Aftermarket Clutch Slave Cylinders? - Ducati.ms

DrJ · Apr 6th, 2011, 6:30 pm

The other day I put some Pazzo levers on my '10 Evo Sp. Because Pazzo does not make long levers for my bike, I purchased the short ones. Now, I'm having some difficulty pulling in the clutch lever due to the lack of leverage. Therefore, would an aftermarket clutch slave cylinder resolve this issue? Are some better than others? Which ones would you recommend?

Thanks for your input.

Short levers make it pretty hard sometimes
Some tricks would be to remove two springs from the clutch pressure
This works rather well and makes the pull a lot lighter and the clutch will not slip.
I have seen many people with dry clutches do this trick without any problems. I ran this way for a while and it works!

other wise
We do offer a nice alternative for Slaves That can help somewhat with the pull
A 28mm clutch slave from Aella
Tapered style

or Bevel style

Both these have state of the art construction and new design
The pistons have a special anodized coating which allows smoother operation. another benefit is these slaves do not turn the clutch fluid black

I almost bought a clutch slave cylinder today at my dealer, but wound up buying CRG levers first.. the parts manager and one of the mechanics explained that the clutch slave cylinder will give a lighter pull to the clutch but may not make shifting any smoother or finding neutral any easier with the oem clutch parts.. i chose to rather upgrade my levers and wait till I've got some more miles on the bike to see if i still want a clutch slave..

however, in your case, a clutch slave may be your answer, especially if you still have oem clutch springs, oem pressure plate and essentially an all oem clutch, mixing and matching oem parts with aftermarket is sometimes tricky..

for a clutch slave, I considered the STM 30mm and Evoluzione 28mm... I felt the pull of a Evoluzione 28mm on a 1098 in the shop, and it was a soft enough pull for me..

EVR 30MM can be found on ebay

Reduced pull in effort by about 20% with H/ D clutch springs
This is a huge differance in traffic stop & start on your left hand

checked forums here on EVR

The bigger diameter you use on your slave cylinder, the softer the pull should be.
I think the biggest out there is made by NCR, 32mm

oberon makes a nice slave in a 30mm and it cheap..and works alot better than my stm i had..i have short levers as well but due to a 5spring duca bike slipper i can pull with one finger..also used black coated barnett springs/soft.

well done. You are a good person for giving solid advice first even though it doesn't do anything for your business.

I was going to offer the same advice, but you beat me to it.

Aftermarket slaves usually come in 28mm, 30mm, & 32mm, with the 30mm being the most popular, I run the 30mm & long levers with HD (6) springs and my pull is butter soft.

The bigger diameter you go the easier the pull will be, but the "push" will be shorter, & the clutch pack will not "separate" as far, so when you run the 30mm & 32mm you will have to pay more attention to the clutch pack height, or you could run into problems. Aloha Alex

Thanks Freezer
The least expensive is always the most satisfying.... so you can shed your money on other farkles
I still on occasion will remove two springs if I know I will be doing lots of stop and go. Super easy to do especially on a open clutch

amazing how well this little trick works ehe?

Tru dat
If your hitting the track the larger Diameter is great since you don't need to find neutral.
but for general service the ø28 is perfect
