I am doing a project for class about the Harley Davidson Fatboy, and I need to find the values for the spring constant of the bike used in Terminator 2, and whether or not it used a custom suspension. I found the normal suspension used in the 1990 Fatboy are telescopic forks with a 5.1 inch wheel travel in the front and twin shocks with a 4.1 inch wheel travel in the rear, but I cannot find their actual values.

  • Sounds more like a question for Movies.SE – Pᴀᴜʟsᴛᴇʀ2 Nov 17 '15 at 0:49
  • That or Physics.SE since he wants the spring constant. – Poisson Fish Nov 17 '15 at 15:13
  • Harley does not publish it's spring constants. As well, many manufacturers us progressive rate springs that are not a constant. If you were to use a motorcycle with an Ohlin's suspension you can get all of this information from them. An example would be a Ducati Panigal S or an Aprilia RSV4 Factory. Good luck, hope you get an A. – DucatiKiller Nov 18 '15 at 1:02

    I'm voting to close this question as off-topic because this is regarding a special motorcycle for a movie and there is now way for anyone can know the answer to the question. – DucatiKiller Mar 3 '16 at 6:36
