Well i've had my Scorpion Exo-900 for almost 2 years and have been eyeing the Nolan N90 for awhile but was happy with the Scorpion but after the crash and the Scorpion got road rash decided to get the Nolan. So my girl got it for me as one of my christmas gifts. So took out both helmets and put side to side. First impressions are the Nolan is smaller & lighter than the Scorpion and the Nolan fits so much better to my shape of head the Nolan fits like the Shoei Multi-Tech i had tried on very comfy. So first impressions i think i'm going to like the Nolan more but will know more once i take it out for a litle ride. Love the helmets latching system.
