Hello:

I've been reading about the problems endemic Magura clutch systems and in many forums recommend riding these two options:
http://www.oberon-performance.com/ac...ders_KCSC.html
&
http://sigutech.com/index.php?option...ask=view&id=28

I disassembled the RECEPTEUR EMBRAYAGE KPL. 27MM OEM: 59032061044. I've cleaned perfectly and I've changed the O-ring. By introducing the piston and slide with the push of the fingers, I sense that the movement is not linear. I sense that there are many phases of slip resistance and the tour takes place in steps.
Immediately I thought this piston sliding leaps could be causing the sudden push happens when releasing clutch in first gear. Everyone talks problem clutch discs, but I think this irregular operation EMBRAYAGE RECEPTEUR may be causing the problem of clutch in first gear.
I think it's absurd to release the clutch lever gently, if after the RECEPTEUR EMBRAYAGE it translates the movement of the hand jerking.
Can anyone make any recommendations on this?. Any recommendations on Oberon or Sigutech system?.


Also I have problems in the clutch level. Oil oozing gum constantly. I disassembled the PISTON 11MM and can not replace the seals. There is no other option, you have to buy a new set OEM: 75002032000 for 40 .
I read in some forums that the MASTER CYLINDER CPL. Magura 11mm is not good quality. Some talk of installing one of the Brembo brand but do not know much more about it or if it's an exaggeration. My bike has 10,300 miles and oil oozes constantly. Can anyone make any recommendations on this?.

Thousand apologies for my English disastrous. Greetings to all.
I wish I could help you with your problem, but unfortunately I have no idea... Please don't worry as I'm sure that you will receive prompt help from other owners of this INCREDIBLE bike, or at least they can help you with some information

This is the good thing of these type of forums: We all can help each other, so that we can do things by ourselves, saving money and learning to repair the bikes while we are exploring the world

I took these pics in 2009, and I think it was a 2008 Dakar bike. The rest of the pics are here (pages 520 and 521):

I hope that I understand your problem properly but is the ooze coming from the clutch slave cylinder???
If so it may be the shaft seal ring (PN 0760 172871) in the clutch cover Part #6 - here;
http://www.boltonmotorcycles.com/find/fiche/217455
These are a problem with the 950 - causing a leak at the slave...

Can you post a pic of the problem if this isnt it..

I need the bike for next week. I could not wait any longer.
I purchased this item:
http://www.oberon-performance.com/ac...ders_KCSC.html

And I bought the set:
REP.SET PISTON 11MM 07 Ref: 75002032000
http://www.boutique-ktm.com/pieces/m...077620210.html

I hope that these pieces will settle the matter.
I will comment on the results.

That's a genuine Marc Coma 2005 KTM 660 Rally Factory bike if anything. Not really comparable to the 690 RFR in this thread since it's a different construction with a different engine. Chain drive opposite side etc.

Nice bike! You don't see many of those

On many occasions this problem is due to worn piston rings. How old is the top end?

My bike has 10,000 km. The aluminum residues sludge was evident.
I find that it is not a theory. Today I mounted the transmitter Oberon clutch and my theory has been confirmed. I said goodbye to the start jerking in 1st gear. Now I can release the clutch lever as I please because I have never surprises, no more sudden shocks and jostling unpleasant. All theories of change clutch plates and seals are a mistake. The problem with this bike is the damn Magura clutch system that is a real shit.
The next change will be a new Brembo radial pump clutch. that allows for gear changes less force applied to the lever.

Someone with mechanical skills could ensure that this pump would work perfectly in a 690RFR?.

http://www.ktmtwins.com/ktm-rc8-950-...ial-clutch-kit

KTM to replace the OEM sells 950 and 990 Supermoto SuperEnduro. These pumps are of 10.5 mm diameter piston.
The RFR 690 has a pump piston with a diameter from 11 mm. In theory it should be valid for use in RFR 690.
If possible, I was interested to buy this:
http://www.motovationusa.com/mvstore...idproduct=1022

... but it's a lot of money to spend if not safely.
Thanks for the replies.

I think I misunderstood you, is there oil coming out of the master cylinder at the bars? I was addressing this problem in my reply which can be a result of worn rings blowing into the sump pressurizing the cases and pushing back clutch oil out of the clutch lever, very common as the case seal on the clutch side is very small and teflon!

The jerkiness and grabby clutch on a 690RR ( Rally Replica) is something I tried to fix also, I asked the factory mechanics on many rallies about this, the only thing that fixed it on my 690 RR was 2 things, remove all the plates, you will notice an edge on the plates where they have been stamped out, all the rough edges need to point towards the outside of the bike, drop the oil and install the Motorex 20W60 oil designed for high performance singles, it solved my problem. All this came from a 65 year old original rally mechanic for KTM who did much design work on the 690RR - Walther was his name if I recall right, he also showed me the trick of pushing the front brake caliper with your knee across the disc and then pulling it back, this removed the softness of the lever ( after every stage ) and made it firm again, he said the Titanium caliper bowls flip the rubber seal when they get hot and increase chamber sizes, by pumping the caliper it flips the seal back......i must have bled the front 5 times trying to fix this issue!

Has anyone got any spare grab handles they want to sell?
On my friends bike he's had the bolts pull through on one of the handles.
If we can't find the original plastic ones I'll probably make some aluminium ones.

The oil oozed out exactly by the inlet orifice of set Piston 11 mm.

The sliding piston in the old OEM clutch issuer was clearly irregular. There was not a linear slide. That meant that when you let go of the clutch lever slowly; the bike started with pushing.
In my case, for now, the problem is solved.

Now I need to solve the problem of hardness in the clutch lever. So I ask about the option of Brembo.

Those handles are mucho $$$ think over $300 each as listed.

Spare tanks I have - handles I do not.....
