After much hesitation, I purchased and installed an Oberon slave cylinder for my '98 5th gen. It costed over 200 euros including purchase, shipping, customs fees and installation. I was expecting a decent improvement, but as soon as i picked up the bike from the workshop, the disappointment was almost total.
The load required to operate the clutch has decreased by 10% - 15% in my opinion. Not more. Pretty much a negligible gain. The only advantage is that the lever is smoother, but that probably comes from the fact that the old slave was 25 years and 75,000 km old. The effort to pull the clutch is almost the same.
I am so disappointed that I would be tempted to take it apart and resell it, but it would not be worth it.
The most irritating thing is that the point of engagement has remained almost the same, a sign that the leverage ratio has not changed much.
In my opinion it could have been increased slightly (there is still a lot of travel) but evidently in the design phase the leverage ratio was not increased further to avoid problems.
Surely my rhizarthrosis is quite demanding, but ultimately a bigger slave is useful only in combination with other interventions (clutch springs, clutch lever, master cylinder, physiotherapy, etc.).
Not that it's useless, but I don't agree with the people that review it as a definitive solution. Probably it's a decent gain for their needs, but not for me. Just my 2 cents.
Question: Is it possible to install another master cylinder or another lever to increase the leverage? Assuming of course that disengagement is not made impossible at that point.
