Oberon Clutch Slave Cylinder

Just bought the Oberon and now want to buy a radial clutch master cylinder to match it. I want it disengage without pulling all the way back to the bar. Any of you have experience with what size worked best for this?

you'll probably need a 19 bore master, which will essentially nullify the purpose of the oversized slave.


the oberon with the brembo rcs16 needs to go to the bar to fully disengage.

I also ordered the Oberon slave cylinder but my local shop special ordered me an RCS17 and told me that was what Brembo recommended. Is that right? What would happen if I ran the RCS17 master with the Oberon slave? Thanks in advance.

it'll be fine with a 17, it's fine with a 16 even, but a much longer pull

Wibbly, Is this the case for the TSR Slave also. I bought one from Simon but have not tried it with my rcs16

you'll find that the lever feel is amazing with the 16rcs and the oversized slave. i had to set my lever as far out as i could, but pulling the lever to your knuckles wasn't enough to fully disengage the clutch and get smooth downshifts. i'd have to use four fingers and pull it to the bar.

same goes for pulling away off the line from a standstill

I had to pull the lever in all the way when trying to go through the gears quickly down the straightaways on the track. It was frustrating for me, because too often I would not engage the lever back enough and get false neutral. I thought getting the TSR would help. I wish I could put my CBR cable clutch on my RC-51. I hope my Q/S will solve this problem a bit.
