Rear spring rate

[mechannibalism]

Hi guys I 'm putting a Panigale shock on my GK71F and need to know the spring rate for it (GK71F) or the later models. I weight 130 Lbs. It will fit with out too much trouble I just have to screw in a clevis to replace the ball joint and add a spacer under the piston.....I'll post pics when I got it all done.

No idea, but the Panigale with have loads more spring rate to keep the bike flat with all that power. Measure the sag you have now with the Suzuki shock, then fit the Panigale one with minimum preload and measure the sag. You'll be able to get a spring to suit aftermarket if there's hardly any sag.

Thanks for the suggestions Moforockband but the bike is being ripped apart now. I will check sag when I'm done. I took both springs off the shocks and made a home made measuring "device"- a arbor press, medical weight scale, and a 3" dial indicator. and this is what I got-- Duc spring 220 Lb./in. --Suz. spring 162 Lb./in. so Ill just go from there and see what Demon Tweeks has to offer.

oh, that kind of rear spring, I thought you were talking about leaf springs in the shout box.
