iainc, I’d send that helmet back because it must be a forgery, given it is currently November 2016. How can a 2017 helmet possibly be in existence without time travel? 😉
I think my Met Testagrossa was coming up to 4 years old, when I had my RTA at the end of 2013, the bit of my head it protected came out far better than the bit that wasn’t!
I replaced it with a Bell Alchera around Easter 2014 and must admit, the thought of looking out for a replacement in the next few months or so had crossed my mind. I guess part of that is because Met is one of the few manufacturers that exceed the basic EU helmet standards, they use “Snell” IIRC.
