Top Speed.

Discussion in 'General' started by midgey46, Jun 29, 2012.

  1. 165 into a head wind , bu99er was hoping for 170 . Private test facility - give or take
     
  2. Isn't the speedo on 2011 models digital as its read from a sensor rather than a rotary cable? If so why would anything other than riders weight, seat position, streamlining, incline/decline, riding toward/away from the wind, gearing be of any consequence to the final speedo reading on the clocks?????
     
  3. because the sensor takes its feed from the sprocket? I don't know about the '11 models but unless it takes its feed from the wheel itself, then it'll always need to take into account sprockets etc.

    Riders seat position etc is not affecting how accurate the reading is, just if it can get up to the big numbers!
     
  4. Aha, good spot on the floor in my thinking Pmsl

    I'm doing Mugello at the end of this month, so I'll try and look out for mine then! :D
     
  6. i would imagine that the brand of tyre would affect the top speed massively as well
     
  7. How do I find top speed registered on bike? 2010 model
     
  8. As far as I know it was removed when the new clocks were used.

    Do you have to have the lap timer running on the new clocks?
     
  10. Ive got a lap timer on there but I've never used it. Will it register anyway?

    Do you really need to do that? Just do what I did... run it up to the rev limiter in 6th and look down at the speedo!

    was haring down my usual top speed stretch this morning and the speedo was indicating 160 which i always thought was pretty much the limit but then about 2 seconds later it suddenly jumped to 163

    any ideas why this might have been?
     
  13. Maybe there was a bump in the private runway you were riding down, and the wheel spun up a little.

    :roll: Obvious.!

    An accumulation of dirt momentarily effected the chromasity of the paintwork, making your red bike slightly more grey.! ;)

    Both of you are wrong, the bike was evidently so shocked at going at that speed that it turned white for a moment, hence the faster speed. :D

    Phrased badly... it was shocked at going 160... turned white... then went 163! :D
     
  20. 168 out of Gina today and she still had more to give I'd say she would go to 175 indicated...
