I put this together a year ago and have now made revisions. I will edit this post as needed. Data was taken from all the Service Manuals available to me.
Hope you find it useful..... admins, request this be made a sticky.
Notes added 12-2, Some additional thoughts - I had added info for SOFT and HARD settings of rear shock, essentially with a calculation to show actual spring rate when the two springs are in effect when set to SOFT. However, the Gen 1/2 numbers for look very low and unreasonable, despite the proper formula for springs in series. One does not know factory preload in that setting, and one would tend to think there would be at least some, or enough to boost the effective load carrying capacity. The HARD setting numbers are simply the one spring K1 in effect as the K2 is locked out.
Just for reference, I have now installed my RaceTech shock on my Gen3 with an 850 lb. spring, with a touch of preload, but it is right on the money for a 190-220 lb. rider, validating that the RaceTech rear shock spring recommendations are high/too stiff, thus use Penske's recommendations.
Keep yer stick on the ice....
