I bought my SH KX500AF back in late 2009 brand new from SH. Brand new 2008 KX450F frame. I included a Clarke 3.2 tank and a E-line carbon fiber pipe guard with the purchase. I paid just under 12K which included shipping to Nevada. 19K for a new one! It's been six years almost seven since I bought mine but that still seems to be a huge price jump! Wow! Hopefully that means mine is holding it's value better. Down side for me on the new one's beside price would be air forks. Not a believer in them yet.
