KR-1S.co.uk Forum

Just had a look on evilbay and they all seem o be made in Thailand or China for about £19 new

So.... i'm after one off a jap bike but which ones will fit my KR1S set up ?
Does anyone have a list of compatable Radial front master cylinders to fit the the KR ?

I have one off an unknown GSXR - however I had to get longer hoses as the std KR ones wouldn't reach!
Cheers

Is it a 19mm bore i need ?
Plus the ratio as in 20 or 18 etc which ratio do i need ?

mine is 16x18 (brembo) but this came from an rs h***a. it works very well though with much better power AND feel. i also have a nissin one off the newer zx6r to put on the other bike. i think any of the new bikes m/cyl will give a vast improvement over std tired units. i know of gsxr though ones been used on rgv's which will work well on kr calipers. roughly the same design/pistons ect. elf has a very nice one from moto46. bought for a very good price aswell i think.

Any of them will fit just using longer hoses. R1/R6 are smaller bore than suzuki's
I have one of these

Its awesome Adjustable reach on the go and also adjust able Ratio on the lever.

i contacted Fowlers and they have this one
it's a Nissin 19mm type and comes with the brake switch etc

I have now ordered one of the above nissin radial master cylinders.

Does anyone know if i'm best running the brake lines with a splitter like standard or 2 seperate lines to the m.cylinder ?

PM'ed yer Charlie Boy

Its funny PB mag did a teat this month on brakes for a GSXR 1000 they update the calipers on the K1 to later calipers and it Improved the stopping distance They then changed the master cylinder to a radial type and the stopping distance INCREASED they said that the master cylinder was not a good match for the calipers!!!!

doesn't make any difference for the performance.

when fitting aftermarket brake lines, 2 long ones are cheaper than 3 short ones

I've been reading a bit on braking just recently & the jury is out on whether two lines split at the master cylinder are better than one main line split at one caliper looping over the wheel to the other caliper. Or if the standard setup is just fine for the average rider.

I guess its just down to what you are using the bike for. It seems that two long lines split at the master cylinder are better for racing purposes. And a normal setup is more than adequate for the road.

I personally base my choice down to how the bloody brake system looks. Yes I am that shallow

Perhaps not better for racing but an ACU regulation that they must come from the master cylinder in two lines.

It's a rule of hydraulics that the pressure is the same at all points in the system. You could run the lines anywhere you want and it wont make a scrap of difference. Whatever makes you sleep well at night is the way you should do it

So this is ok then?

It says the same on the other side too (picture in B/W to clearly point out the route the hose's have taken)
I really do have too much time on my hands on a thursday

Sorry Headcoats, we really have gone a bit off the topic here.
