If that new airbox is internally channeled like I think it is, the filter will be more isolated from splash water entering the top than a traditional airbox. Its also easy to see how they would get a large still air volume on the clean side.
This is how I think its setup. Please excuse my crude drawing, but you will get the idea.
Clay,
Will you be loaning a 2012 XC300 to the major bike magazines to test?
I don't care what any magazine, especially a big west coast mag driven by advertising dollars, says. K&N type gauze filter is a bad deal for a dirt bike. Its even a bad deal for a sport bike unless it lives on the track(clean). Been there, done that. Drawn my own conclusions that are backed up by many, using science not ad $$. I suspect GG knows this as well, hence the noted use of a foam filter. If by chance they do come with a gauze filter I can guarantee that mine will never be ridden with it.
When will we see pictures and specs on the actual bike that will be coming to the states?
