Looks like we going to get totally new 450 2014. I saw picture and some details. Hard to belive but it will be 400cc engine 250f frame or least its look like that. Complety new EFI this i dont know how it is but something totally new what we not seen mx bikes yet. And engine is turn back normal way. Air forks. Public release for details new bike will be july bikes arrive shops around end august early septemper. Rumor is that yamaha makes really big effort to marketing this new bike least in europe. We just need wait and see.
