Ok i currently have an '04 YZ450 that has the 4 gear ratio in it. I am wondering if the newer model 450's are easier to ride on tight trails because of the 5 gear ratio? I was told by one person that the years in '03 and '04 when they made the YZ450's with the 4 gear ratios they were insanely powerful and hard to ride in the woods? Which mine is about impossible to ride in any kind of tight woods riding. I love the power of it and the get up and go in the open stuff but in the tight woods stuff i may as well be getting off and just pushing it as i can't ride it. My question is are the newer models easier to ride in tight woods stuff or would i be better off just looking at the WR450? Only problem i've read about the WR's is it sounds like u have to do a whole lot of work to them, removing stuff to make them run good and add a bunch of stuff to them? I just dont wanna go drop $7,000 on a new bike and be upset because i made the wrong choice.
