couchcommando Posted April 1, 2020 Report Share Posted April 1, 2020 Looking for a bike that uses 2 twin piston calipers along with an axial master cylinder with an external reservoir. Want to change the master cylinder on the VFR which is the honda one with a built in metal reservoir. Has to be axial not radial. Guess I'm looking for an older jap master cylinder with a round plastic reservoir, any ideas ? Assuming 16mmx18mm ? Quote Link to comment Share on other sites More sharing options...
TLRS Posted April 1, 2020 Report Share Posted April 1, 2020 Ought to be a bore size on the m/c that should help the search? 12,5mm? Quote Link to comment Share on other sites More sharing options...

Bore size will be stamped on it - off the top of my head, something like a CBR400RR has similar sliding two-pot Nissins, but a remote reservoir m/c. It'll likely be a 14mm, 5/8 or possibly 1/2. All of which are pretty common across most Japanese manufacturers, shouldn't be any issue finding one. Quote Link to comment Share on other sites More sharing options...

couchcommando Posted April 1, 2020 Author Report Share Posted April 1, 2020 Thanks guys some ideas Simon, thanks but firestorm has 4 pots 👍 Quote Link to comment Share on other sites More sharing options...
couchcommando Posted April 1, 2020 Author Report Share Posted April 1, 2020 BIt of digging looks like the VFR is 1/2”, an SV650 is 5/8” so would that give a nice improvement ? The discs are also up in size from standard 296 non floating to 310mm floating Quote Link to comment Share on other sites More sharing options...
