1996-2003 Springs For 1200 Sport Model

  • Length is 13.5“ “eye to eye”.
  • The factory dampers for piggyback shocks for S models are now obsolete from the MoCo and not rebuild-able 12). So when they go bad, they have to be replaced either with a used or aftermarket set.
  • Some spring weights:
    • The 1200S shocks have a 54/78 lb/in spring. 13)
    • The 12.5” 412 has a standard 75/120 lb/in spring for 180 lb riders. 14)
    • The 12“ 412 has a 90/130 spring. 15)
  • Be careful, if you need to replace the bushings, not to crack the dampening wheel at the bottom of the shock. 16)

2006-2007 1200L

  • 2007 Harley 1200 Low Springs 100 pounds per inch progressive wound (but built by Harley to go progressive too late to help much. It goes to hard rate at a spring height of 6“ or a shock length of about 10.5”) 46)
  • 2006 Harley 1200 R shocks a little too much low extension damping but appears to be acceptable 47)
    • Preload adjuster set to full hard to give about 20lb. of spring preload at 13.25 c to c on the shock (the only setting that is acceptable due to spring length). 48)
    • Ride height ends up 1.33“ from full compression, (with a 200 lb. rider) and 1.9” from full extension (bike on a jack) 12.5“ shock c to c with the bike on the Low stand. 49)
  • Shock length fully extended: 13.25” (you are in this range any time you crest a hill at high speed the trick is to keep the tire on the road at all cost) 50)
  • Shock length with bike straight up no rider weight: 12.1“ (you are in this range every time the road goes down, it happens just as often as the road goes up) 51)
  • Shock length with a 200 lb. rider: 11.4” (you are in this range right after a raised or rising bump) 52)
  • This is all spring rate trying to save hardware.
    • Shock length fully compressed 10“ 53)
    • Shock length with the bike on the kickstand 12.5” (this is a bling thing and it's not significant for handling. 54)
