Right now i ride an 02 ttr225. The suspension is in bad shape, especially the front forks, and i just want something nicer all around. I found an 04 wr450 that i like, but im not sure if it would be good in the type of riding i do. The ttr is good in my type of riding, but the suspension is horrible and i want more power. Im riding the little ttr waaay harder than its meant for I ride on mostly slow to moderate speed trails, with some relatively fast parts. There are rocky areas, mud, and just about everythign in between. Sometimes i like to just turn off the trail and go wherever i desire out in the woods, which most of the time means frequent stops, very slow speed, and backing up. The ttr is 260lbs and the wr is 245lbs, but the wr's seat height is 5 inches higher than the ttr. I'm not a small guy, i'm 6'2 and 175lbs. I work out HARD 5 times a week and have been lifting for years, so i'm not weak. I know i can manage the weight of the big WR because i manage the heavier ttr easily, but the height is what concerns me. I keep hearing that i should get a 250 for trails/woods, but i want to buy a bike that will last me for many years, not something i'll have to sell when i get power hungry again. Also, the reliability of the WR's seems rock solid as far as my research goes, am i missing something? Thanks in advance for any replies, i'll add any more questions as i think of them.
