I have a 2007 Bandit 1250 with 51,000 trouble free miles on the clock. It is a very good motorcycle with lots of low end torque and about 100 hp. I have ridden it on long distance and short rides and was always satisfied with it once I had Spencer do the seat, new Bike Master Daytona Bars with 2" risers and 1 1/2" pull back.
I also have a2011 Concours with 44,000 trouble free miles. This bike is heavier by about 145 lbs. but it has the solid waterproof saddle bags, heated grips, electronic wind screen, ABS and Traction Control. This bike is a real great long distance and mountain rider. I've never experienced any heat issues even in the Summer here in Sunny California. I did replace the stock seat with a Russell Day Long, which raised the seat height up 1 1/2" but was well worth it. Easily a 500 mile per day rider. Shaft drive with a 5.8 gallon fuel tank. Averages about 45 mpg, depending on speed and riding conditions.
Unless you can do your own Valve checks, at every 15,000 miles, it will cost you about $700-1000 at a dealer for this and a plug change, radiator flush and oil and filter. A very labor intense undertaking.
I love both bikes as they are very dependable and are fun to ride.
I'm attaching a picture of the Concours but couldn't locate on of the Bandit.
I hope this helps with your decision.
