Im looking at buying a bike which I will hopefully be able to keep for the next 5 plus years. I have it narrowed down to 3 choices and am looking for input on comparables. My main questions is comparing the 05' 250 to the 04 450'. I would love to have the aluminum framed bike, but is the 05' 250 better is enough ways to justify the 1,000 dollar price difference? For some reason the 05' seems way newer than the 04', even though its only a year difference. I just graduated form college and will be starting a new job tht doesnt pay alot. Im looking to buy a bike with some savings I have and will be looking for a bike I can ride for the long term... Any thoughts? 1. 2006 YZ450F: Overall condition is 9/10. Has full white brothers pipe and asv levers. 1 Owner bike. Price is $2,400. 2. 2004 YZ450F: Bike looks pretty rough in terms of plastics, seat cover, and graphics.Looks probably 6/10. All of this I would replace ASAP. Bike Runs excellent and appears to be mechanically maintained very well.Runs 10/10. Bike has port and polished head, new pistion and rings, full white bro's carbon pipe, revalved suspension, and brand new tires. Bike pulls hard from my test ride. Price is $1,500. 3. 2005 YZ250. Bike looks 8/10. Will just need some new graphics. Bike is pretty clean, but does show some use. Has pull pro circut exhaust. Tires are 8/10. Runs very well and has great compression. Seems to be jetter right on. Price is currently 2,500 with owner maybe willing to come down a few hundred.
