Which wheels for upgrading
In deference to the vast experience available here I have a simple question. Which later model wheels offer the easiest solution for the 16 inch tire dilemma?

Re: Which wheels for upgrading
If you can't find a swingarm, there's the drawing of a spacer to install a wheel with 20mm bearing in a 17mm axle and keep on using the oem swingarm. This might mean miss a part of the chain tensioning to keep the wheel far from the aluminium, but it's easier to do than to explain this!Finnpaso wrote:I think 907IE swingarm, wheels and brakes....
Do not forget to lift fron hugger (about 1/4") to let fron wheeel run freely
have a nice ride, Nicola

Re: Which wheels for upgrading
While this might be the simplest in terms of modifications required to accomplish,how hard is it to acquire wheels,brakes and a swing arm from a 907? I suspect it would be easier,for me anyway to add to my 906 swing arm than to find 907 parts at an affordable price. Also there a a lot of 900ss wheels to be had. I also suspect it will be easier to get michelin to make 16 inch tires than to find 907 parts. Are 907 parts truly a viable option these days?

Re: Which wheels for upgrading
If you can get a 907 swingarm assembly, it would probably be your best bet. If not, I'm sure you can make the stock 750/906 swingarm work. Some people have had the front of the "U" section trimmed and rewelded to allow for the taller tire profile, which is the main reason to want to switch to the 907 swingarm (it requires no modification).higgy wrote:While this might be the simplest in terms of modifications required to accomplish,how hard is it to acquire wheels,brakes and a swing arm from a 907?

To the best of my knowledge, the rear wheel from an early 90's SS750 or SS750CR (not SP) will work with a 907 swingarm and any other conversion. I have the front and rear wheels from a '94 SS900CR. I haven't assembled anything yet, but I am under the impression that the CR's rear wheel with OEM Ducati spacers and sprocket carrier will work with the 907 swingarm. I have all the components, but have not put them together. I think there is a post somewhere in the 750 section where a member assembled a rear assembly as I have possession of.
Any other swingarm, and you'll probably have to machine some spacers for wheel alignment and also possibly for wheel bearing conversion for the 20mm axle (if the wheel is not already set up for a 20mm axle). I have also seen a conversion using the '92-'95 GSXR 600/750/1100 wheels, which is the same as the '95-'98 GSXR-1100 wheels, also. If you are handy with machining and fabrication, or have the resources, I'm sure you can make just about anything work, though.

Re: Which wheels for upgrading
that`s the easiest possibility as also the chain alignment should be correct. Once in a while 907ie swingarms show up on ebay.If you can get a 907 swingarm assembly, it would probably be your best bet.
Except to one or two all Pasos with 17" conversion I`ve seen so far used the original swingarm.If not, I'm sure you can make the stock 750/906 swingarm work.
Also this is not really necessary. 17" with original swingarm is tight but it works.Some people have had the front of the "U" section trimmed and rewelded to allow for the taller tire profile, ...
The 750s SS or Monster usually use a 4.5" rear rim which gives most clearance if you stay with the original swingarm. A 5.5" will fit, too but max with a 170/60 tire. With a 907ie swingarm you have the choice. 5.5" with a 180 is not a problem. Of what I know the front 3 spoke Brembo rim is always the same for all 750, 900 SS, Monster, 851, 888, 907ie, 748, 916 (I would think for 600 also although they have only one brake disc). The rear 5.5" is the same on all 851, 888 and 900cc Ducs. The difference are the colours black, white, grey, gold. It seems to me that from 98 on when the Supersport i.e. replaced the old one the rim`s surface became rough while the older ones had a smooth surface. If you consider a combination with a 5.5" rear rim you can also go for the Marvic wheels used on the early SLs or Marchesini wheels used on some Monster, Supersport and ST models. (Some of the non Brembo rims use different sprocket carriers)To the best of my knowledge, the rear wheel from an early 90's SS750 or SS750CR (not SP) will work with a 907 swingarm and any other conversion. I have the front and rear wheels from a '94 SS900CR. I haven't assembled anything yet, but I am under the impression that the CR's rear wheel with OEM Ducati spacers and sprocket carrier will work with the 907 swingarm.
Anyone correct me if I`m wrong.

Re: Which wheels for upgrading
You are correct. It is not necessary as long as the tire profile is not too tall or you pay special attention to having the chain eccentric in the rear half of its travel to give more tire to swingarm clearance, unless I am incorrect in what I recall reading.paso750 wrote:Also this is not really necessary. 17" with original swingarm is tight but it works.
That clears up some of the questions I was having about the other options.paso750 wrote:A 5.5" will fit, too but max with a 170/60 tire. With a 907ie swingarm you have the choice. 5.5" with a 180 is not a problem.
Here is the assembly that I have accummulated...
1 - used 907 swingarm
2 - used 907 axle assembly
3 - used 907 rear caliper bracket
4 - used '94 SS900CR 4.5 Brembo wheel
5 - used '94 SS900CR sprocket carrier
6 - used '94 rotor
7 - new 907 sprocket carrier side spacer
8 - new 907 left side swingarm cap*
*Note - The left and right sides are different part numbers and the left is $10 USD more than the right, so I bought a right side to save a little money. The inside will probably need to be shaved a little to provide sprocket carrier bolt clearance.

Re: Which wheels for upgrading
i did the conversion and use a 5,5" rim, 180 tyre with the original swingarm.
the rims of the newer ducatis are compatible (750, 900, st2), the difference is the design, bearing, spacer inside the rim and brakedisk.
i had to machine the left eccentric and move the chain outward (ca. 5mm) to get a clear alignment of the wheels.
if i do the coversion today, may i choose the 4,5" rim or at least 170 tyre. the clearence is really less.
but the 180 looks good

Re: Which wheels for upgrading
There is a thread in the 750FAQ about making the change.
