Rear shock spring rate

What do those of you that mainly track your bikes have for rear spring rate? My ohlins shock needs service since I’m maxed out on dampening and it’s still rebounding too fast and wearing my slicks out too soon. While I have it off figured to swap the spring to something more suitable for me. Was thinking to go up to 100 nm/mm since the 85 is pure clean down to the bumper. Will probably have it revalved too while I’m in there.

Bike is a 2020 S and I’m a little under 180lbs without gear and 208 with gear. I ride an advanced group pace.Bike very rarely sees the street so don’t really care about comfort on bumps or anything street related.

175#, 85 rear spring with flipped eccentric on v4r, advance group.

You said you weight under 180lbs without gear and 208 with gear. As well as writing that the bike rarely sees the streets. So you kind of fall closer to the 210lb range which is actually 210lbs-220lbs. For that weight the 105nm/mm spring is recommended. Then again you weight 208lbs with gear and thats under 210lbs. So can also use the 100nm/mm spring. And that spring rate is for riders 190lbs-200lbs. As per Ohlins if you fall in between the recommended weight you can choose one or the other spring rate that you fall between. So you can use the 100nm/mm or 105nm/mm spring. In my opinion since you are 208lbs with gear. And only 2lbs away from the 210lbs 105nm/mm spring. As well stating you ride an advanced group pace. I would say to get the 105nm/mm spring over the 100nm/mm spring. Plus who is to say you wont gain 1-5lbs.

What kind of work or upgrade would recommend or do for a rear Ohlins DU466 thats on a base Ducati 1299 ( shock was purchased with the correct spring rate for my weight)

DU466 with all the correct pieces.

Before you go up a spring, have you played around with the preload? Where is your compression setting at? What shock length are you using? How much fork preload? How much of the fork is above the top triple clamp?

@Mick1976 what is that part in the front of your shock? And what other changes did you make?

Yes I’ve adjusted everything already front and rear. The shock is coming out for service regardless, the oil in it is shot. My ride height is set the way I like it, this was the first thing I did when I bought the bike since it was so uncomfortable.
There is still a bit of preload I can use up but was looking to see if others have found it better to change spring rate and if so what the right rate for this bike with my weight would be. 85 seems like a very light spring.

There’s a difference in the length of the linkage for the 2020+ Panigale. Be careful when using charts or recommendations which may have been made for pre 2020 models.

Richard Boyd's front race shock mount (no longer available), his shock eye, ride height link and rod adjustor. Currently using Ohlins short spring but will be going back to stock length and a new front mount which is due out shortly.

Yeah that was my understanding as well, hence the lower spring rate in the 2020+.
