It's the exact same as the 05. When it's new it will get up to 67-69. After about a month it will drop down to the 63-66 range. The drop in top speed could be from the intake valves tightening up, just keep that in mind when you see a loss of top speed.
One time I hit 69 but I had a pretty good wind at my back. For the most part, 67 was the top speed until I hit the 200 mile speed drop off. I put on bigger tires at the same time I had the valves adjusted so I don't know if the top speed would have come back up.
