I have owned both.07 450 and now 07 660 Yes, in certain conditions the 420 will do whatever the 660 will. I put 440 trouble free miles on the 450 in six months with no problems. But on the occasion my buddy and I would get on a straight................his 660 would reel me in. For me, I knew I had made a mistake when I bought the 450 ,so six-months later at about a 2500 dollar loss, I got rid of it and got the 660 . If you are the least-bit performance minded-get the 660 or 700.

I agree the trails is were it will shine the wide open areas not so much, it depends on your terrain, like I said dunes definetly 660, and actually I would go with the 700, I have the grizzly 700 and it's an awesome motor, I feel that this new 700 is a very reliable engine!

10-4, if trails are ALL you are going to do the 450's fine, but like I said, if your eyes gleam at the thought of L/T , pipes,mods, ect-DONT DO IT!!!!! 07 660's can be had for the MSRP of a 450, well, depends on the dealer of course!!.
