Also i am intrested, cause i have already 907 swingarm for my 750 Paso waiting to 17" swap, but i dont start modification, before i have used my new 16" Michelins and if cant find anymore those tires, or another 16" tires. Paso looks better with 16" wheels... :smoke:

I recently picked up a 907 swingarm, also, and it appears to be a direct swap into the frame and suspension linkage. I compared it with a spare 750 swingarm, so a side-by-side comparison looked like a direct swap. As for the axle, I'm not sure. I didn't measure the two to compare them. I don't know if the axle adjusters are the same as a Monster or 888, but I do know that both swingarm end covers (the gold ones that the adjuster bolt goes through) are still available from Ducati. Oddly, they are listed as separate part numbers, and the right one is $25 USD and the left one is $35 USD. I'm not too sure about the caliper bracket, as it is part of the inner bearing race support, so it's width will be somewhat dependant on which wheel you plan on using.

If I think about it, I'll try to take a picture of the 907 and 750 swingarms when I get home.

done that longer time ago.
Click on the pic to see the overview of pictures or just go on "next":

The front bearings are the same so the axle diameter is also. As both swingarms are identical in the front part the axle swingarm/engine should be the same.

I'm not so sure about chain tensioner's mounting in the axle. There're two great differences between P750 axle and 907ie one: the lenght and the chain tensioner, I suspect they're quite different!
In parole poere: e il millerighe? sei sicuro che sul tenditore assiale sel 907ie ci vada senza problemi?

What you mean for MILLERIGHE???
signs marked on the hole of wheel axle??
Do you think that wheel axle and chai rgister are different from monster 888 series??

Nicola cosa intendi per millerighe??? ,
i segni che si vedono dove si inserisce il perno ruota???
pensi che l'insieme perno-tendicatena sia diferente dalla serie monster 888 etc??

The 16" rim has a different chain tensioner sistem from 17" one.
In the 16" you have a sort of alluminium bush in each side of the axle, that is to spin in a circular seat of the swingarm; to make the bushes spin at the same time, they have a sort of tread (like a very thin gear) that matches in the wheel axle, that has the corrispondent gear/tread (what the H*** is the english for this???), so the entire assembly bush/axle/bush can spin altogeter.
17" rims on 907ie and earlier ducs, have a standard chain tensioner, that does not require the bushes and the tread
Just have a look to the pics in the gallery to realize what I'm saying

I cerchi da 16 hanno un sistema di tensione della catena fatto con le due bussole laterali che ruotano nelle sedi della forcella; per ruotare esattamente della stessa misura, hanno un incastro fatto come una specie di ingranaggio a denti fitti, che ha la corrispondenza sul perno ruota, cosicchè quandi il tutto è assemblato, puoi tirare la catena avendo sempre la ruota allineata.
I cerchi da 17 non hanno bisogno di questo sistema perchè hanno untendicatena tradizionale (due buloni, uno per parte), quindi non so se il perno del bucefalo è adattabile

Nicola I UNDERSTAND,I KNOW THAT THE CHAIN TENSIONER OF 750 IS DIFFERENT...THE BEATIFUL ECCENTRIC.... BUT I HOPED TO MOUnT MY OLD AXLE :-(

Now i'm searching for a 17 mm axle and a chain tensioner....
i hope at a good price...

You might be lucky and be able to machine a spacer to install inside the swingarm and fix it to the tensioner... have you asker for some pic of the axle and the drawings?
Wich bike comes the rim from? maibe an used axle should be the easiest solution...
Se hai (tanto) fortuna potresti essere in grado di tornire un distanziale da inserire dentro la forcella per adattarlo al tenditore...n Hai provato a chiedere in giro per qualche foto e le misure?
Che cerchio hai trovato? forse un perno usato è la soluzione più facile...
