I did this one way back when the first forum started and it was a lot of fun. For me, it was my 1983 Yamaha XJ900RK, or Seca 900. Had her for ten years, and two weeks after I sold her in 1999 a friend brought me a copy of Motorcyclist that listed it as number three of their top ten of all time to hold on to. I would buy another one in a second if I had the chance.
