master cylinder advice
 

Hi All,

I'm gonna change the stock master cylinder on my race bike (curvy) as the brakes still dont have a sharp feel to them, even after I've fitted newer calippers from a crashed k7, braided lines , race fluid and race pads.

Is there another/better stock Suzi master cylinder that some of you have tried, with better performance?

thanks in advance

Gixxer ones are larger so more powerful

I had a Gixxer radial one on my Curvy. The brakes were definately stronger and had more feel too.

thanks for the replys..... I take it they fit straight on (same size clip ons)

cheers

Surely gixxer calipers are what you want? Adaptor plates are available from dirtydog on here

We think the mastercylinder is the prob, maybe we will have to go the route youre saying..... I have tought bout it. Gixer calipers aint cheap though.

cheers

Ah, didn't realise you were a racer & probably knew all about them anyway.
Be interested to know how you get on with the MC if it makes a big difference :thumbsup:

Recent R6 and R1 m/c is a very nice part- it's Brembo designed but built in-house by Yamaha. Well made... And it's a 16mm, which is more or less the equivalent of the stock item, though the pivot point is different. It works very well with the stock calipers I feel, though that's very much a matter of taste, it's got slightly more effective power but it just feels better, very direct. It's similiar to a direct upgrade. I still have one on mine, and I feel no urge to upgrade, even though I've used the billet superbike-spec Brembo m/c, you'd think that'd spoil me for anything less but it doesn't.

The GSXR Tokico 18mms, I didn't get on with at all, fair play I was comparing it with that brembo 18mm, and it didn't compare well... Squashy. Flexy. Distant. Generally like a more powerful SV m/c, it was strong but it wasn't good. It's fairly typical of OEM spec m/cs, I think Kawasaki might actually use the exact same part, Triumph use a similiar one. It doesn't really flex much at all but it was enough to be offputting for me.

Your mileage may vary, of course, there's a huge slice of personal taste in this. I like a long lever throw with as linear braking as I can get, I don't like bite and I don't like ramping. But I think for race use, bite is probably good and ramping could be. And not everyone likes the long throw, because of psychology as much as anything else, short travel tends to feel more powerful and very direct and connected. But long travel gives me more control, I think, I just stop better with it.

FFS. That isn't how hydraulics work at all.
