What was it about the introduction of the YZ400 a few years back that made you put aside the 2-strokes and hop on the 4 banger. Was it the rumours of Doug Dubach putting in 4 second per lap faster times at the test tracks? Was it the rave reviews MXA gave the YZ? Was it the night Doug Henry won the Las Vegas SX in its' very first race? Was it time for something new and a change in scenery? For me the YZ 4-strokes just have something about them that is so cool yet the bikes are so good. What's your take?
