I've had a problem with riding for more than about an hour because I get a crick in my neck from straining against the force of the wind beating against my fullface helmet. Bought a "661" foam race collar and rode for over 2 hours today without as much as a twinge from my neck! It fills the gap between the bottom back of my helmet and the base of my neck which supports the helmet against the wind so my neck was relaxed the whole time. It's a dirt bike gear item that only cost me $40. Anyone else doing this?? Here's a link http://www.sixsixone.com/Catalog....83f6ad. It's the "Neck Roll" towards the bottom of the page.
