As a kid that owned a XLC and a XLCH, thats within a mile or two of what those Sportster's would do.Good one, you beat me by six mph. Late 1980's with my 1980 Sporster on the way to work. Just hit the 55 zone and hammered it, about four miles later I stopped for a 4 way stop where I would turn left. Saw the lights comming around the curve about a half mile back. Turned the corner and pulled over got license out by the time he pulled in behind me. County Sheriff walks up and hand him my license, he looks at it and says "Mister Brown you were going 91 mph." Said "I know" and got in his car where the radar still said 91mph.
Said "I know I am getting a ticket but it would be real nice of you if you knocked off some of the milage." "This is not a speeding ticket, after 21 over it is reckless." "It would really be nice if you knocked off some of the milage." We talked a couple more minutes and he wrote me out a warning ticket for speeding and indicated he would throw the book at me if there was a next time. The ticket showed where he got me on radar and that was almost four mile back. Being respectfull and not trying to lie to him went a looooong way that day. Jim.
Or so I was told. A 80- 80 FXS can do better. LOL
