Oh yes, a black motorcycle helmet is a nice proof...
Have you ever been to any motorcycle event? Have you counted the guys wearing a Valentino Rossi helmet??

Look up Patrik Fürstenhoff on Facebook. Then compare it to the guy at 2:15 in this video:

It's well known by now that it is Patrik. It's the same dude I met before, and most of the places where his videos are recorded I happen to know pretty damn well. Considering where he lives it makes total sense. Most of the racing he's been doing has either been done in stockholm which is about 15 minutes away from where he lives or around the suburbs which he lives/lived in.
Besides the helmet we looked at his personal GhostRider dvd collection, with a ton of stuff in it that never was for sale.
