Thinking of doing this on my old 750. However, I noticed that there are only three mounting bolts on the right side of my wheel. Do I need another wheel? Three doesn't seem enough.
There's 6 holes in the wheel.
They only use 3 bolts to hold that cover on.
Do it!! Great upgrade, did that on my 750 a lil while ago. You'll need (ideally) a larger master from a 900 or something, and I recommend brand name discs. I got Chinese eBay discs, although they looked great and were a great price, the runout was out of tolerance limit when brand new! The manufacturer specs allowed for over double the runout in their manufacturing process, so the game was lost before it began.
No saying others haven't had good experiences with eBay rotors, but I haven't.
Enjoy the awesome braking when it's done!
A word of caution.
Go easy on that lever until you get a feel for it.
It will be much easier to lock up with duals. :o
Word. Thanks dudes
It would be very interesting if you made some say 60 to zero stopping distance measurements with the original single disk setup and then again when you finish the dual disk installation.
I hate it when people make suggestions about things they think I should do.
Ironically enough I'm going to a single rotor/caliper for my "rat" 750 since I have the parts and want to acheive more lightness for that bike...so if you want my calipers/rotors/and m.cyl lemme know.
Don't know what it'll cost you to convert, but I got one of these a few years ago

switched to Ferodo Platinums, already had braided lines and I can't see how duals could slow that bike down better. I had thought about going dual, but advice on here then said lighter weight, last longer and better feel. They were right. Just my 2 cents.
What the....... don't stop with 2 discs! Go for 4!!

YOU beat me to it, bdfinally!! I was just about to post that info. I think you're way better off doing the single, BrakeTech ductile iron rotor with Ferodo pads. by adding a disc and calipers, you are adding unsprung weight and rotating weight...
with a proper lever you can do i finger stoppies with that setup....

I'm still kicking myself for not going this route. Would have had less weight, better quality braking components, and come in at about the same price or less. And have less clutter in front of my Carrozzeria wheels. :(

4-pad Brembo

Yeah, I dig the open look from the r side. I was considering just getting a better than stock rotor. Already have the braided line and I use Braking pads.
Suggs on the rotor? Im not looking for fancy, just better than stock with a simple look.
Not expensive and good, EBC V-Rotors, carriers can be ordered in colour or the regular X-Rotor and EBC pads . . .
Thanks, I'll look into that.

did the 749/999 caliper go straight on?
how do the iron discs fare with sintered pads do you know? i've always had the ferodo people here put me off the cp211 for road use.
Caliper went straight on.
Mated with a new Brembo Snowflake rotor that then lasted 24k miles of 70% freeway commuting, 20% rural and fun riding, 10% town riding.
The above pictured Iron rotor went on less than 3k miles ago, with new pads.
My S4 with dual Irons ran Platinums in the OEM 2-pin calipers for 19k miles, then CP211's in 4-pad calipers for 22k miles.
I'll check thickness, but they're not worn much.
I'd have used Platinums in the 4-pads if they offered them.....
The CP211's are a bit less grippy when cold, but nothing dramatic.
A couple stops and they're fine.
Just a quick question without threadjacking . . .
I have the opportunity to get a pair of 4pot/4pad 999 calipers, how much difference will it be against my 2pad/4pot calipers?
I have the Brembo RCS 18-20mm brake master
I would say definitely more power, but I've not run the same pad compound in both, so YMMV.
So you would say " go for it?"

Yes!
You will need a different brake line, as the inlet position on the 4-pads is different.
Seems like too much braking power for a 620. And a really limited/expensive selection of pads. Then again it might work really nice with the RCS.

beat you to it .. . I am offering $150 for calipers + lines . . . guy said yes . . . ;D
