Alpinestars Supertech SM5 Speed Motocross Helmet in the Black Yellow Fluo Light Blue design - Alpinestars Motocross Enduro Helmets
The all-new Alpinestars SM5 helmet is the result of more than five years of intensive study, development and testing. We scrutinized every possible aspect to engineer a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort.
This lightweight SM5 helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and lightweight, while the five density EPS liner ensures the correct density in the correct area for enhanced impact absorption.Other key design features include an engineered raised area with padding to effectively reduce the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
