So a member on here have a 2008 LE YZ450F. He stated that it only has 12 hours on it. He wants to trade for my 2009 ME KX250F. I bike has about the same amount of time on it. I just paid 6k for bike last month but I am feeling like I am going to want a 450 very soon. So, should I trade now or wait it out and sell my bike next year and get a 450, it does seem like these this skydive in price after you use them. Also EFI means nothing to me, 5 out of the top 10 bikes in ever race seem to be Yami's with no EFI. Please help me out, my brain is killing me from thinking about this so much.
