Is anyone able to confirm the presence of a slipper clutch?
All the marketing material etc states that it doesn't exist., however I have seen that the owners manual refers to one.

Page 38 EBC "The Engine Braking Control system (EBC) works together with the slipper clutch to avoid and control rear wheel lockup during aggressive downshifting."

Anyone who has ridden the bike know if it exists?

Lol, you quoting me off the other forum?

From what I understand it does not have a slipper, just the electronic engine braking system.

I am holding judgement on the system until I try it. I am a huge fan of slippers, but I am not even sure you can add one since the ECU may not know how to process it in conjunction with EBC.

Yes it does, on the up shift and very good it is as well. (Never used one before )
I was recommended by the dealership to only use it from 2 gear upwards.
As a few people on the 1199 have had a few niggles, when using it from 1st to second.

I think you're confusing the quickshifter with the slipper.

I'll say this, I went out today and did some pretty aggressive 4th to 2nd downshifts going into corners. Some heavy braking and high RPMs. I couldn't get the rear to chatter or step out, but I can't tell if the EBC is just that good or if the clutch is doing it. If this bike doesn't have a slipper, then it doesn't need one. If I had rode my Honda like that, my rear would have been skipping and hopping all over the place.

That's good news. I'm curious to see how the system performs on the track.

That is good to hear!!

It is a slipper 'functioning' clutch, paired with EBC.
Same as on the 1199 and stock that baby slides into corners nice and predictably with EBC set at 1.

Have you ridden the bike and or own it? Just curious if this is a first hand telling.

Thanks

I am fortunate enough to work with a lot of New Ducati's. So I have had the opportunity to ride most all the 'newer' bikes. The 899 has only been around for about a month now, so I do not have any track experience with it although for street riding it's still a pleasure! I do however have a couple laps logged aboard the 1199 R and and a few more on the S.

Interesting. See now I'm confused, I've heard it doesn't have a mechanical slipper and just uses ebc, but I've also heard it has both. The site doesn't show the slipper, just ebc.

From Ducati USA's website: " The design of the clutch, very similar to the Multistrada and Diavel models, provides for a progressive system which allows the load to be increased on plates without penalising the effort required required by the rider to pull the lever and disengage the clutch. This optimally satisfies both the need of high torque transmission and an optimum comfort for the rider. In sport riding conditions with abrupt shifting down and heavy exhaust braking, the same mechanism reduces the pressure on clutch plates, allowing them to slip as in a racing system, contrasting with the loss of stability of the rear end during aggressive shifting down and offering the supplementary advantage of an excellent modulability during hard braking into corners."

Hence why it is now a wet bath 4 spring clutch. The 6 heavy springs used on the older stock dry clutches are no longer more efficient.

I may be reading in the wrong part of Ducatiusa, but isn't that for the 1199? The 899 reads, "Wet multiplate clutch with hydraulic control" where as the 1199 reads, "Slipper and self-servo wet multiplate clutch with hydraulic control"

That was from the 1199 Technical info. Although I was told it had the Self servo function as well, but they are different part numbers... Hmm maybe it does not.

I recently took the bike out, did very aggressive back road twisties, played with all my gears. The quick shifter is a fine tune melody and down shifting was great. I've tried to find out about the bike having a slipper clutch but I get very confused by reading all the information and technical terminology. last September I went to COTA and all the instructors were on 899s they LOVED the bike and I remember them diving into turns with no problems as far as massive down shifting.
I could tell names of these riders as they know what they were doing and sure they love it.

.....so why is people changing to slipper clutches, is it probably just wanting to add a clear cover and make it look more aggressive?

To each it's own by I love the way it comes from factory. I'm waiting on the right fender eliminator kit because the ones up there just don't meet my expectations as far as clean and functionality goes.

Well, speaking just for myself as having installed the slipper clutch and the clear cover, it is a vast improvement over only having the EBC. I did not install the Yoyodyne for the looks alone... instead, it provides a lot more peace of mind on the street and likely will on the track as well.

If I had more riding experience, it might not be as valuable, but then there are many others that are much more skilled riders that swear by having one on their bike. After all, the 1199, as do most other sport bikes, comes stock with one, so why shouldn't I consider installing one on mine, right?

Good to know that, please don't get me wrong I never intended to say it was bad, wrong or not a good idea. I'm considering installing one myself because it certainly will help. I'm relatively new to Ducati bikes.
I've heard from some club racers they like having not slipper clutch, not exactly sure but I've heard that.
