My first DS brain-bucket was a GMax GM11D Dual Sport full face helmet. It’s a XXL to fit my 8″ head and it fit well, right up to that 60MPH headwind that when combined with the windspeed of freeway driving, drills anything through your skull. And that’s usually after eight hours of continuous riding. I’ve never had a helmet that I couldn’t get out of fast enough after long stretches.
Despite its huge visor, it’s been engineered to handle freeway speed winds rather well. I don’t ride with an elevated wind screen so I’m getting blasted at anything over 70MPH, but this helmet holds its own. Until a crosswind. Then a twist-top BudLight in the hands of a thirsty Harley rider has a better chance of not twisting around than my head does.
