How about the engine? It depends on how you ride it but in general, how long does it run for? I heard that boxer engines last very long but same for this engine?
Since I can not test ride the bike and have not ridden one before, I'd like to ask you one more question. How is the acceleration of the bike as compared with R1200GS/RS or Kawasaki ZZR1200 (2004) if you happen to know?
There are usually no major issues with the engine itself (other than cam chain induced, see next paragraph). It should easily last 100,000 miles or more. I have 55,000 on mine and going. Meese has put over 100,000 miles on two or three different K12/1300GTs (each), and probably the same on K1600GTs.
The primary issue with the engines is the cam chain. If it skips a link, then engine damage (valve and/or piston top) can occur. Make sure that the cam chain guard has been installed (a recall) and the cam chain itself is in good condition. A lot of people replace the automatic cam chain tensioner with a manual one. This is an "interference engine", meaning that the valves extend into the same space as the tops of the pistons. As long as the cam chain is good, they will never touch each other. If the cam chain skips, then you can have serious problems, such as a bent valve.
I wish I could answer the question about acceleration. The K1200GT/K1300GT is very very fast and powerful. My K1200GT is rated at 152 HP and 96 lb/ft of torque. That's a lot. I have ridden the R1200GS and R1200RT. Both are torquey at the start but peter out where the K1200GT / K1300GT just keeps pulling hard. I have never ridden a Kawasaki ZZR1200.
The truth is that I am a very gentle rider. Everyone talks about the incredible acceleration and power of the KGTs, but I don't take much advantage of it. I am not afraid to use it and do on rare occasion - pulling away from overly aggressive drivers at stop lights, the occasional freeway onramp, passing on the open highway, etc. On rare occasions, I start up a freeway onramp, look down a couple seconds later, and say to myself "Holy @#$! I'm going 90!", and back it off. I usually don't bother to downshift out of 6th gear when passing large trucks at 75 or 80 mph (Texas I-10 or I-20 only!). The bike just pulls away fast. If you downshift, hold on!
I bought my K1200GT new in 2007. I bought it for its versatility, which is just what I need. I love that flexibility. I can take off the cases for local riding. I often ride in So Cal with only the top case - splitting lanes is easy. I often take it on long trips across the country for business meetings. It will hold everything I need for a two week trip, including business attire, casual attire, a 17 inch laptop, and much more. It has taken me 1,000 miles in a day many times. It took me from Mexico to Canada in 24 hours, and coast to coast (San Diego to Jacksonville Beach) in 45 hours. I have ridden it in all kinds of weather - from 115 F to below freezing. Sunny to heavy rain - with the right gear, it is no hassle. The electrically adjustable windscreen, heated grips and seat, and faring make a big difference.
The things I don't like about my K1200GT are:
* Cost of ownership - parts and maintenance are unreasonably expensive.
* Lack of a way to attach forward foot pegs. On long rides, I periodically stand on the pegs to stretch my legs.
One additional comment: I would not buy any used motorcycle that I could not inspect and test ride myself. No way.
