I wouldn't be afraid of 1K of track miles on an 1199. Frankly probably was good for the bike as many of these simply don't get ridden hard enough to break in fully. Given the performance level it is tough to do this on the street. The oversquare bore and low tension ring setup means you really need to load the motor to break it in. If Chad at Commonwealth has tuned the bike, it should be a strong example. If not you should see if the seller will agree to make the sale contingent on how the bike does on the dyno. You should see around 190 rwhp.
