Hello and welcome to the site!
My check list would be:
1. What year 12 is it?
There are some differences in the earlier to later models
2. Does the current owner state any problems with the bike?
Electrical issues are common with the Stator/Regulator and wiring (check the sticky threads on forum). Has there been a regular service schedule performed, and is there any written evidence of this? (owners service book/receipts etc.).
3. Any obvious signs of damage/abuse/poor maintenance?
Usual crash damage signs, poorly maintained brakes/tyres/chain & sprockets, do all lights etc. work?
4. If possible, get the owner allow you to start the bike from cold (no prior start/warm up before potential buyer arrives)
This may help to establish the charging/electrical status of the bike, along with any fuelling issues.
5. Has the bike been used frequently despite the claimed mileage?
It could have been sitting for quite some time unused/unregistered and for what reason? 55,000 miles is not too much for a bike of its age.
6. If possible have someone with you who may have experience with bikes to look it over,
This person may have insight to things you haven't, or wouldn't think of asking or looking for in a bike. Also if possible they may be able to test ride the bike as well. or a least ride/drive behind you as you test ride it to observe things (exhaust smoke, billowing clouds of flame, smoke and engine parts!! (semi-joke).
7. Ride it yourself if confident to do so.
Remembering it will very likely be somewhat more powerful than what you are use to, which feels great at the time, but may cloud judgment.
These are just some of the pointers I can think of, and are general ones when looking at almost any second hand bike. If you have looked on this site, especially the sticky threads at the top of the zx12r page, then they will give you a good idea on what is expected from the 12, depending on the year bike too as earlier models (A1/A2 have some differences compared to B1/5). Others on here can give more advice, I'm sure I've missed some important points but the one's given can be a good start at least.
Good luck with whatever you purchase!
