    Does anyone know anything about them good or bad
    And what would you recommend (19x18- 19x20 etc) for someone who likes a decent bite at the start of braking but not to strong and likes it to progress I'm not the type of rider who breaks into a corner I do all my braking before.

    Thanks

    Paul

    I'm taking it your talking about Master Cylinders? the industry leaders in this are Brembo .. never heard of the the name you bring up Paul…

    These type of braking systems are very very sharp and will stop your bike on a sixpence ….they are really too sharp for general road use if you are not use to them . They are mainly a track or race item for extra stopping power

    I know one lad who had one on for road use and braked as he normally would using the OE system….this was on a wet road and down he went after locking up the front…..they take some getting use to due to that extra stopping power …go easy on the wet Autumn leaves with this fella

    Thanks Dave, I have one a bit of research and various other forums like CBR fireblade forums people highly praise the brand

    I know brembo are the class leaders but I can't justify the price for them tbh

    Just a short spinet from their website

    ACCOSSATO master cylinders are used in many competitions, such as Superbike, Moto 2, Moto 3, AMA Superbike and are characterized by a really strong braking, so a short passive running.

    Is there a difference in the 19x20 19x18 etc

    Think the difference is in the piston diameter.
    Iirc the figures are stroke x bore.
    So you will get more fluid volume moved for the same distance of lever travel.

    Ive got one on mine, its awesome, the sizes are relating to piston sizes, depending on wether you want outright stoppppp or a bit of feel at the lever should determine the size you want.

    Its nothing to do with volume, as fluid is none compressible and the travel will always equate to the distance the pads have to travel before contacting the disc. A larger diameter piston in the master cylinder will apply more force to the pistons than a smaller one for the same pressure applied. The basic rulues of physics Force = Pressure x Area duduce that a larger diameter gives a greater surface area therfore more force for the same pressure applied.

    I like a bit of feel so what would you recommend ??

    19x20 if you prefer a firm lever or 19x18 if you prefer an equally strong brake but with slightly more travel in the pull of the lever. I went for the 18

    What do you think of them have you had problems ??

    No problems whatsoever, build quality seems very good, performance is really good, made a big difference in stopping power for me. 1 finger endos ! i got mine from bikersdicountstore when they had them on offer on tdr. I got the folding lever with a couple of adapters to convert to radial master cylinder and an inline brake switch for around 220.

    Would I need all the adapter and stuff cuz I think mine is already a radial MC not sure though

    you are best telling them its for the road, you will need a brake light switch on it ..and also dont run it on std hoses,changing the lines to braided will reap the benefits

    Spanners, have you got that back to front?

    I believe like sprockets, a smaller input diameter (Master cylinder or Front sprocket) will create a greater mechanical advantage, but less travel at the output diameter. A larger output diameter output (Slave cylinder or Rear sprocket) will also create a greater mechanical advantage, but less travel less for the same given input at the input diameter

    The GSX-R750 2005 is fitted with a Radial master cylinder as stock.

    Nope, we are not talking about mechanical advantage but basic rules of physics. May be my degree in mechanical and fluid power engineering got it wrong as well.

    You shouldnt need the adapter if your already running radials. You will need an in line brake light switch too.

    Sorry Spanners, I am not getting it. You appear to be say the opposite of this.

    It just recently got a full set of braided lines would I need a new set for the front with the new MC ??
