Hi, too late you bought it. Your Nolan is made from polycarbonate, it will need to be replaced in a couple of years because it becomes weeker over time, UV rays and the like. It also weighs more than most shells, which in the case of an accident can increase the risk of neck injury. Not even ACU approved.
I think you should have gone for a composite shell like the Shoei Raid II everyone was recommending to you. I paid £150 for mine, it came top of Ride magazines helmets test. To my mind less is more - less features = more protection. Composite helmets also last 5 years.
If you do the maths Nolan = £90 per year & Shoei = £30 per year.
Why did you ask for advice then ingore it
. And why a flip front - this is an SV site not BMW? I don't mean to come down on you, your money, your choice, your life. Don't become a statistic.
