Selling my 2010 YZ450F, I've had this bike for several years and put most of the total hours on it. This bike has been great to me, is much improved from stock, and has been well taken care of. It's not a pristine low hour bike, but everything is well sorted and regularly maintained. Bike has a handful of carefully chosen upgrades. The engine is completely stock except for the titanium FMF exhaust, and it got a new OE piston about 25 hours ago. Added the Pro Circuit link and Dr. D engine relocation kit, which transform the handling of these bikes, it is easily the best handling bike I've owned after those improvements. It has a Galfer big brake kit up front with a braided steel line, and Sunline collapsable levers. Drivetrain is an Ironman sprocket, with a new renthal chain and new OE front sprocket. Also has a CF skid plate, turner footpegs, sunline brake pedal and hammerhead shifter. Bike has about 130 hours on it now, running strong with no leaks from anywhere. Lots of extras, stock pipe, a bunch of filters, etc.
