4. SAFETY ADVICE CONCERNING MODIFICATIONS/
ACCESSORIES
Never modify your helmet. Original components (in particular on the outer
shell, inner shell and restraint system) should not be altered or removed.
The fitting of additional parts from other manufacturers that have not
been recommended can reduce the protective effect and renders the DOT
FMVSS No. 218 Standard. and all warranty and insurance claims invalid.
Use only original parts, replacement parts and accessories that
SCHUBERTH has expressly approved for your helmet!
Use of an unapproved visor will void the helmet approval.
