welcome to the forum duck (im NinetySix from cbr250.com)
the 2000 onwards 9R's run 12.2:1 compression compared to the 98-99 models ~11.8:1... which requires a minimum of 95 RON fuel, compared to the 98-99's minimum of 91 RON (tho ive tuned mine for 95 RON). im going to hop on the anti anti-optimax bandwagon too, theres nothing wrong with it... tho it helps to have the bike specifically tuned for what ever fuel you run.
ill say it again, you will have trouble getting a better deal than this bike for 7k

not sure what kind of rubber it has on it but looks like it might need something better
theres plenty of reviews on the net for these bikes, including many unbiased reviews... most of them put the 9R behind the R1, 929/954 and GSXR 750/1000 in terms of track riding and they are right to really, the 9R isnt quite setup to turn as quickly (or as nervously) as the competition... tho raising the rear and dropping the front end can change that quite dramatically, tho you will probably need a steering damper after that (stock there is absolutely no need for one)... MadKaw on this site managed to run a 1:42 on his 99 9R track bike at EC (it also ran 1:44 at PI) so they have the potential in them
how ever the one thing all the reviews agree on is that the 9R comes up as the #1 real world street bike... hop on one and you'll know why

the ergo's are fantastic and its a nice stable bike with plenty of wind protection.. they are perhaps the most under-rated bike in existance
also plenty of modification potential with them too, a good 10HP to be had with a full system with almost zero loss of low down power, timing advancer works wonders, stock air filter only needs the mesh taken out of it to work great and all the mods you need (including jetkit) are dirt cheap from the states. or they go great stock. kawasaki got the ram air system bang on pretty well, they have a fair top speed advantage over the competition (bar the gix1k) and you can really feel an extra surge in accelleration in the higher gears

build quality is quite good too, and these bikes are seriously easy to work on if your that way inclined.
there is bugger all that would be wrong with it with only 11k on the clock... its typically only the 98-99 models that have gearbox trouble as they based most of the bike on the ZX6R and didnt quite make some components strong enough... how ever that was rectified with the E model (2000+)
have you taken the bike for a test ride yet? im sure that would help a lot
