Foldable helmets for bikers who ride expensive motorcycles provide protection better than other low-cost competitor helmets.
The design of folding helmets allows the biker to fold the lower part of the helmet right towards the upper part for easy packing and storage.
Germany's Motorrad magazine has tested 12 different types of folding helmets priced between $163 and $763, according to the German news agency (DPA).
The Schuberth C4 helmet, which is for $763 as a starting price, comes in first place, beating the BMW 7 Carbon helmet which costs $646.
The lowest-priced model among these helmets came in last place and was viewed by some as an acceptable helmet that does its job.
At the same time, all the helmets tested have been shown to provide minimum security and safety requirements.
