"Of course, it's very important (to win back the title)," the 26-year-old Bolt said of the 100m crown he lost to injured teammate Yohan Blake when he false-started in Daegu, South Korea, in 2011.
The loss however has hardly scared an impressive resume that includes Olympic gold in the 100m, 200m and 4x100m relay events in Beijing and London, and five world titles.
"I want to keep winning every race that I compete in, and the 100m and 200m finals in Moscow will be the biggest races for me this year," the Jamaican said.
The world record holder in both the 100m and 200m added: "My season has been good, I'm getting stronger every week and my execution and speed endurance is steadily improving. Right now I'm in good shape, focused and feeling well, training hard, and I'm ready."
