Less weight... All things being equal a wave disc will weigh less. I wouldn't use them up front but as I don't do much rear braking then a wave at the back gives some benefit...
In answer to your question, I fitted one of Brembo's high carbon Oro discs to the rear of a previous bike...definite improvement on the OE kit. I'll be doing the same to the MTS once the current pads are dead.
Who's not interested? The back brake on the Multistrada and its well -known shortcomings have been debated to death for years. The problems with the master cylinder, hoses, and caliper, the overheating fluid, the upgraded parts, the difficulty in bleeding properly - there are threads about these topics and more. I do not recall seeing anyone suggesting the disc itself was a problem before. And if it is a problem, I do not recall anyone suggesting wavy discs are the solution. I'm still not too clear what the reasoning is, but if you want to give it a try, go ahead. Interested to see how it goes.
Hi Doodle, given that they sent me the wrong disc and have yet to confirm they can supply the right one, I may well fit an oro disc too. (nice and round). I didn't think they made an oro for the mts 1200 yet but a bit of research has given the part number68B407H1 (same as the panigale)
It wouldn't surprise me to find that the disc is the same/functionally similar to other models in the range, the 1198 may also be a likely candidate.
How about fitting a 320mm disc, a 4 pot caliper on the rear, with a manually adjustable bias valve? That should see you right.

I thought I posted about this a few months back. I spent ages talking to the maker and they felt that the abs model was rare. At the MCN meet for the MTS I found 100% of the machines had abs. Never got them to agree, so got my money back. As standard the MTS rear brake is p1sspoor. Brake now acceptable. 1-clean disk to remove any chain oil. 2- decent pads, soft as possible. 3- abs mounted bleed nipple. 4- bleed by turning bike upside down....OK, just the rear caliper with spacer in middle. 5-bleed at abs unit. Result means can activate rear abs at any speed in dry. Decent brake fluid & fresh /new.
I for one am interested in anything that makes the rear brake more efficient, just because some of us don't get involved in technical spats doesn't mean we're not interested in the real world feel of a different component, especially in a very well documented weak area on our otherwise fabulous toys.
Thanks aircon, I have already done all of what you mention. must have missed the bit about the disc though. the pedal is great to start, but performance is still poor compared to other bikes, so looking to improve it. i also still suffer from long pedal travel after a week of serious use (eg 6 days in the alps), even with rbf600 fluid. i will post my findings, for those interested.
I upgraded the brakes on my old GSXR600 to Galfer wavey discs with matching pads and braided lines after a couple of track days showed the standard ones weren't up to the job after a few hard laps.... I can say without a shadow of a doubt they were amazing, not just in relation to the standard ones but in relation to every other bike I've ridden! I don't know the technicalities of why they worked so well with less surface area, low chromium content etc, all I know is that once bedded in they had incredible stopping power and stood up to heavy stop after heavy stop without any fade or change in feel. It was the best £500 I've ever spent upgrading a bike. On the last trackday I did on it I passed one of my friends on his Blade at the end of the main straight, he assures me that he was rolling off to brake and I went past still wide open, they just gave so much confidence in how late and hard you could get it pulled up. So yes they work, they look good and I don't know why....
... with that said I can't see much benefit in having one on the back?... I hardly use it other than low speed stuff and even then the fact it has so little grab makes it easier to use
Galfer have confirmed they don't do a disc for the mts.I am therefore fitting a brembo oro disc. For those interested hps did quite a bit of leg work on this, so they deserve a heads up. Highly recommended by me anyway. Also they have managed to find some carbon loraine pads. These used to be distributed by the Pirelli importers, but they stopped doing so a year or so back, which is why they are hard to find now, and why dealers now stock bendix etc. I have re-bled the rear brake with fresh rbf600, bleeding from both abs pump and the rear caliper. We will see how much difference it all makes next weekend. Just had the rear preload unit rebuilt by Steve Jordan's too. Only needed new seals
BrakeTech do both Iron & SS rears. I'm just about to have my iron fitted (3/11). Email Jeff @ BrakeTech for availability. Or contact Ebrew at the sister US forum. He has sold and parted his MTS out and still has BrakeTech SS rear rotor (floater bobbins too) available.
Everything has pros and cons. The best normal disc is cast iron, but it weighs 2 or 3 times as much as the alternatives and is a rust magnet. If the back brake is too good then the wheel locks up. Yes, using both brakes can give you better braking, but since there is not splitter, you need to constantly adjust the force to maintain the improvement. The only bikes that have a real need of a back brake are used for stunts. For normal use they just improve engine braking a bit. 99% of the time, the only use I have for the back brake is when stood at a junction.
Thanks for the heads up MJW, I have sent him a pm. Did you get yours direct, or through a uk distributor ? Would be interested to hear price etc, because I was told these werent available yet. Pm me if you prefer. Cheers, John. [ps, got a reply and he traded the bike with it still fitted]
