I cant remember who it was a year or so ago who raced the open pro class at Mammoth Mtn on a KX500 and placed 2nd or 3rd,but this year I just found Scott Sheak finished 3rd in the Open Pro at Mammoth on a KX500.It just goes to show the 500 isnt just the best at Desert but can still Moto.It makes me wonder if the open class wasnt dead and Kawasaki put a little R&D into it how fast the big KX would be?It shure says a lot for the origanal K5.
