I bought a 2004 RX-1. Did not add a Turbo. Smooth sled, reliable and trouble free. Problem was I was beat at the end of the day from getting it unstuck. The sled would not climb and was not competitive with the 2 strokes on the flat . I bailed and went to to an 07 Rev. Love the handling and comfort of the sled. A buddy just bought a Nytro with a Turbo. Rode it on the flat and seemed to handle similar to the Rev. Does the Nytro handle similar to the Rev in the mountains. Do you feel the extra weight. Is it time to go back to the 4 stroke?
