brembo radial master cylinders have been on for a while now and the front brake is bloody brilliant.

however the clutch is still heavy. Fluid is a beautiful colour and I don't think there's any air in there.

Is there another step to be taken towards getting a lighter clutch?

1200 SE

thanks guys

The RCS 16 I put on mine reduced the pull by 33%.

If yours hasn't reduced by a similar amount, then there's an issue somewhere, either at the RCS end or slave end.

Ummm somethings getting lost in translation here,

my clutch pull is about 33 percent lighter than before but my question is.... is there a way to reduce the the pull any further?

Cali 1400 Clutch. It's a bit lighter than a 2013 clutch, but it's an expensive option for maybe another 5%.

Jon's (lcjohnny) Oberon clutch slave cylinder?

you just to need to install a cheap 12- 13mm piston diameter clutch master cylinder, and you would be amazed

Like the Brembo PS13 for example

My rcs 16 Brembo Corsa Corta clutch master works awesome now..I have run one on my last 3 Moto Guzzi's and I have one on my Ducati and Aprilia as well..Very nice.

Has anyone tried the Brembo RCS 14x18-20 clutch master? They seem to be rare, but the size would be even closer to the stock 11,9 mm piston diameter. So the radial function should counter the heavier pull that a larger piston normally includes. Any thoughts?

What would be the point of installing one “ even closer to stock” might as well just run the stock one then?
Where would your advantage be?

From going up in piston sizes on the brake side I know that pushing diameters too far might result in a wooden lever feel with a lot of pull force for little travel. My GRiSO is a 2005 1100 and although thoroughly bled the clutch still leaves a lot of room for improvement. After seeing pictures of damaged bores I see little value in a repair kit, if not the piston, but the bore is the problem - I´d be throwing money upon old stuff. I got the money for the RCS, but want the best solution. And I am waiting for the Guzzi-batch of the Oberon slave cylinder, but this might take another 6 months.

A smaller master cylinder piston (or a larger slave piston) gives a lighter lift.

The Brembo Corsa is only lighter because it is better designed with less thrust lost to sideways pushing on the piston.

So a 12mm Corsa would be ace
