Deals of this magnitude are not hatched over night and I suspect that Yamaha was involved at many levels, financially as well, with the development of the Yamacat chassis as the seemingly rapid adjustment to installing the Yamaha 3 cylinder engine would not be possible.
Arctic Cat has known for some time that their Suzuki collaberation was coming to an end. Just imagine if they announced two years ago that in 2014 cat would be running Yamaha engines...who would have purchased a 2012 or 2013 Cat?
There is always more to deals like this then initially meets the eye...maybe this chassis Arctic was using never was an Arctic Cat chassis...but a Yamaha in Cats clothes all along!!!
I am beginning to think this is what has actually occured.
