+1 on the Scorp..I bought one towards winter and rode in it doing everything I could think of to fog it up and it never happened! I love my Shoei RF1000 helmet but it fogs instantly...I was amazed at how the Scorp. didn't. I would have kept it but the wind noise was over the top....

 

My Scorpion rarely fogs up. And when it does, it is only partial, right in front of my nose and only at slow speeds.

The key, I always though, was the correct kind of ventilation. Scorpions have a good vent system to keep air going along the inside of the visor and not directly in your eyes.

I have an Arai that fogs instantly.

 

My Shoei RF1000 came with a removable breath/fog guard. Works great.

 

When you breath try to direct your breath down thru the bottom of your helmet. Also when you are stopped crack the shield open some to get some air circulating.

 

My FF has a pinlock permanently fitted, had the visor round the pinlock fog up a bit but never the pinlock itself. I never really notice the pinlock in my vision until the fogging around it occurs so it is not intrusive.

 

+1 for the pinlock...... actually just reminded me that I need a new pinlock insert for my rf-1000. Old one scratched when I wasn't careful cleaning it.... didn't notice the big metal shaving clinging to my rag.

That thing took me through more than a few rain storms and never fogged

 

I bought one for my Nolan and it works GREAT!!!!!

Highly recommend!!!

 

Another thing to keep in mind is when you take your full face helmet off and rest it on your seat for a second make sure the shield faces to the right. If the helmet falls the brand new (still has that new smell) shield will not get scratched.
