@rac1ngsnak3 that is pretty light - have you asked the place you are buying from what spring rates they plan to send? I DO NOT recommend the Progressive setting on the linkage. Also, have you changed gearing? Like the 1199/1299 these bikes are sensitive to swingarm angle.
 
Any opinion regarding whether to change front fork fluid at 36 months or just wait for a seal leak? Also, I assume that my suspension settings will need to be adjusted if I change my front fork fluid. Is that right?

We ultimately went w 9.5 front and 7.5 rear. Will give it a shot and can always go lighter on the front if we can’t hit the right sag figures.

Will try to source a 1299 rear link assembly.

Gearing is stock front, 44t rear (+1 from stock).
 
@rac1ngsnak3 did you lengthen the chain when you increased the size of the rear sprocket? If not, where is the axle in relation to the eccentric - is it in the 2:00 or 4:00 position? Does the bike fight you on entry or exit? What were your bike and rider sag numbers front and rear? What tires are you using?

1. Chain was lengthened for the upsize.
2. This is a 959 so no eccentric. I’d say we’re about middle of the adjuster.
3. With stock suspension it had no front end feel. Seemed very unsteady while leaned over like every bump or ripple unsettled the bike. Turn in was ok. Drive was ok. No confidence mid-corner.
4a. Stock suspension
  • Free sag front 30 mm, rear 15 mm
  • Sag front 40 mm, rear 35 mm
  • Front preload 11.5 turns out, C8, R6.25
  • Rear preload 6 mm of thread showing, C3, R12 clicks
4b. Ohlins suspension (9.5 Nm front, 7.5 nM rear springs). Aiming for same sag figures. Default comp and rebound settings
5. Currently running Rossi Corsa 2 until pace improves. I don’t think I’m at the limit of the tires. Might try some Racetec TDs with experience. Seemed to wear ok. On OZ GASS-RS wheels.

My riding position could be improved. I felt like I couldn’t get off the seat enough. I installed new rearsets so foot position will be 20 mm higher than stock. Might increase a further 10 mm higher with a few more trackdays under my belt.

The rebound damping looks too fast to me based on the front of the sipes being rounded while the back is sharp/square. I'll let others chime in who may have more experience.

I was thinking the same. It was more pronounced before slowing. I think rebound may be maxed out or close to it.

Maybe the preload is too soft and causing the rebound to work harder. Were the rear sag numbers good (or stiff enough)?
 
It was “set up“ by Dave Moss about 3 yrs ago when I first got the bike and then played around w his baseline.
 
9.5 Nm front is too stiff for my weight. Unable to make the recommended 40 mm sag. Got to 37 mm with all the preload backed out (18 mm). I’m thinking going down to 8.5 will get me there with some head room.
 
Hi. Just picked up a Pani 959 totally stock suspension (Sachs and Showa BPF). I have a track day next Tuesday at Silverstone (very fast and flowing). Inters group. I weigh 170 pounds in all my gear. Pirelli SCs, which I will run 32/26 cold.
I dont have time to get the bike set up professionally by Tuesday but my Daytona was set up and I like it.

Pani 959 Numbers

Forks rider sag 43, static 16
Shock 32, static 5
Comp and rebound I have set per manual front and rear, so standard

I have ridden the bike about 250 miles on the road to get used to it and am using all the travel in the forks.

My Daytona sag figures are Front rider 35, rear rider 32.

Currently Im thinking of adding front preload to get the front rider figure to 35 and add a turn on compression on front.

Any comments / sugestions?
 
@RBen your numbers don't make sense, are you sure you measured the bike and rider sag properly? Stock springs? Is this a used bike or new 959 with suspension from the factory?
 
used 959 on stock non ohlins suspension. Im using a Motool slacker sag device.
 
First ride on Ohlins this morning and wow! What a difference! Even with too high of a front spring the bike felt noticeably better. I'm not sure what Dave Moss is smoking but I don't think he was measuring sag correctly or when he pulled all that preload out it considerably changed the geometry. I didn't see or hear his numbers that he was measuring but I think there was way too much sag/decreased ride height. Because I'm now standing more on the balls of my feet vs flat foot w DMT "tuned" suspension.

One question, when doing sag numbers how much fuel do you have in tank? I did my sag numbers w a pretty empty tank.
 
My numbers look good in the front for my 2021 V2 (26.25 avg free sag, 40 avg rider sag); however, it requires 64 (all) clicks of preload and I have 3 mm (sometimes zero) left after hard braking (using 100% comp damping). Clearly, I need stiffer springs. I am 184 with street riding gear. I am not sure of the spring rate for the stock springs, but maybe Racetech or someone here can guide me on what I need.

FYI - the rear preload and rebound are set up correctly and are not launching me over the bars, causing excessive push on the front end.

Stock Showa forks have 5-6 mm of dead space when bottomed out. We checked when servicing my forks w no spring
