With Yamaha’s two-strokes featuring all-new aluminum frames in ’05, it was only expected that the four-strokes would follow suit. It appears Yamaha has made some changes to the frame, however. The YZ250F’s doesn’t feature the same hollow cut-outs as the ’05 two-strokes.What other changes can you expect for 2006?
