I bought my 89 NX 650 last winter and have put 5000 miles on it. I took it on a 9 day trip and thought the seat was fine but I am a bicyclist and have a tough tush. For the price I paid this has been a great bike and has been rock solid reliable. I have got 59 MPG on long trips and got 50+ mpg with it fully loaded (200 lbs. me in my riding gear and 100 pounds of bags etc.) They all use oil even new but I only went though a 3/4 quart in 1300 miles of hard riding. This is a great all around bike and a bargain if you can find a low milage clean one. I added Answer protaper bars, Cycra handguards, K&N filter, Acerbis fender, upgraded brakes. This bike can do a lot of things pretty darn well. Enjoy..I have.
