5 years guarantee on a Shark motorcycle helmet but no one want to take it, the shop were I buy it is close... Even Honda Bigwing refuse to take care of the guarantee...

Anonymous. FYI Here are your exclusions so you don't go chasing rainbows.

This warranty only covers problems related to materials or manufacturing. SHARK cannot be held liable with regard to the product in the following cases:

Any damage following:
1) a fall or accident
2) a technical modification made by the user or a third party (glue, adhesives, paint, screws, etc.)
3) use of or contact with: harmful chemical products (including methylated spirits on the visor treatments), or an intense heat source
4) incorrect use: abnormal conditions (e.g. underwater), lack of maintenance or care
5) ageing due to normal wear of the inner fabrics or foams, the appearance of the external parts, or the visor (scratches, marks, etc.)
6) abnormal and prolonged exposure to ultra-violet light, in particular for the decorative colours.

In addition, SHARK cannot consider subjective considerations related to use of the helmet as defects covered by the warranty: problems with comfort, size, noise or whistling, aerodynamics, etc.
SHARK cannot be held liable for the temporary non-availability of the helmet while it is being enhanced to satisfy the needs of its owner.
In all cases, the maximum warranty period is 5 years. Replacement of a component during this period does not prolong this period.

If it is something simply likely they will send you the parts from France.
