Every time I see something like this, I always assume that it's on the German autobahn with no speed limit. Looks like the Z650 is getting a lot of vibration.
Where about were you riding? Typical city road? And how do you like how it rides in whatever situation you had it in?This weekend I took my Z650 out for a ride. Very quick of the line and keeps accelerating. Of course it's no 1000cc racing machine, but it has plenty of power. Due to bad/cold weather and new tires, I closed the throttle at 160km/h (100mph). I must say, at that point, the bike was still accelerating pretty good. Although it's basically the same engine as on my Vulcan S, this one is a lot quicker.
Just how long of a road does it take for you to reach 125mph? Seeing the video, would you say 2-3 miles is a good distance to try to hit top speed? I assume any distance under that and you'll be struggling to get pass 190km/h or 118mph. It seems like the powerband tapers off pass 9.5K.125mph. Between Tucson and Phoenix. Long straight and level. Had 125 on the speedo for at least 30 seconds. Down to 100 then back up to 124. Couldn't break 123 the next day on the same stretch of freeway. I'll try to set up a camera next time.
