My guess is that it will be the new YZF 450 motor in a new quad frame for MX and the sort since they don't really have anything out there for that, although I have seen some sick MX Banshees. When these motors hit the bikes they maintaned the YZ and CR designation but with an added F indicating the 4 stroke motor. Of course everyone knows this, but since the 450 will purely be a high performance machine, they gave it the same YFZ designation as the Banshee. This will be a great machine and if Honda really wanted to make a dent in the hi pro world, they would step to as to gettin that CRF 450 in a quad. I don't see us getting any more two strokes.
