Well I am BRAND new to the forum. Wealth of knowledge here, thanks so much to everyone who contributes...its great. Well here is my problem. And I know I will probably get bashed a little, but its okay...I actually probably deserve it. I just got an 06 YZ450F. Sadly enough its got literally an hour on it. You guys knows what coming right??? This crazy thing is too much for me!!! Big surprise right? So I need to find something that I can actually enjoy riding the track on instead of hanging on for dear life. Okay, two things that I think are getting to me on the 450. First, i am vertically challenged, so the seat height thing makes me less confident I think. Second, believe it or not, POWER!! I am thinking its got too freakin much for me (can't believe I am actually saying that, but its either admit it or get more medical insurance). I am thinking I should be on a 250F. I would say my skill level is not beginner, but maybe intermediate. So here is my question. What would you say about the power difference (feel) between the 450 and 250? Say mayabe 60 percent, 75 percent? I was hoping someone could give me a good description/comparison between the two. Any advise from you more experienced folks? Oh and I know the height thing won't be much different, but I think I am going to have to modify it either way. I am just thinking the combination of too much power and too much height are the sum of my problem. Thanks so much for any help. Regards.
