Right, so there’s been a number of threads and lots of chat about new floating carriers for the ‘90’s cast iron floating brake rotors that were on Superlights, SS/SP’s, 851 SP’s, and a few other bikes. So now it’s time to get this underway.

Let me also state up front here, that I have no interest or association with whoever makes the carriers, or anything else, I just need a new set of carriers for my 851 SP3.

As has been previously stated, new rotors can be made from a 7000 series alloy, which is harder than the original 6000 series alloy carriers. However the manufacturer needs a number of sets ( 13 pairs I believe? ) to make it worth his while. Surely between all the bikes out there with these rotors, and everyone that has expressed interest in the previous threads, we can get 13 solid orders. Pricing is yet to be confirmed, but the talk on one of the other threads was in the region of USD$400 for the pair.

I’m sure someone appropriate will chime in with more accurate info and pricing at some stage.

The manufacturer will need a sample as well, so they can make the new ones as exact copies of the originals. So if no one in the US can lend them one, I will send one of mine from Australia.

So, please don’t whore this thread out with “yeah I want some but they’re too expensive”, “ my discs spin on the carriers but they’re fine”, or “ my $150 Chinese eBay floating rotors are the shiz”, please go to the other threads for that. Please only reply if you are serious about putting your hand up for a pair and have the coin to do it. Please also state how many pairs you want.

I’ll start the ball rolling with 1 pair, shipped to Perth. I’m more than happy to combine shipping with anyone else in Perth who wants some ( Julian, Graham? ).

I looked at replacing the buttons when I mounted the rotors on my new carriers. I have two complete sets of original carriers and rotors each of which has done 30,000 km. The alloy carriers were completely flogged out on both sets around the buttons. However visually the buttons original anodising surface looked perfect and when we put the vernier measuring calipers on the buttons we could measure zero wear as you would expect. This is because they were hard anodized at the factory and have a near diamond like surface hardness in comparison to the standard anodizing on the carriers...so of course it is the softer surface of the carriers that have worn not the buttons.

Removing the buttons and replacing them is very simple, you just chip off the small dob of brittle epoxy that the factory placed on the circlips with a small flat bladed screw driver and then remove the circlips. When reinstalling them you will want to replace the epoxy you chipped off with a small dob of araldite two pot epoxy resin (or similar) on one end of the circlips as was originally done by the factory. Once you have the disc assemblies off the bikes it takes all of about 20 minutes to remove both your discs from the old carriers and mount them up on your new carriers.

The Corse Dynamics machinist has a set of the rotors and is working on a prototype that should be delivered to us as soon as next week. Once we approve for production, it will only take another two weeks for production and anodize. We can make them available with or with out new buttons.

How did the prototype go?

Are these going to be hard anodised or regular anodised?

Are these in production yet and, if so, are there any sets not spoken for?

If MotoWheels are not proceeding with their ones or are not doing hard anodized ones I am happy to make some more. If they are doing some I am happy to stand back and let them have the market.

We are waiting for a prototype to fit check.
The crew just got back from MotoGP on Monday.

The hard anodising is important.

Someone asked me if I could have made them cheaper out of the original weaker alloy and pointed out that none of the orignal ones ever broke.

And the answer is yes we could have. And they are right the stonger 7075-T6 is not needed for strength, The problem with the original carriers was not that they were made from a weaker alloy - it was that the standard anodising process used proved to have a predictably too soft wear finish. I went through two of the original sets in just 40,000km and I do nearly 20,000km a year on my bike. Yes you could hard anodise the original alloy but you would probably just create the effect of a hard wearing but brittle egg shell over a softer base material.

Just why the originals were not hard anodised is not too hard to guess at. Ducati had previously used similar full floating disc carriers only on race bikes which did very limited mileage and so the wear was probably not an issue that had caught their attention.

The 7075 we used and that I understand Motowheels is also planning to use for their carriers gives a much better base for the hard anodising and it is the hard anodising (not the slightly tougher base material) which will give the surface the 'diamond hard' finish that you need to stop the hard anodised buttons wearing out the carriers. The fact that the original buttons were hard anodised is proabably why I have never measured any wear on any of the original buttons and why you never need to replace the original buttons.

If Motowheels are making them out of 7075 and hard anodising them as I did for mine, then their pricing below is a very good deal. Please note I have no more sets of the limited production run of carriers I did available for sale and at this stage I have no plans to do another production run while someone else is offering to meet any demand for a superior product.

Corse Dynamics was the company that offered to make the production run for us. They actually asked us to take 15 sets - we will put 2 sets on the shelf to make this happen if there is enough interest - so we only need a total of 13 buyers. Price was $400/set.
-M

Incidentally if you don't insist on replicas the Braketech discs from Motowheels also look really good (and are no doubt lighter in weight) - I was sorely tempted in a set of them but decided to stick with the original look - I love the very clever design of the Braketech ones.

Are you guys actually making any progress with these? You have tallied about them for a very very long time. I don't want to tread on your toes and I can't match your price (given that the ones I did use an expensive two step hard Anodising/ colour matching treatment) but if you are not going ahead with yours I am happy to do another run to meet the albeit limited demand? Can you advise what your plans and progress is for everyone who is interested?

Moto, can you please tell us where you are up to and if you are going to finish the project or abandon it. This is starting to drag on somewhat and patience is starting to wear thin.

Another outfit now has a proven product, so if you don't want to complete yours for whatever reasons then no hard feelings, but we need to know soon as riding season for some of us is fast approaching, and WE NEED BRAKES TO RIDE!!!!!!!

Thanks.

Seeing as there seems to still be interest and the other guys don't seem to be proceeding with theirs...so I don't think I am treading on any toes.

I have been asked by a couple of mates in the Ducati Owners Club to make some more replica carriers and I have agreed to do another limited production run. This will probably be the last production run of relica carrriers I do.

These will again be done out of 7075-T6 (much stronger tham the original soft material) and will be hard anodised and gold colour matched in a two step process.

We ordered the billet today and I have booked the CNC machine for mid next week.

That's great news...

How much $$$ for a pair - and how do we get on the list...?

Mitch they are same price as last time $345 NZD per carrier. To order it's best to email me. [email protected]

I'm sure they're awesome, but $690.00 for a pair - for just carriers - is too much to justify.
The original post was $400.00 a pair, and that was a lot for these old bikes...

I can't do it.

Thanks for the work you do.

Please note that is $690 NZD which I think is a lot less in US dollars.

We fully appreciate at this cost they are not for every one and thats why we are only doing a very small production run.

That $400 USD quoted was for the ones Motowheels were going to do. It is possible that they discovered that there was no profit at that price and that's why they never produced any. Machining these out or 7075-T6 is a lot more complicated than it first appears because of the nature of 7075-T6 billet and need for the finished product to be perfectly true.

Further we understand their ones were just going to have a decorative gold anodising on them where as we do ours with two step process so that we can hard anodise them first which is the real secret we believe in getting them to last a very long time. It makes them more expesnive but it also makes them a product we can sell with confidence that they will last much better than the originals.

But I do appreciate that if you are not after origninality there are cheaper options around.

Mitch many thanks for your consideration.

We now have just four sets left unsold in this production run of ten sets. As I said before I think this will be the last production run we do of these.

Sorry, that we have not made much progress on the rotor carriers.

Our machinist has a big government job to finish. Since that pays the bills, he really has to focus on that to keep his doors open. He gives us great deals on group buys but it requires patience on our part (or a lot of pre-planning). We can go to another machine shops to get work done, but the price will be a lot higher.

Just a notebon this. We have never found a set that needs the buttons replaced. The buttons don't wear because the original carriers were so soft.

Maybe I speak for others:

I'm greatful that you guys - Moto / FastBikeGear - have taken this on. Having these made will never make anyone rich.

But for me, and the 900SS/SP these will go on - I have to be careful how much I spend on a bike that is only worth probably $4K max...

That said - I committed to buy one set from Moto at $400.00, and I will honor that if they are produced in some reasonable timeframe.
