UPDATED: Ebay Chinese Rotors: Fedex arrived today... new pics.

the radial MASTER CYLINDER from a 999 would be a good upgrade.

I did this.  Works great.  Even better if you can get the clutch/brake masters as a set... I personally really like the resivoirs.

so i've now bought metal gear discs to replay my chinese ebay discs after fitting Brad noticed a bit of runout. one disc had 0.07mm, and the other up to 0.1mm. for a brand new CNC milled disc, this is pretty poor in my eyes. i contacted the seller and they were good to deal with. They've told me their production tolerance is up to .15mm runout, which is alot! service limit is .3mm according to Haynes, so this is halfway there when brand new, and ok for them! so i'm returning the discs for refund at their suggestion, rather than replacement, which to me says something about their own view of their quality, if they dont have confidence this was a 'bad set', and others wont have similar runout. unfortunately i have to cover postage back, so im $65 out of pocket there, plus miss out on the savings i was hoping for by avoiding brand name discs.

on a side note, the whole brake upgrade has been pretty pearshaped, with Venhill sending me the wrong lines twice, and calipers taking over a month before falling through due to customs issues. 3 parts for the upgrade i needed, and hassles with all 3!

radial calipers will not mount on to your stock forks.
999's came with axial 4-piston/4-pad calipers for a while.
the 4-piston/4-pad style will be super mega over-kill for an S2R800, at least that's the popular consensus. dangerously sensitive braking.

the radial MASTER CYLINDER from a 999 would be a good upgrade. add some gold-line calipers (65mm mount, 4-piston, 2-pad, come in black or gold), and some 320mm, 10-mm offset rotors, and you should be good.

A bit off-topic; however related to the post above...

I have 999 masters and 999 4 piston 4 pad calipers on my S2R (w/ 320mm rotors of course), and it's just fine for me.  YMMV



I am using a banjo bolt with a small orifice (far left in image) to supposedly help slow down initial pressure (so I'm told), short levers, and normally use 1-2 fingers for the front brakes, so that may be a factor.


Before that I had S2R1k masters & calipers (4 piston 2 pad).  

The 999 4 piston 4 pad brakes do have more bite and require less effort than the S2R1K parts.  The same goes with the S2R1K brakes vs the S2R800 brakes.

Jumping from the S2R800 to the 999 brakes will be very VERY noticeable.

Getting familiar with the new parts is definitely recomended anytime you change something...especially with brakes.

Another thing to note with the 4 piston 4 pad calipers, there are few choices in pads, and the choices available are a bit more aggressive...even the stock pads.

what kind of pads are you running with these guys? my rotors are below spec, and my front pads wont pass inspection. I was thinking about picking up these rotors and a set of pads to go with them too.

I need them to work in the rain and cold. Any rusting on these?

If your monster can fit a 5 bolt 15mm offset (not sure if you ever messed with your forks) I have a set I can sell to you pretty cheap.

Never used them, bought them and then it turned out that the 796 is a 5 bolt 10mm offset rotor

They go fast though.  If none are in stock for more money there are these

i dont know what the offset or bolt number for mine. 

at $500 i was thinking about a set of these.

Ill probably pick up the beringers, to be honest $250 vs $500 for known high quality brakes (that look badass) isnt much of a difference.

Local shop has the EBC FA244HH in stock and the DP pads, not sure if either of them are any good for my application, which is to ride in nearly all weather and all temps, street, commuting and touring.

The ones for your bike are $549.
Either of those pads will be fine for you.

i think im going to pick up the EBCs.

if i mate them to the current rotors, can they be used again for the new rotors? im not sure when im going to pick up the beringers, and if i swap wheels ill have to keep one size.

If you need pads just sand them when you swap to new rotors.

If the old rotors have no scoring/grooves I might not even bother to sand the pads when switching.

took me a long time but, had to order new made in Italy rotors for my bike, the $279 for 3 rotors offer did not work, OK rear still on . . .

every time I was braking, a vibration on the front end . . . only at speeds under 15mph . . . one day just decided it was too much and took the whole wheel to friends machine shop . . . both rotors showed runout . .  then, one by one they came down . . . placed on the lathe, and turning by hand . . 0.2mm on one and  0.7mm on the other . . . friend took out some tools, did some work  . . no vibration felt but, new rotors had been allready ordered and installed . . .

Next rotors, EBC .  . .

[Rudemouthsky]

Being that it's been almost 2 years I thought those of you who purchased these could update us once again? Was leaning towards a pair of Braketech but an extra $550 for other mods sounds mighty nice...

..... the $279 for 3 rotors offer did not work, OK rear still on . . .

Same with me.
Inferior quality rotors, you get what you pay for!! I didn't bother machining down, as it'd just consume rotor material reserved for keeping it in spec thickness.

Maybe some have been lucky and got an ok pair, but never again will I be "thrifty" on primary components like braking or suspension/tyres!
