the retaining loop with comfort pad.

Caution:

When adjusting the strap, make sure that the helmet cannot be pulled o in a forward direction with the chinstrap closed.

Caution:

Check the adjustment of the chinstrap length at regular intervals.

OPENING AND CLOSING

To close the chinstrap fastener, slide the ratchet tongue step by step into the locking buckle. If you nd that the chinstrap ts too loosely around your chin, slide the ratchet tongue one step further into the locking buckle. When adjusting the chinstrap, make sure that it rests rmly but not uncomfortably around your chin. To open the chinstrap, pull the red ribbon on the ratchet fastener upwards to release the locking buckle. Then pull the ratchet tongue out of the locking buckle.

Caution:

Never ride without making sure that the chinstrap is correctly fastened and adjusted and properly positioned. If the chinstrap is not correctly adjusted or fastened, the helmet could be displaced in the event of an accident.

Caution:

Never open the chinstrap while riding.

C. THE HELMET

11. VISOR WITH ANTI-FOG LENS

The visor is a fog-free double-lens visor. By xing the inner anti-fog lens using eccentric pins, the two visor panes are pre-tensioned together and are thereby sealed. An insulating air cushion is thus formed between the visor’s main plate – i.e. the outer plate – and the inner plate, which prevents any fogging up of the inner plate.

COATING

The main visor has an anti-scratch coating.

Note:

The helmet should never be used to hold gloves or any other objects as this may damage the scratch-sensitive anti-fog lens.

Note:

The anti-fog lens is supplied with a protective lm. Remove this lm before using the helmet for the rst time.

OPENING THE FACE SHIELD

To open the face shield, use your thumb to push the face shield up using one of the nger tabs situated to the left and right of the face shield, and move it to the desired position.

FACE SHIELD (INCLUDING URBAN POSITION)

The second position (urban position) locks in place more rmly, providing greater resistance when the face shield is in this position. This makes it easier to lock the face shield in the urban position, especially while riding.

• When you push the face shield open, it may well travel beyond the urban position

• but it is easy to nd this position by moving it downwards again. The face shield mechanism requires no additional lubrication. The face shield can be operated at any time irrespective of the position of the sun visor.

CLOSING THE FACE SHIELD

To close the face shield, grip the nger tabs at top left and right and press the face shield down with one movement until it audibly locks into place.

REPLACING THE VISOR SHIELD

Changing the face shield is easy to do without tools using the convenient EasyChange mechanism. To replace the face shield, it is helpful to place the helmet on a at surface or on your lap while seated.

Removing the face shield

1. Move the face shield into the uppermost locked position.
