Welcome mcampy,
First, the removal of the wheels from the bike is as easy as any motorcycle gets. The bike comes with a center stand. The factory supplied tool kit is sufficient. It's even easier with real tools (ratchet, sockets, torque wrench to set correct torque values). Or are you talking about removing the and remounting tires from the wheels? That is more work, but typical of any other tubeless tire job.
Check the wiring harnesses pictured below. These zip-ties were too tight coming out of the factory (red arrows) and can damage the wires and cause electrical difficulties. The picture below has no headlight... the zip-ties are behind the headlight, and hold the harnesses to the horn bracket.
I would test play at the rear wheel (with bike on centerstand) to see if there is any play. A rear wheel with play is going to need a new bearing in the final drive unit, or a pivot bearing.
Lastly, I hate to be a downer, but since you asked....
Watch the warning lights when starting up and taking off, especially the brake warning lights. The brake warning lights will go through a routine, when you get moving and you get to about 3-5mph, the last flashing light should go out and all of them should be off and stay off. The bikes before 2004 (like the one you are looking at) had less reliable ABS systems (expensive to replace the ABS unit). I would make sure that the owner has proof that the brakes were serviced regularly. The basic 12,000 mile service does not include brake service (the brake service intervals are based on time, not mileage). So the owner would need to request a brake service in addition to the standard 12,000 service. I would not buy it (I wouldn't fly out to even look at it) unless the owner has proof that he has gotten the brakes serviced regularly (at least every 2 years).
I'd be afraid that an owner that rides the bike so little, is not likely to have done the brake service as recommended. Given the unreliable nature of of the older iABS, I would
not buy it unless there is proof the brake services have been done regularly.
this is just my 2 cents...
I was dreaming when I wrote this, forgive me if it goes astray...
