14k is a little on the high side. Check the engine for abnormal rattles & noises. Sit down next to the bike and rev it slightly, does it sound smooth or are there abnormal noises? If you can get a ride then test out the clutch, brakes & shocks etc. Look for signs of the bike being dropped, rashes on the fairings, bar ends, clutch/brake levers, engine case covers, exhausts etc. Ask for a service history if possible.
If you know about bikes then a test ride will usually reveal most issues.
