A new helmet! A new setup! A new feel!
The new Shoei GT Air Exposure helmet comes with a free little bottle of silicone oil. The Shoei guide says you should lubricate the rubber gasket around the seal of the visor. This is to stop it drying out and the rubber splitting. Apparently you should lube it regularly; you only need a tiny smear on the perimeter. Here I show you how I applied the oil to my helmet using a cotton bud.
