What about it makes you believe it's an 883? You can't go by looks alone.
My first thoughts too. You can have a machine shop overbore the jugs and install a 1200 kit yourself fairly easily. Can't go by looks alone.
Do a compression test on it and see if it coincides with the numbers of an 883. Often there are slight variances that can hint in one direction or the other. The true way to check is to pull the jugs and measure the bore, but that can get costly and time consuming, and most places if not all would have biiiig problems with a test rider doing this.
Still, take it to another dealer and express your concerns. If it has a 1200 kit, it likely will have a tune as well. If it has a tune that is set up for a 1200, that is a good sign. If it doesn't have a tune, I would run hesitate on the deal. Just my $.02.
Is the stroke any different between the two? An easy way to check that is putting a pencil down a plug hole and rotating the engine. This is the only way to tell the difference between a 360 and 390 on old ford trucks (measuring stroke).
If it's a 1200 kit the heads, pistons and jugs are different and the dealer should have documentation if it was done by a dealer...Like other have said, don't show your *** just ask them to show you how you tell the difference. It shoul significantly more *** than a stock 883.
Do not judge a book by its cover (do not trust what the bike looks like). I know for a fact that it should at least sound different than an 883, get more power. Send it to me and I will tell you!

You can't bore the newer sporty jugs. MoCo went with thinner side walled jugs somewhere after '07 or '08.
Oh, and some people/places will re-use the stock 883 heads. The heads are stamped on the bottom side. My tank and heads still say 883, but it isn't an 883 anymore.

Just becasue it has the stock AC on it does not mean it does not have a 1200 kit in it. Sure you would think thye would upgrade the AC, but not always the case. Just know what your talking about before you go to the dealer making an issue.

Stroke is the same. The only difference is in the bore. 3.0" for the 883cc and 3.5" for the 1200cc.
1. Add 300 ml ethylene glycol to 300 ml Dot 5 brake fluid
2. Remove the rear cyl spark plug
3. Insert a wooden or plastic probe
4. With the motor in top gear use the rear wheel to rotate
the motor until the probe shows bottom dead center
5. Elevate the rear wheel by 0.76 meters
6. Carefully pour the fluid mixture into the spark plug hole
7. If you use it all up your bike is a 1200. If there is
158.5 ml left over then it's an 883.
The only change made in most 883 to 1200 upgrades is the bore diameter, 3.0" vs 3.5".
For the average person to check it, you'd need to pull the heads and measure the bore.
