Hey guys my local dealer has a left over 05 YZ450 he will sell me for $5,880 out the door. I have a 98 WR 400 now and ride woods but would really like to get a 450 . Are there some wood's guys that have one? How does the 4 speed gear box work for you and did you change the front sprocket to make it work better in tight woods ? Do you have any trouble with it stalling ? Have you added a fly wheel weight and what was it? I aim 48 and I have been riding off road for about 30 years or so. I don't race, just play ride .
