2019 V4 does it have clutch issues

Ducati Forum

Help Support Ducati Forum:

A smaller diameter hose will increase the pressure at the slave cylinder so in theory it should improve clutch actuation. I've changed out my slave cylinder for one with a larger diameter piston which will hopefully improve the system, lessen the throw of the lever and bring the biting point closer to the grip.

Which slave did you go for? Oberon?
 
clutch issue

...., not cool for a 20k bike, just not acceptable
 
He is replacing with CNC Clutch Slave Cylinder

Correct. Sorry not had much time to post on here as currently overseas on a training course. TBH anything is better than the stock slave cylinder. Ive used Oberon on many bikes and never had an issue. The specs of the CNC version are very similar in that respect so thought I would give it a whirl.

What size slave will I need for the V4? looking on their website there are many to choose from.
 
Darkling I trust they are coming to the party with new fairing if the brake fluid damaged the paintwork, I would expect that & not just a f***en repaint either.

Yes was told by my dealer about the 3mm to 2mm dia refit on the clutch hose, he alluded the issue is with the piston in the M/Cylinder.
It makes you wonder why Ducati changed it from models that they had on previous bikes which had no issues.
My V4 goes in for a sticker kit next week, week after the oil cooler, cam tensioner re-torque, clutch hose (If there) the mech broke his foot and then got DVT so is out for 3 weeks.

I am just thankful I have other bikes to ride it would drive me bonkers not being able to put tar under the wheels every day.
 
Just dropped of mine for the clutch hose , oil cooler and 3 more. My bike is at 5600 miles and I love it dearly, but clutch on mine is absolute .... in terms of sucking air. It used to be an issue just on track, but now it goes flaccid after a few street rides. I can’t see how smaller diameter hose will fix the problem though, but who knows.

If it continues, I am going to invest in some parts.
 
I had both my master and slave cylinders rebuilt around 4800 miles, was having to bleed the air out every 500 miles or so prior to that. After the rebuild, I haven't had any more problems with it. At around 7300 miles now.
 
Ducati philosophy

It is because of the devout Ducatisti. They have encouraged Ducati to create the generational company Philosophy: "Just deliver the bike to the customer." "Let the customer discover all the manufacturing and suppliers part defects, and have them bring the bike back to the dealership to address the problems." Ducati saves money on R&D, and the Ducati owner gets the full Ducati Experience (of having their bike in the service department more than it is on the street/ track, mainly because of the backlog of parts and bikes there for warranty work). Which serves another revenue generating purpose for Ducati. You buy other parts and have other work done thats not covered by the warranty. Also, you get to see the newest bikes (or the ones that didn't sell from the year before) on the showroom floor that you might purchase to add to your "Ducati Experience" (the customer realizes that at least 2 bikes are needed to stay on the road during the bike season, alternating them back and forth to the service department)
 
I have to agree that QC on the parts in question is lacking but more importantly it would make more sense to test a few pre-production models on an endurance basis, that is to say in varying weather conditions and on both road and track to allow the design to show up any flaws or failures before they get into the hands of consumers. Mclaren for example put over 10,000 miles on their P1 before it was even considered ready for full scale production and that was under extreme loads and at all speeds. MIRA is a testing facility in the UK that punishes a car's suspension, brakes and is as good a place as any to draw out any underlying issues that may not be present on a test rig or at least exhibit any shortcomings long before a vehicle hits the showroom floor.

Just had my clutch hose done by the dealer. I can't tell for sure, but even though the lever was proper firm, the bite point seems to have moved to about 80% of the available travel away from the grip. Modulating the clutch is not so easy.. I kept adjusting the clutch lever to be close to the grip since no sense to be moving the lever back and forth when it only bites at almost fully released.

Dunno, but this was my first impression. It became more 'on and off' when before or so it seems. But as long as it doesn't draw air, I'll call it a success :)

If you are having to adjust the lever, it is not a good sign

I believe you still have the problem
 
i think what he is saying is the clutch now engages and disengages at the begining of the lever pull which is good


You are right

I got confused

Hope the problem got fixed,

really looking forward to having a nice 26k bike with a working clutch, as I have had on the past on 5k or 10k bikes

Correct. On this bike even when the clutch is fully operational it is still not the greatest thing to use at slow speeds and in traffic. all my previous bikes had clutches that you simply didn't think about, but this one is different. Clutch feel on my Tuono is superb too, silky smooth, progressive and very pleasant to use.

Ducati QS is good and that's why the way this clutch operates is only a minor gripe for me (apart from it drawing air of course), but I wish it was like the one on Aprilia..
 
i only use the clutch for take off and tight u turns, i agree its not the greatest clutch but i dont think its the worst either lol
 
I replaced my 1299s with a V4s last October. The V4 clutch is certainly a big improvement over the old clutch. I have not had to bleed it since new. Incidentally, I also purchased a Srambler 1100 Sport last May, and its clutch is excellent - nice and easy on the hand.
