Change over to rollers was mid 2012 so you're in the clear. 2014 was, I believe, the last year before the engine adopted the Cali 14 sump which means it will still have the spacer between the sump and block with the potentially problematic gasket. Swingarm bearings and shock linkage will need greasing for longevity as with all CARC machines. Wheels are spoked and tubeless. Weight is whatever it sez in the spec sheet, I have no idea. I do know that by contemporary standards they are heavy but they carry their weight well.
Inspect the throttlebodies closely, especially the throttlestop screw on the LH TB, for evidence of tampering.
Make sure it comes with two working factory keys or that you get the owner's user code prior to purchase.
