Description

The masters of MX protection have crafted the SM5 MX Helmet: Alpinestars have questioned and re-built every aspect of what makes a fantastic motocross helmet. The SM5 comes with a price point that is accessible to all. What you get is one of the lightest mx helmets available. A polymer blend shell with varying degrees of thickness is engineered to deliver the optimal combination of impact protection and light weight. Due to the brand's understanding of all other aspects of motocross gear, the Alpinestars team engineered a raised area with padding to reduce the forces transmitted to the collarbone in case of a crash. And, cool are not just the graphics, the whole structure is ultra-ventilated for a cooler head! Verdict: It does not get much better than this!

Alpinestars Motocross Helmets Size Guide


It is easy to find the helmet size to fit you. Motorcycle helmets should fit snugly on your head even if you have got big hair. Ideally pressure should feel firm and even all over.
Where to Measure To find the right helmet size, measure all the way around your head at the widest part from the front of your forehead right around the back of your head and back to the front again, keep the tape measure above your ears as shown (F) and make sure it feels firm but not overtight or too loose - all measurements in centimetres (CMs).
