Here’s another top tip from Nick Potter. There is a very small amount of sponge to the front of the head rest as bolted to the roll bar. Go and blag an off cut from your local carpet shop or as I got mine, a sample that was being sold for 50p as a ‘door mat’. Cut around the headrest with a Stanley knife, keeping about 0.5CM inside the square. Do this twice to make two pieces thus some 1CM smaller in width and length, then bind the two pieces of carpet to the headrest with some electrical insulation tape. This simple top tip will help reduce the bumping of your helmet against the headrest.
