Shuberth C4 pro

[Drabslab]

Does anyone have this helmet?

I just bought one and the first ride I experienced a terrible noise. Like a steam kettle from 90 km/h onwards.

Anybody with the same experience?

@Drabslab i can’t help with the C4, but I have a C3 Pro and I find it very quiet.

@Nick-Carthew problem solved (sort of).

The C4 pro has a big opening on top for ventilation and this is creatign a heap of turbulence leadign to a steam cettle noise. A piece of tape covering that opening is enough to make it stop. Now I need to find a more eye pleasing solution

@Drabslab Could you take the lining out and seal the vent from the inside?

[Drabslab]

@Nick-Carthew that is an option but with consequence of loosing the ventilation ... which can be very useful in the south of France

I am experimenting with small pieces of foam that let some air through, but prevent the wind from making turbulence

Just to come back to this issue.

This whole helmet purchase (two helmets, two SC1 advanced) is becoming a real frustration.

Just as a warning to fellow motorcyclists:

Don't let the reputation of the brand fool you:

The helmet is noisy, the ventilation on top catches turbulent air and whistles as a steam cettle

The SENA communication system is a letdown:

• complicated to use, for setting it up you must use combinations of pushes on tiny buttons (try to remember them all)
• virtually impossible to use with gloves
• user manual should get a reward for explaining the most simple things a complex as possible

If onlythis stuff would not be so expensive, I could throw it away
