2020 V4s suspension discussion

Help Support Ducati Forum:

So finished up the suspension work and ended up here:

Front
10/15 preload.
Free sag: 28mm
Rider sag: 40

Rear
17mm preload. (6mm less than stock 85n spring)
Free: 14mm
Rider: 32

I am still bottoming out the front forks with the 11.0 springs. I can’t believe I’m going to have to go to a 12 at 220-ish pounds fully loaded with gear. I’m at 10 of 15 preload adjustment. Was 13/15 on 10.0 springs. I would’ve thought a bigger change.

It’s only happening on 160mph to 40ish HARD BRAKING… and on the track where I’m coming down from even faster. I think it’s going to be worse….
Reduce your air gap. A little bit makes a lot of difference (there’s a chart in some of the Ohlins fork manuals that show how quickly the force increases as the gap reduces). Maybe 10 to 15 ml of oil per side at first and see what happens.
 
How did you setup the Slacker when you measured the front? Were you bottoming out your xx99 bikes?
Used mag on the slacker to stick to bottom of fork. Tried to ensure it was in middle of tube.

Yes on the ‘99 bikes. Was much worse as the bike was base model.
 
where is your rear ride height at?
Did you put the forks back in at the same height?
Within 2mm of stock bike. Did not adjust the eye bolt. Both springs are identical 160mm. And I’m less 6mm preload.

Forks exactly the same position

Will try this next. To confirm. Air gap is set without spring installed and little plastic spring holder. ?
