This attachment, this adapter, is an (admittedly, much needed) accessory. It is the missing link between your AGV motorcycle helmet and the SENA ARK intercom module.
This is how it works: the SENA ARK is a version of the 10S intercom. Top quality. Both the helmet and the intercom.
In order to keep them both at their best, good - and above all correct - mounting is required. A mounting that can link a (always the same, fixed) intercom module to a (variable) helmet shell.
Why a variable helmet shell?
AGV manufactures compact, sleek motorcycle helmets, with almost every helmet size having its own helmet shell. For some helmet types there are four. Each with its own curvature, each with its own length, each with its own dimensions. And thus: each with its own adapter.
Hence, depending on your AGV helmet and its size, you will need to choose the right intercom adapter to which you can then attach the (always right and always correct) SENA ARK.
Intercom adapter suitable for the AGV K5S helmet sizes ML-L-XL-XXL.
