I've had my 850xs for many years and love it. The motor is amazing if it's tuned correctly and has tons of bottom end torque and yet great top end power as well. Do I like it as much as my xs650----no but they are two different bikes. 850 is more of a touring style and also very comfy with a passenger. If it's real clean---$1500 is fair -- if not--$1200 is norm with that mileage. A good website for this bike is (yamaha-triples.com) and should answer any questions you may have
