So...I have an 01 Sport....as youc an tell...and I'm interested in upgrading to a dual front rotor/caliper instead of just the one I have...

i'm wondering if the coffin style reservoir (which appears to be the same as the one on my boyfriends 01 750 monster) will take another caliper or if I need to upgrade to the remote mount style?

does anyone know for sure?

Re: coffin reservoir and additional front caliper? (01Sport)

you should prolly be able to run two calipers off one reservoir. but if you want to upgrade your brakes, SERIOUSLY look into replacing the single rotor you've already got with a full floating AXIS rotor by braketech.
you save weight
get better stopping power
you SAVE WEIGHT
and get better stopping power

yes i repeated myself. but it's a great solution and won't cost too much. you get to keep your existing master cylinder (though getting a goldline one off a 996 or 998 wouldn't hurt), don't have to buy a split brake line, don't have to buy a 2nd caliper and you get GREAT stopping power and save weight

We just converted my wife's single to a double on her monster. The master thats on there is a 13mm...what you need to go with is a 16mm if you run duals.

If I can get better stopping power with a single I'd rather do that since it's less work, potentially less money, and less weight....

now i guess I just need to find out where I can get that iron rotor at for the cheapest price....

and what kind of pad would I need with it? just a regular HH sintered pad or anything special?

how does that rotor handle street use? this bike is ridden daily so I don't want something that takes a lot of heat to get to where it will work for me...lol

Re: (01Sport)

Good suggestion Strati


I'm actually thinking about doing the same to my 620 project bike. It currently has the dual rotor setup. I'm thinking that if I get one axis iron or maybe even ceramic (hah) rotor and maybe upgrade the caliper I'll have all the stopping power I need (maybe even more than the stock setup). The stock dual rotor setup was actually more braking power than needed for the 620 engine. So if I switch to a single rotor setup I lose all the weight of 1 rotor+caliper+pads from the front. Interesting decision, just need the cash.

see, I've also thought about upgrading that single front caliper.....but then I would need a bigger mc still....

what would be the upgrade anyways? a six pistion would obviously be better....but from who? brembo?

Well you could get hardcore about it and get the 8 piston caliper from spiegler. But again it is probably overkill and it is $639+ just for the caliper.
You could go with an upgrade to a brembo four pad caliper ($195 from motowheels), but I'm not sure how much of an upgrade that would be. There is also the radial mount upgrade, but the showa fork lowers cost around $1000 and $209 for the cheapest radial caliper. For that kind of money you should just upgrade to lighter wheels and see gains in all aspects of riding.

Your best option probably is to upgrade to the axis irons, new pads, and at least a brembo goldline master cylinder. That should be on par or better than the dual rotor stock setup, which is pretty much overkill for our engine. Save the rest of the money for wheels or other mods more worthwhile.

Re: (jager)

Also, just as a side note...
I was getting new tires on the s4 a week ago and decided to give the brake system a good cleaning. I got the 02 s4 used back in oct and had upgraded to the radial MCs not too long ago. Anyway I was reading somewhere that it works great to use the 3M Roll Cleaners to sand the surface of the rotors. I tried it and it did.
Improved the feel a good amount. At first I thought something was wrong.
Of course over time it will get back to the way they were, but then you just sand 'em down a little again.

Yeah - not so sure this makes sense on a 750 sport

lol

I'm fully aware that my bike is on the low end of the totem pole for ducs....so I don't want to spend all kinds of money on it....that will have to wait till I'm out of college (DECEMBER!) and will be getting a new duc (broken between a 998 and a SS100DS).

As for the upgraded MC....will I be able to use one that comes stock on a dual rotor bike? or will I have to get a smaller one since I will only have one caliper?

even then, would it be worth it?

Re: (01Sport)

stock m/c and goldline caliper are fine for running the AXIS. get a single rotor and ferodo pads for it and yer good to go. if you want to go further than that once it's all on, keep a lookout on eBay or the classifieds here for a goldline master cylinder and a 4pad caliper off a 749 or 999. but believe me. once you get the AXIS and ferodo pads, you'll be happy with the results.
for what it's worth, i'd upgrade the m/c before the caliper in your case.

vendors? ca-cycleworks.com and motowheels.com both carry 'em.
