Bought a Shoei RF-SR last summer and it’s mostly comfortable except for the forehead, which is too tight and doesn’t feel good when I ride. Turns out I’m probably a better candidate for an Arai helmet given my head shape. The Shoei has about 900 miles on it total and is still in great condition. I’ve tried a thinner internal cushion but it hasn’t helped much. Is there any way to safely remove some of the harder foam in the forehead area or is this going to degrade the safety of the helmet and/or be uncomfortable in its own way? Should I try this or am I better off selling the helmet used and getting a new Arai?
