2020 V4 Base Setup Help

Mr.Alex · May 15, 2022

Hey guys, have a new to me 20 V4, but for some reason I find this bike to be very hard to turn. For a backstory I will say my friends have a 2019 V4S and at one point in their early setups I thought that bike turned in way to easily. I suppose the updates for 2020 remedied that instability. But now for me the bike is just not turning well at all compared to the other bikes I've owned. I've set the sag to be close to 40/35mm. Is it something with me? Or does anyone else feel this way? Just feels like it takes a ton of bar pressure to get it to turn in and hold it there, bike just wants to stand up a lot or I feel like will tuck the front if keep up the bar pressure.

I believe the front forks are at OEM height. since I cannot play with the height of the rear shock with base hardware, should I consider raising the forks?

Also, does anyone know the stock rebound setting on the stock shock? The manual actually has the ohlins shock in there with the ring adjuster on the bottom of the shock, but I have just a screw type adjustment there, which has only 1.5 turns of adjustment.

190lbs with no gear
Front:
Preload 1 turn out
Comp 6 out (stock)
Rebound 4 out (stock)

Can you get the rear to 30mm rider sag?

OEM rear rebound is listed below.

Are you sure you're on the right adjuster? Rebound is here. Clicks are soft, but they are there.

Is the bike hard to manoeuvre at low speed?

Yes that is the adjuster, I def cannot feel the clicks, it just feels like it turns. Its also hard to really turn it there as the rear linkage (?) is blocking half of the accessibility. I will try to feel the clicks this time around.

Wont 30mm in the rear be a bit too harsh for the street?

Are you referring to just like parking lot speeds or just slower speed turns like even turns around town or backroads? Regardless the answer is really both, I have to give quite a bit of bar pressure or fully toss my body into the turn to really get it to go along with bar pressure. I feel like my R1 can do the same with just a finger push on the clip on.

I should also mention that this is mostly a weekend warrior/nighttime warrior street bike, no city cruising unless just have to get to the roads i am heading for.

Before I set the Sag, the front preload was 10turns out and 49mm of sag, rear was 40mm of sag. The bike felt pretty similar to how it does not except now I feel like the turning is bit worse, perhaps because the front is not being compressed as much?[/QUOTE]

There are clicks there, they are just really soft. You may try adjusting it with someone sitting on the bike or gently pulling up to see if you can get at the adjuster more.

I don't think 30mm is too harsh at all for the street. I'm also running a 105Nm spring. Its what my bike is at right now. Higher than that it feels like it wants to squat too much under acceleration. My static/bike sag is about 13-15mm. To get to 30mm if you are under 10mm static/bike sag you may consider a new spring, but I haven't found a off the shelf replacement for the Sachs shock spring. The listing on Ducati Omaha's website is wrong for the V4 Sachs shock.

If you feel like it has understeer, your fork rebound may be too fast and shock rebound too slow.

Your steering damper may be set too tight, not sure if it's adjustable on the base bike?

I remember reading the 20 got softer ones up front. I can try to do the 30mm but somehow setting the sag kind of made it a little more difficult to turn. The rebound is currently at stock settings and when pumping the forks does not seem to be too fast nor too slow as it does not do the pogo stick thing. I can try checking the rear with clicks but I have a feeling it's closer to the stiffer side as well

I can understand the thought behind it since I played with my friends v4s dampers a bit, but even on the stiffer setting their bikes seemed to just turn much more easily. Which is why I can't figure out why I'm feeling this way

So I rotated the rear rebound a bit and then could lightly feel the clicks. Set rebound to stock and maybe tiny diff. Checked the front fork showing and it's same as another base 20' . I also put on the Ducati performance tank extender and that helped me slam my body into the bike to get it to turn, but still hard work. I tried my friends 19 V4S and back to back you'd be hard pressed that it's almost the same bike.
