All these parts are OEM, unless otherwise stated, not cheap Chinese knock-offs. This was a good strong running bike. This is the swingarm OEM.
In good shape as images show, the bearings are tight, not rust seized, the chain adjusting bolts work good, needs a new chain slide, there is a little wear as can be seen in the last image, ready to bolt on and go. Will fit 2009 2010 and other years, models, and some parts will fit 250f's, but do your homework or confirm with a dealer first. Comes with all you see.
